What is function :-
Function is a group of statement or instructions that are written with a purpose to perform a certain task whenever it is require.
Their are two type of function use in c programming-
1)Built-in function
2) user defined function
1)Built-in function:-
built-in function in c are provided with c -package and the definition of there function are already define and stored in c-library. The declaration of these building functions are given in header (.h) files.
2)User define function:-
These function are defined by the programmer for specific purpose to used in his program.
Example:- If you want to make a function 'sum' for adding two numbers then the syntax of this function is :-
Advantage of using function :-
(i) Modular programming :-
It is a programming paradigm that breaks down the bigger problem into smaller subproblem. these subproblem are solved separately and their solution are combined to solve the bigger problem.
(v)Facilitates reuse ability of codes.
