Questions

1. What is the purpose of control structures in programming?
Answer: To control the flow of execution
Explanation: Control structures are used to control the order in which statements are executed in a program.Report for correction
2. Which control structure is used to execute a block of code repeatedly while a condition is true?
Answer: for loop
Explanation: A for loop is used for repetitive execution based on a condition.Report for correction
3. In a while loop, how is the loop condition checked?
Answer: Before entering the loop
Explanation: In a while loop, the condition is checked before entering the loop.Report for correction
4. What is the purpose of an if-else statement?
Answer: To make decisions based on a condition
Explanation: An if-else statement is used to make decisions based on a condition.Report for correction
5. Which logical operator represents "AND" in most programming languages?
Answer: AND
Explanation: The logical operator "AND" is typically represented as "&&" in many programming languages.Report for correction
6. In a switch statement, what happens if no case matches the provided value?
Answer: The default case is executed (if present)
Explanation: In a switch statement, if no case matches, the default case (if present) is executed.Report for correction
7. What does the "break" statement do in a loop or switch statement?
Answer: Terminates the loop or switch statement
Explanation: The "break" statement is used to exit a loop or switch statement.Report for correction
8. What is the result of the expression (5 > 3) && (7 < 10)?
Answer: true
Explanation: Both conditions are true, so the result is true.Report for correction
9. In a do-while loop, when is the loop condition checked?
Answer: After executing the loop
Explanation: In a do-while loop, the condition is checked after executing the loop.Report for correction
10. What is the purpose of the "else if" statement in control structures?
Answer: To provide an alternative condition to check
Explanation: The "else if" statement is used to provide an alternative condition to check when the previous condition is false.Report for correction
11. Which of the following is not a control structure in programming?
Answer: data type declaration
Explanation: Data type declaration is not a control structure; it's used to define the type of data a variable can hold.Report for correction
12. What is the result of the expression (4 + 6 * 2) / 3?
Answer: 10
Explanation: The expression is evaluated as (4 + 12) / 3 = 16 / 3 = 10.Report for correction
13. In a switch statement, what is the purpose of the "break" statement?
Answer: To exit the switch statement
Explanation: The "break" statement is used to exit the switch statement after a case is matched.Report for correction
14. Which operator is used to represent "OR" in most programming languages?
Answer: OR
Explanation: The logical operator "OR" is typically represented as ",," in many programming languages.Report for correction
15. What is the purpose of a "try-catch" block in programming?
Answer: To handle exceptions and errors
Explanation: A "try-catch" block is used to handle exceptions and errors that may occur during program execution.Report for correction
16. Which control structure allows a program to perform different actions based on different conditions?
Answer: switch statement
Explanation: A switch statement allows a program to perform different actions based on different conditions.Report for correction
17. What does the "continue" statement do in a loop?
Answer: Skips the current iteration and continues to the next
Explanation: The "continue" statement is used to skip the current iteration and continue to the next iteration of the loop.Report for correction
18. Which logical operator represents "NOT" in most programming languages?
Answer: NOT
Explanation: The logical operator "NOT" is typically represented as "!" in many programming languages.Report for correction
19. In an if-else statement, what happens if none of the conditions are true and there is no "else" block?
Answer: Nothing happens; execution continues
Explanation: If none of the conditions in an if-else statement are true and there is no "else" block, execution continues with the next statement after the if-else block.Report for correction
20. What is the purpose of the "default" case in a switch statement?
Answer: To execute when none of the other cases match
Explanation: The "default" case in a switch statement is executed when none of the other cases match.Report for correction
21. Which control structure is used to create a loop that repeats indefinitely until a certain condition is met?
Answer: while loop
Explanation: A while loop is used to create a loop that repeats until a certain condition is met.Report for correction
22. In a for loop, which part of the loop controls the iteration count?
Answer: The increment expression
Explanation: In a for loop, the increment expression controls the iteration count.Report for correction
23. What is the purpose of the "else" block in an if-else statement?
Answer: To execute when the condition is true
Explanation: The "else" block in an if-else statement is executed when the condition is false.Report for correction
24. What is the result of the expression (10 % 3)?
Answer: 1
Explanation: The expression (10 % 3) returns the remainder of the division, which is 1.Report for correction
25. What is the purpose of the "if" statement in control structures?
Answer: To make decisions based on a condition
Explanation: The "if" statement is used to make decisions based on a condition in control structures.Report for correction
