Understanding Header Files in C: Importance & Usage Explained!

A header file in C is a file with a .h extension that contains function declarations, macros, and type definitions, allowing code reusability and better organization.
It is included in a .c file using #include to access functions and constants defined elsewhere, reducing redundancy. Standard headers like stdio.h and stdlib.h provide built-in functionality, while custom headers help modularize large programs. Proper use of header files enhances code maintainability and efficiency in C programming.
