Constants in C are fixed values that do not change during the execution of a program. They enhance code readability, maintainability, and reduce errors by replacing magic numbers with meaningful names. C supports various types of constants, including integer, floating-point, character, and string constants. You can define constants using the #define
pre-processor directive or the const
keyword. This tutorial on constants in C explains the syntax, types, and best practices for using constants effectively. Whether you're a beginner or refreshing your knowledge, mastering constants is essential for writing clean, reliable C programs that are easier to debug and maintain.
Learn how constants in C help you write clearer, more reliable, and error-free programs.
