Questions & Answers

Q: What is the syntax of the do while loop in C?

The syntax consists of the keyword "do," a set of statements enclosed in braces, followed by the condition in parentheses and a semicolon.

Q: How does the behavior of the do while loop differ from while and for loops?

The do while loop executes its statements at least once before checking the condition, unlike while and for loops that may not run if the condition is initially false.

Q: Can a do while loop have only one line of code without braces?

Yes, it is possible to have a single line of code in a do while loop without braces, but it is recommended to use braces for clarity and consistency.

Q: Why is the do while loop guaranteed to run at least once?

The nature of the do while loop ensures that the statements are executed before the condition is checked, making it a unique feature compared to other loop types.
