Inline function: 

A function which can be expended in line is called an inline function. it's help in reducing the function call overhead.

to make a function inline you just need to add the inline keyword at the beginning of the definition of the function.

                inline int squre(int a)

                  return a*a;

Note: in the inline function, there is only one line of code. like you see in the above example.

the inline function advises the compiler to generate a copy of the function's body code in every place where the function is called.
typically inline function placed in the header section of the program.

Example c++ program using an inline function 

              #include <iostream>

              inline squre(int a)
                return a*a;     // inline function is alway one line of code in body section.

              int main()

                int x;
                std::cout<<"\n enter the value of x:";


                return 0;


so, I think now you understand what is the inline function, and how to use it in programming.
