Control Flow and Loops Programming Quiz

1. What is a nested loop?

A loop inside another loop

A loop that repeats infinitely

A loop with multiple conditions

A loop inside a function

2. The continue statement halts program execution immediately.

True

False

3. In an if-else chain, once a condition is true, all remaining conditions are skipped.

True

False

4. The break statement only works inside loops, never in switch statements.

True

False

5. A for-each loop iterates over elements in a collection or array.

True

False

6. The logical AND operator (&&) returns true only if both conditions are true.

True

False

7. An infinite loop occurs when the condition never becomes false.

True

False

8. A do-while loop executes the code block before checking the condition.

True

False

9. What does the ternary operator (? :) do?

Performs a loop

Provides a shorthand for if-else

Declares a variable

Imports a module

10. How many times does this loop execute? for(int i=0; i

4 times

5 times

6 times

Infinitely

11. What does an if-else statement do?

Executes one block if a condition is true, another if false

Repeats a block of code multiple times

Declares a variable for later use

Imports a library or module

12. In a switch statement, what is the purpose of the break keyword?

Exits the switch block

Skips to the next case

Restarts the switch

Defines a new case

13. What does a switch statement do?

Toggles a boolean value

Selects one case to execute based on an expression

Loops through an array

Defines a function

14. Can an if statement have multiple else-if blocks?

No, only one else-if allowed

Yes, as many as needed

Only two else-if blocks

Only in loop contexts

15. What is the correct syntax for a simple if statement?

If (condition) { code }

If condition { code }

If [condition] code

If: condition code

16. Which statement skips the current iteration and moves to the next?

Break

Continue

Skip

Exit

Stop

Break

Return

18. In a for loop, what does the increment expression do?

Initializes the loop variable

Updates the loop variable after each iteration

Checks the loop condition

Breaks the loop

19. What is the primary difference between a for loop and a while loop?

For loops are faster

For loops use a counter; while loops check a condition

While loops cannot iterate

For loops only work with arrays

20. Which loop type executes a block of code while a condition is true?

For loop

While loop

Do-while loop

Foreach loop
