Yes, in C, the #include directive is used to include header files that provide declarations and functions your program can use. For example:

c #include <stdio.h> // For standard input/output functions #include "myheader.h" // For user-defined headers (use quotes for custom files)

Use < > for standard library headers and " " for user-defined ones. Ensure header files include guards (or #pragma once) to prevent multiple inclusions.
