Header Files In C Language

In this tutorial we learn more about header files, how to create our own custom header files and why we use then in our codes.

Learn about C header files, their purpose, and how to use them effectively in your C programming projects.

The C language is famous for its various libraries and predefined functions pre-written within it. These make the programmer's effort a lot easier. In this tutorial, you will learn about C header files, how it works in the C language and how you can include them in your C program.

In this tutorial we will learn about header files in C. Why we use header files in C programs, how header files work and different types of header files in C.

In C programming, a header file is a file that ends with the .h extension and contains features like functions, data types, macros, etc that can be used by any other C program by including that particular header file using quotincludequot preprocessor. C language uses header files to provide the standard libraries and their components for use in programs. Example

To include and start using these functions in any other C file, just include this header file using include quotarith.hquot Note I have assumed that both your main file and header file exists in same directory.
