PF: Q2 -Iterative Structures IT1104

What is the primary purpose of iterative structures in programming?

• To repeat a code block based on conditions

• To create complex data types

• To manage memory allocation

• To define functions

Which loop type evaluates the condition before executing the code block?

• for loop

• do...while loop

• while loop

• foreach loop

What is guaranteed by the do...while loop?

• The loop will execute indefinitely

• The loop will never execute

• The code block is executed only if the condition is true

• The code block is executed at least once

In a for loop, which part is executed only once at the beginning?

• Increment

• Condition

• Code block

• Initialization

What happens if the condition of a while loop is false initially?

• The code block executes multiple times

• The code block is never executed

• The loop runs indefinitely

• The code block executes once

Which of the following is NOT a type of loop in C?

• for loop

• do...while loop

• repeat...until loop

• while loop

What is the role of loops in programming?

• To create user interfaces

• To automate repetitive tasks

• To handle exceptions

• To define data structures

Which loop type is best suited for a scenario where the code block must execute at least once?

• for loop

• nested loop

• while loop

• do...while loop

What is the correct order of execution in a for loop?

• Code block, Condition, Initialization

• Initialization, Condition, Increment

• Initialization, Code block, Condition

• Condition, Increment, Code block

Why are iterative structures considered fundamental building blocks in programming?

• They enable code repetition based on conditions

• They allow for data storage

• They define the structure of a program

• They are used for error handling
