Group of answer choices
A. Wildcard
B. The Tab key
C. Regular expressions
D. The Escape key
Answer:
B. The Tab key
Explanation:
In this scenario, You are entering command that operates on a file. The path to the file is lengthy and confusing and you are afraid that you will misspell part of it. You can help yourself out via the use of the Tab key.
When working with the command line prompt (cmd) on a Windows, Unix or Linux computer, typing file paths is sometimes difficult or considered to be a burden because they are lengthy (too long) and perhaps confusing to the user. To help yourself out, you can always use the "Tab key" to autocomplete names of directories or file paths in an alphabetical order, while in the command line.
Additionally, pressing the "Tab key" continuously while in the command line would cycle or toggle all available commands in an alphabetical order.

Write a copy assignment operator for CarCounter that assigns objToCopy.carCount to the new objects's carCount, then returns *this. Sample output for the given program:
Answer:
Here is the copy assignment operator for CarCounter:
CarCounter& CarCounter::operator=(const CarCounter& objToCopy) {
carCount = objToCopy.carCount;
return *this; }
The syntax for copy assignment operator is:
ClassName& ClassName :: operator= ( ClassName& object_name)
In the above chunk of code class name Is CarCounter and object name is objToCopy.
Assignment operator = is called which assigns objToCopy.carCount to the new objects's carCount.
This operator basically is called when an object which is already initialized is assigned a new value from another current object.
Then return *this returns the reference to the calling object
Explanation:
The complete program is:
#include <iostream> //to use input output functions
using namespace std; //to access objects like cin cout
class CarCounter { //class name
public: // public member functions of class CarCounter
CarCounter(); //constructor of CarCounter
CarCounter& operator=(const CarCounter& objToCopy); //copy assignment operator for CarCounter
void SetCarCount(const int setVal) { //mutator method to set the car count value
carCount = setVal; } //set carCount so setVal
int GetCarCount() const { //accessor method to get carCount
return carCount; }
private: //private data member of class
int carCount; }; // private data field of CarCounter
CarCounter::CarCounter() { //constructor
carCount = 0; //intializes the value of carCount in constructor
return; }
// FIXME write copy assignment operator
CarCounter& CarCounter::operator=(const CarCounter& objToCopy){
/* copy assignment operator for CarCounter that assigns objToCopy.carCount to the new objects's carCount, then returns *this */
carCount = objToCopy.carCount;
return *this;}
int main() { //start of main() function
CarCounter frontParkingLot; // creates CarCounter object
CarCounter backParkingLot; // creates CarCounter object
frontParkingLot.SetCarCount(12); // calls SetCarCount method using object frontParkingLot to set the value of carCount to 12
backParkingLot = frontParkingLot; //assigns value of frontParkingLot to backParkingLot
cout << "Cars counted: " << backParkingLot.GetCarCount(); //calls accessor GetCarCount method to get the value of carCount and display it in output
return 0; }
The output of this program is:
Cars counted = 12

In C++
Answer:
The program written in C++ is as follows
#include<iostream>
using namespace std;
int main(){
string lname, fname;
cout<<"First name: ";
cin>>fname;
cout<<"Last name: ";
cin>>lname;
cout<<lname<<", "<<fname;
return 0;
}
Explanation:
This line declares lname, fname as string to get the user's last name and first name, respectively
string lname, fname;
This line prompts the user for first name
cout<<"First name: ";
This line gets the user first name
cin>>fname;
This line prompts the user for last name
cout<<"Last name: ";
This line gets the user last name
cin>>lname;
This line prints the desired output
cout<<lname<<", "<<fname;
The program in Python is
person_name = input("Enter your first name and last name separated
by space: ")
split_names = person_name.split( )
first_name = split_names[0]
last_name = split_names[1]
print(last_name + ", " + first_name)
The first line of the program requests the first and last names as a single string, separated by a space.
The next line splits the name into first and last names
Finally, the print statement displays the names reversed, but separated with a comma

The factorial of a nonnegative integer n is written n ! (pronounced "n factorial") and is defined as follows: n ! = n · (n - 1) · (n - 2) · … · 1 (for values of n greater than or equal to 1) and n ! = 1 (for n = 0). For example, 5! = 5 · 4 · 3 · 2 · 1, which is 120.
a) Write a program that reads a nonnegative integer and computes and prints its factorial.
b) Write a program that estimates the value of the mathematical constant e by using the formula:
e = 1 + 1/1! +1/2! + 1/3! +.......
c) Write a program that computes the value of by using the formula
e^x = 1 + x/1! + x^2/2! + x^3/3! +.......
Answer:
Here are the programs. I am writing C++ and Python programs:
a)
C++
#include<iostream>
using namespace std;
int factorial(int number) {
if (number == 0)
return 1;
return number * factorial(number - 1); }
int main() {
int integer;
cout<<"Enter a non negative integer: ";

return number * factorial(number-1)
integer = int(input("Enter a non negative integer: "))
print("Factorial of", integer, "is", factorial(integer))
b)
C++

double factorial(int number) {
if (number == 0)
return 1;
return number * factorial(number - 1); }
double estimate_e(int num){
double e = 1;
for(int i = 1; i < num; i++)
e = e + 1/factorial(i);
cout<<"e: "<< e; }
int main(){
int term;
cout<<"Enter a term to evaluate: ";
cin>>term;
estimate_e(term);}
Python:
def factorial(number):
if number == 0:
return 1
return number * factorial(number-1)
def estimate_e(term):
if not term:
return 0
else:
return (1 / factorial(term-1)) + estimate_e(term-1)
number = int(input("Enter how many terms to evaluate "))
print("e: ", estimate_e(number))
c)
C++
#include <iostream>
using namespace std;
int main(){
float terms, sumSeries, series;
int i, number;
cout << " Input the value of x: ";
cin >> number;
cout << " Input number of terms: ";
cin >> terms;
sumSeries = 1;
series = 1;
for (i = 1; i < terms; i++) {
series = series * number / (float)i;
sumSeries = sumSeries + series; }
cout << " The sum is : " << sumSeries << endl; }
Python
def ePowerx(number,terms):
sumSeries = 1
series =1
for x in range(1,terms):
series = series * number / x;
sumSeries = sumSeries + series;
return sumSeries
num = int(input("Enter a number: "))
term=int(input("Enter a number: "))
print("e^x: ",ePowerx(num,term))
Explanation:
a)
The program has a method factorial that takes numbers as parameter and computes the factorial of that number by using recursion. For example if the number = 3
The base case is if (number == 0)
and
recursive is return number * factorial(number - 1);
Since number = 3 is not equal to zero so the method calls itself recursively in order to return the factorial of 3
return 3* factorial(3- 1);
3 * factorial(2)
3* [2* factorial(2- 1) ]
3 * 2* [ factorial(1)]
3 * 2 * [1* factorial(1- 1) ]
3 * 2 * 1* [factorial(0)]
Now at factorial(0) the base condition is reached as number==0 So factorial(0) returns 1
Now the output is:
3 * 2 * 1* 1
return 6
So the output of this program is
Factorial of 3 is 6
b)
The method estimate_e takes a number i.e. num as parameter which represents the term and estimates the value of the mathematical constant e
The for loop iterates through each term. For example num = 3
then
e = e + 1/factorial(i);
The above statement calls works as:
e = 1 + 1/1! +1/2!
since the number of terms is 3
e is initialized to 1
i is initialized to 1
So the statement becomes:
e = 1 + 1/factorial(1)
factorial function is called which returns 1 since factorial of 1 is 1 So,
e = 1 + 1/1
e = 2
Now at next iteration at i = 2 and e = 2
e = 2 + 1/factorial(2)
e = 2 + 1/2
e = 2.5
Now at next iteration at i = 3 and e =3
e = 3 + 1/factorial(3)
e = 3 + 1/6
e = 3.16666
So the output is:
e: 3.16666
c)
The program computes the sum of series using formula:
e^x = 1 + x/1! + x^2/2! + x^3/3! +...
The for loop iterates till the number of terms. Lets say in the above formula x is 2 and number of terms is 3. So the series become:
e^x = 1 + x/1! + x^2/2!
So number = 2
terms = 3
series =1
sumSeries = 1
i = 1
The statement series = series * number / (float)i; works as following:
series = 1 * 2 /1
series = 2
sumSeries = sumSeries + series;
sumSeries = 1 + 2
sumSeries = 3
At next iteration: i=2, series =2 , sumSeries =3
series = 2 * 2/2
series = 2
sumSeries = 3 + 2
sumSeries = 5
Now the loop breaks as i=3
So output returns the value of sumSeries i.e. 5
Output:
e^x: 5

Answer: Having the ability to change the source code to fit your needs
Explanation:
Arrays save space because all elements of an array are stored in a single memory location while a list of variables needs a separate location for each variable.
a. True
b. False
Answer:
The correct option is A True
Explanation:
Arrays are implemented to store sevaral variables of the same type as a single array object in java for example. The arrays therefore acts as a container that can store several variables of the same type hence preventing the need to declare those variables seperately thus giving more code efficiency and better storage space management.
The balanced F measure (a.k.a. F1) is defined as the harmonic mean of precision and recall. What is the advantage of using the harmonic mean rather than "averaging" (using the arithmetic mean)?
Answer:
Because the value derived from harmonic mean reflects the credible result of search engine
Explanation:
Given that the value of arithmetic mean tends to be closer to the highest value between Precision and Recall, while the value of the harmonic mean, is the lowest value between Precision and Recall, in a situation where all documents relevant to a query are returned, where R = 1 and P is closer to 0, the arithmetic mean will be greater than 0.5 and will not reflects the credible result of search engine
However, if the harmonic mean is utilized, the value will be closer to the low Precision value, hence it closely reflects the credible result of search engine

Write a program to complete the task given below: Ask the user to enter any 2 numbers in between 1-10 and add both of them to another variable call z. Use z for adding 30 into it and print the final result by using variable results.
Answer:
a = int(input("Enter first value between 1 - 10"))
b = int(input("Enter second value between 1 - 10"))
z = a + b
z += 30
print("The value of z = ", z)
Explanation:
The code is written above in python language to perform the given task.
Now, let us explain each statement of code.
Step 1: The first two lines take input from the user prompting the user to enter the values between 1 to 10.
Then the values are type casted to int using int().
The values are stored in variables a and b.
Step 2: Then, the values of a and b are added to get another variable z.
Step 3: The statement 'z += 30' is equivalent to z = z+30
It adds 30 to the variable z and stores it in the same variable z.
Step 4: Finally the value of variable 'z' is printed using print() command.
The following are types of numbers except one. Select the one which is not an integer.
A. Float
B. Int
C. Long
D. Boolean
Answer:
D) Boolean
Explanation:
Int, Float, Long and Boolean are commonly used data types in programming languages. Of these data types, the Boolean data type, named after George Boole, does not represent a numerical value. Rather it has one of two possible values, True and False. These values represent the two truth values of logic and Boolean algebra.
The Boolean data type is basically associated with conditional statements which specifies different actions to be taken depending on whether the Boolean condition evaluates to true or false. Therefore it influences the control flow of a program.
#We've started a recursive function below called #measure_string that should take in one string parameter, #myStr, and returns its length. However, you may not use #Python's built-in len function. # #Finish our code. We are missing the base case and the #recursive call. # #HINT: Often when we have recursion involving strings, we #want to break down the string to be in its simplest form. #Think about how you could splice a string little by little. #Then think about what your base case might be - what is #the most basic, minimal string you can have in python? # #Hint 2: How can you establish the base case has been #reached without the len() function? #You may not use the built-in 'len()' function.
Answer:
Here is the Python program:
def measure_string(myStr): #function that takes a string as parameter
if myStr == '': #if the string is empty (base case)
return 0 #return 0
else: #if string is not empty
return 1 + measure_string(myStr[0:-1]) #calls function recursively to find the length of the string (recursive case)
#in order to check the working of the above function the following statement is used
print(measure_string("13 characters")) //calls function and passes the string to it and print the output on the screen
Explanation:
The function works as following:
Suppose the string is 13 characters
myStr = "13 characters"
if myStr == '': this is the base case and this does not evaluate to true because myStr is not empty. This is basically the alternate of
if len(myStr) == 0: but we are not supposed to use len function here so we use if myStr == '' instead.
So the program control moves to the else part
return 1 + measure_string(myStr[0:-1]) this statement is a recursive call to the function measure_string.
myStr[0:-1] in the statement is a slice list that starts from the first character of the myStr string (at 0 index) to the last character of the string (-1 index)
This statement can also be written as:
return 1 + measure_string(myStr[1:])
or
return 1 + measure_string(myStr[:-1]) This statement start from 1st character and ends at last character
This statement keeps calling measure_string until the myStr is empty. The method gets each character using a slice and maintains a count by adding 1 each time this statement is returned.The function breaks string into its first character [0:] and all the rest characters [:-1]. and recursively counts the number of character occurrences and add 1. So there are 13 characters in the example string. So the output is:
13

Fill in the gaps in the nametag function so that it uses the format method to return first_name and the first initial of last_name followed by a period. For example, nametag("Jane", "Smith") should return "Jane S."
def nametag(first_name, last_name):
return("___.".format(___))
print(nametag("Jane", "Smith"))
# Should display "Jane S."
print(nametag("Francesco", "Rinaldi"))
# Should display "Francesco R."
print(nametag("Jean-Luc", "Grand-Pierre"))
# Should display "Jean-Luc G."
Answer:
def nametag(first_name, last_name):
return("{} {[0]}.".format(first_name, last_name))
print(nametag("Jane", "Smith"))
# Should display "Jane S."
print(nametag("Francesco", "Rinaldi"))
# Should display "Francesco R."
print(nametag("Jean-Luc", "Grand-Pierre"))
# Should display "Jean-Luc G."
Explanation:
First you must think about that the question ask about the first letter for last_name, remember [0] is the first letter not [1], the other part is about format function and its order
The format method to return first_name and the first initial of last_name followed by a period in python is represented as follows:
def nametag(first_name, last_name):
return '{} {}.'.format(first_name, last_name[0])
print(nametag("Jane", "Smith"))
print(nametag("Francesco", "Rinaldi"))
print(nametag("Jean-Luc", "Grand-Pierre"))
A function named nametag is declared with the arguments first_name and last_name.
Then it returns the first name and the initial of the last_name using the .format method.
Then we call the function using the print statement with the arguments.

Vector testGrades contains NUM_VALS test scores. Write a for loop that sets sumExtra to the total extra credit received. Full credit is 100, so anything over 100 is extra credit. Ex: If testGrades = {101, 83, 107, 90}, then sumExtra = 8, because 1 + 0 + 7 + 0 is 8.
Answer:
Here is for loop that sets sumExtra to the total extra credit received. I am writing a program in C++
for(i = 0; i <= testGrades.size() - 1; i++){
if(testGrades.at(i) > 100){
sumExtra = sumExtra + (testGrades.at(i) - 100); } }
Explanation:
The complete program is:
#include <iostream> //to use input output functions
#include <vector> //to use vectors
using namespace std; //to identify objects like cin cout
int main() { //start of main function
const int NUM_VALS = 4; // sets the value of NUM_VALS as a constant to 4
vector<int> testGrades(NUM_VALS); // initialize the vector of int (integer) type
int i = 0; // i is initialzed to 0
int sumExtra = 0; //stores the total extra credit
testGrades.at(0) = 101; //sets 101 at first position in vector
testGrades.at(1) = 83; //sets value 83 at second position
testGrades.at(2) = 107; //sets value 107 at third position
testGrades.at(3) = 90; //sets value 90 at fourth position
for(i = 0; i <= testGrades.size() -1; i++){ //loop iterate through each value of in a vector testGrades
if(testGrades.at(i) > 100){ // if the value in a vector exceeds 100
sumExtra = sumExtra + (testGrades.at(i) - 100); } } //computes total extra credit
cout << "sumExtra: " << sumExtra << endl;} //displays the value of computed total extra credit in output
The loop works as follows:
In the first iteration the value of vector testGrades at(i) is at(0) = 101.
if statement checks if this value/element is greater than 100. This is true as 101 > 100. So sumExtra = sumExtra + (testGrades.at(i) - 100); statement is executed in which 100 is subtracted from that element and the result is added to the sumExtra. sumExtra is initialized to 0 so the value of sumExtra becomes: 0+ 101 - 100= 1 So the value of sumExtra = 1
In the second iteration the value of i = 1 and it is positioned at 2nd value of vector testGrades i.e. 83. Then if statement checks if this value/element is greater than 100. This is false as 83 < 100. So the value of sumExtra = 1
In the third iteration the value of i = 2 and it is positioned at 3rd value of vector testGrades i.e. 107. Then if statement checks if this value/element is greater than 100. This is true as 107 > 100.
sumExtra = sumExtra + (testGrades.at(i) - 100); statement is executed in which 100 is subtracted from that element and the result is added to the sumExtra
sumExtra is 1 so the value of sumExtra becomes: 1+ 107 - 100= 8 So the value of sumExtra = 8
In fourth iteration the value of i = 3 and it is positioned at 4th value of testGrades vector i.e. 90. Then the if statement checks if this element is greater than 100. This is false as 90 < 100. So the value of sumExtra remains 8.
Finally the loop breaks as the value of i becomes 4. So the output is 8.
Answer:
sumExtra = 0;
for (i = 0; i < NUM_VALS; ++i) {
if (testGrades[i] >= 101) {
sumExtra += (testGrades[i] - 100);
}
}
cout << "sumExtra: " << sumExtra << endl;

The figure below shows a black and white image with a resolution of 720×504. Identify how much memory (in bits) will be occupied by this image in the hard drive of your computer, if it is stored. (2 marks)
Answer:
362880
Explanation:
In black and white images each pixel is 1 bit. You need to first find the total number of pixels, to do this you multiply the width and length of the picture (720x504) and you will get 362880. From there you would multiply the amount of pixels by how many bits each pixel is. In this case, since its black and white you multiply it by 1, which is 362880.
