Types of functions in c

A function in C is a set of statements that when called perform some specific tasks. It is the basic building block of a C program that provides modularity and code reusability.

The programming statements of a function are enclosed within { } braces, having certain meanings and performing certain operations.

Syntax of function in c

They are also called subroutines or procedures in other languages.

In this article, we will learn about functions, function definition. declaration, arguments and parameters, return values, and many more.

Syntax of Functions in C

The syntax of function can be divided into 3 aspects:

1. Function Declaration
2. Function Definition
3. Function Calls

Function Declarations

In a function declaration, we must provide the function name, its return type, and the number and type of its parameters.

A function declaration tells the compiler that there is a function with the given name defined somewhere else in the program.

Syntax

return_type name_of_the_function (parameter_1, parameter_2);

The parameter name is not mandatory while declaring f
