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.

teamDolphins = 500;
}
Explanation:
Here is the complete program:
#include //to use input output functions
using namespace std; //to identify objects like cin cout
class GamePoints { //class GamePoints
public: GamePoints(); // constructor of GamePoints class
void Start() const; //method of GamePoints class
private: //declare data members of GamePoints class
int teamDolphins; // integer type private member variable of GamePoints
int teamLions; }; // integer type private member variable of GamePoints
GamePoints::GamePoints() //constructor
{ teamLions = (500), teamDolphins= (500); } //assigns 500 to the data members of teamLions and teamDolphins of GamePoints class
void GamePoints::Start() const { //method Start of classs GamePoints
cout << "Game started: Dolphins " << teamDolphins << " - " << teamLions << " Lions" << endl; } //displays the values of teamDolphins and teamLions i.e. 500 assigned by the constructor
int main() //start of main() function
{ GamePoints myGame; // creates an object of GamePoints class
myGame.Start(); //calls Start method of GamePoints class using the object
return 0; }

Which of the following code segments will display all of the lines in the file object named infile, assuming that it has successfully been opened for reading?
a. while line in infile :
print(line)
b. while infile in line :
print(line)
c.for infile in line :
print(line)
d. for line in infile :
print(line)
Answer:
d.
for line in infile :
print(line)
Explanation:
for loop is used to iterate through the each line of the file using line variable. The file is accessed using the object infile. For example if the file name is "file.txt" and it is opened in read mode. It contains the following lines:
hi there friend
how are you
what are you doing
Then the above given chunk of code gives the following output
hi there friend
how are you
what are you doing
At each iteration each line of the the file is printed on the output screen. The print() method is used to display these lines in output.
When enabling IPsec mobile client support, you made some selections in the Xauth section of the interface. What does Xauth stand for
Answer:
Extended authentication
Explanation:
Xauth = Extended authentication
An extended authentication can cause security to be increased because it requires the user to enter a username and password. These details would then be authenticated at the internal database of the controller. This extension is an ipsec extension which would enable VPN users to enter a username and password. These details would be required of the user while trying to connect and they would be checked against the login details registered by such a user.
Would two bits be enough to assign a unique binary number to each vowel in the English language? Explain.
Answer:
No.
Explanation:
Since there are 5 vowels, you'd need at least 3 bits to number them. 2 bits give you 2²=4 possibilities, which is 1 short. 3 bits give you 2³=8 possibilities, which fits 5 easily.
The term "bit" means binary digit, and it is used to represent data in a computer system.
The number of character an n-bit computer can hold is [tex]2^n[/tex]
So, a 2-bit computer can hold a maximum of:
[tex]Max = 2^2[/tex]
[tex]Max = 4[/tex]
i.e. A 2-bit computer can hold a maximum of 4 characters.
The English language vowel are 5 (i.e. letters a, e, i, o and u).
5 is greater than the maximum number of characters the 2-bit computer can hold (i.e. 5 > 4)
Hence, two bits will not be enough to hold each vowel in the English language.

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.
Write a function called count_occurrences that takes two strings. The second string should only be one character long. The function should return how many times the second string occurs in the first string.
Answer:
Here is the Python function:
def count_occurrences (string1 , string2): # method that takes two strings as parameter and returns how many times second string occurs in first
count = 0 #counts number of occurrence of string2 in string1
for word in string1: #iterates through each word of the string1
for character in word: #iterates through each character of each word in string1
if character == string2: # checks if the character in string1 is equal to the character of string2
count = count + 1 #adds 1 to the count of string2 in string1
return count #returns number of times the string2 occurs in string1
#in order to check the working of the function add the following lines to the code:
first_str = input("Enter the first string: ") #prompts user to enter first string
second_str = input("Enter the second string (one character long): ") #prompts user to enter second string which should be one character long
occurrence = count_occurrences(first_str,second_str) #calls count_occurrences method by passing both strings to it
print(second_str,"occurs",occurrence,"times in",first_str) #prints how many times the second_str occurs in the first_str on output screen
Explanation:
The program is well explained in the comments added to each statement of the above code. I will explain the program with an example:
Suppose
string1 = "hello world"
string2 = 'l'
So the method count_occurrences() should return how many times l occurs in hello world.
count is used to count the number of occurrences of l in hello world. It is initialized to 0.
The first loop iterates through each word of string1. The first word of string1 is "hello"
The second loop iterates through each character/letter of each word. So the first letter of "hello" word is 'h'.
The if condition if character == string2: checks if the character is equal to string2 i.e. l.
character = "h"
string2 = "l"
The are not equal so the program moves to the next character of word hello which is e. The if condition again evaluates to false because e is not equal to l. So the program moves to the next character of word hello which is l.
This time the if condition evaluates to true because
character = "l"
string2 = "l"
character == string2
l == l
So the if part is executed which has the following statement:
count = count + 1
So the count is added to 1. count was 0 previously. Now
count = 1
Next the program moves to the next character of word hello which is l. This time the if condition evaluates to true because the character l matches with string2. So count is again incremented to 1. count = 2.
Next the program moves to the next character of word hello which is o. The if condition evaluates to false as o does not match with string2 i.e. l. So the count remains 2.
Next the first loop moves to the next word of the string1 = "world". The inner (second) for loop iterates through each character of "world" from "w" to "d" and checks if any character is equal to string2. Only one character is equal to string2 in "world". So count is incremented to 1. Hence count = 3
After the loop ends the statement return count returns the number of times string2 occurs in the string1. So the output is:
l occurs 3 times in hello world
Answer:
def count_occurrences(sentence, thing_to_count):
times = 0
for word in sentence:
for letter in word:
if letter == thing_to_count: times += 1
return times

Which statement correctly creates a set named colors that contains the 7 colors in a rainbow?
a. colors = ["red", "orange", "yellow" "green", "blue", "indigo", "violet"]
b. colors = {red, orange, yellow, green, blue, indigo, violet}
c. colors = [red, orange, yellow, green, blue, indigo, violet]
d. colors = {"red", "orange", "yellow", "green", "blue", "indigo", "violet"}
Answer: d. colors = {"red", "orange", "yellow", "green", "blue", "indigo", "violet"}
Explanation:
We use "{}" to write a set in it.
Also, the names of the colors are strings so we use inverted commas ("") to express them.
So, the set named colors that contains the 7 colors in a rainbow will be:
colors = {"red", "orange", "yellow", "green", "blue", "indigo", "violet"}
Hence, the correct option is d.

Outline a scenario in which you might be acting ethically but might still want to remain anonymous while using the Internet. How might someone learn your identity even if you attempt to remain anonymous?
Answer:
I would like to stay anonymous while criticizing the current government. As there have been many cases when people who wrote against the government's decisions were caught by the police.
So I would prefer to stay anonymous while commenting on various government policies. My friends would know about it because I share my posts only with them.
The government can know about my identity by ordering the social networking site to reveal it.
One scenario in which you can act ethically but still remain anonymous when using the internet could be to guarantee your freedom of expression on a certain subject, sharing your ideas in the way you think is ideal for the situation.
Is anonymity on the internet legal?It is protected by the US Supreme Court under the First Amendment, but its protection is balanced, that is, anonymity on the internet can be dissolved and the user can be found if the use of this function occurs to commit cyber crimes.
Therefore, it is essential that every individual action on the internet and outside of it is based on ethics and legality, so that there is an orderly and positive society for all citizens.
