Header files in C serve as a way to declare the structure of functions and variables before they are used in a program. They provide a way to organize code, promote reusability, and facilitate modular programming. By including header files, you can declare functions and variables without defining their actual implementation, allowing you to use them across multiple source files. Commonly used header files include <stdio.h> for input/output operations and <stdlib.h> for memory allocation functions, among others. read less
