In programming, a big task is divided into smaller ones to enable programmers to develop on a solid foundation that others have done instead of starting over from scratch. In order to do so, function is invented in programming world. Proper functions hide its operation details from the external programs using them and expose only the interface and its usage.
The C has been designed in such a way that make functions easy to use and efficient. A C program typically consists of many small functions. C functions are reside in a separated file and loaded together with the source files of the program. C provides a lot of built-in functions to do various tasks ranging from file I/O, string manipulation, network interface…etc.
In this section, you will find the tutorials on how to create your own function in C.
-
A function is a unit of code that designed to accomplish a particular task.
-
C supports a wide range of mechanisms to allow you to program functions effectively.
-
Recursive function is a function which contains a call to itself. Here you will learn how to implement C recursive function.
