C Programming Quiz Instructions

Welcome to the C While Loop Quiz.

This quiz tests your understanding of the while loop in C, which is used to execute a block of code repeatedly as long as a specified condition remains true. The while loop is one of the most commonly used looping constructs in C and is especially useful when the number of iterations is not known in advance. It helps automate repetitive tasks, process data continuously, and build efficient programs. Learning how to use while loops correctly allows you to control program flow and avoid unnecessary repetition in code. Read the instructions carefully before you begin the quiz.
