What is the difference between while and do-while loops in C?

a) do-while executes the loop body at least once, while may not
b) while executes the loop body at least once, do-while may not
c) Both execute the loop body the same way
d) while is used for infinite loops, do-while is not

Answer:

a) do-while executes the loop body at least once, while may not

Explanation:

The primary difference between while and do-while loops in C is that the while loop checks the condition before executing the loop body, meaning the loop body may not execute at all if the condition is false initially. In contrast, the do-while loop checks the condition after executing the loop body, ensuring that the loop body is executed at least once, regardless of the condition. This makes do-while useful when you need the loop body to execute at least once before checking the condition.

Understanding the difference between while and do-while loops is important for choosing the right loop structure based on the specific requirements of the task.
