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 order to not discourage the user, error messages must be implemented in a user-friendly way with the use of strategies which ensure coordination, consistency and simplicity.

Error messages should be short, direct and communicate clearly, the right amount of information to a user. These messages should be sorted into categories which represent different kinds of errors. These specific categories should have a brief alphanumeric code that can be easily shared with a customer support personnel for solution and also to help users search for solutions themselves, on the internet.

e. /Users/me/Documents/file.txt

The Python statement is an illustration of file manipulations

The output from the Python statement is: (e) /Users/me/Documents/file.txt

From the given statement, the first line imports the Python os module.

While the second line gets the current working file path.

So, the statement os.path.join(cwd, 'Documents/file.txt') means that:

The current working file path is Documents/file.txt

Hence, the output from the Python statement is: (e) /Users/me/Documents/file.txt

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.

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;

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

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

int factorial(int number)  {  

   if (number == 0)  

       return 1;  

   return number * factorial(number - 1);  }    

int main()  {  

   int integer;

   cout<<"Enter a non negative integer: ";

   cin>>integer;

   cout<< "Factorial of "<< integer<<" is "<< factorial(integer)<< endl;  }

Python:

def factorial(number):  

   if number == 0:  

       return 1

   return number * factorial(number-1)  

integer = int(input("Enter a non negative integer: "))  

print("Factorial of", integer, "is", factorial(integer))

b)

C++

#include <iostream>  

using namespace std;

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:

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.
