Can you know about the Functions in a Programming Language like User-Defined and Inbuilt Functions?

Functions -: Function is used to divide the programs means to divide your logics into parts and define each logic into appropriate parts.

Functions are two types -: 

1.  Inbuilt functions 
2.  User-defined functions

Inbuilt Functions -: Those functions that are already defined in a programming language like print function, etc.

User-Defined Functions -: Those functions are defined by the user according to their needs or logic.

Examples -: 

    1. Inbuilt Function -: Take an example of inbuilt function 'printf' in C                                             programming language that is used to print.   Example  'printf' is the inbuilt function in a C programming language.

2. User-Defined Function -: User-Defined functions syntax is depend on the programming language.

To define a User-Defined Functions in C are -: 

return_type function_name(parameter list) {

//statement

}
