Course: C Programming

Welcome to the C Constants Quiz.

This quiz checks your understanding of constants in the C programming language, which are fixed values that do not change during program execution. Constants help make programs more readable, reliable, and easier to maintain by preventing accidental value changes. In C, constants can be created using the const keyword, #define preprocessor directives, or as literal values directly in code. Knowing when and how to use constants is an important part of writing clean and well-structured C programs. Read the instructions carefully before starting the quiz.
