Inline function in cpp

#cpp

Inline function :

whenever a function is called it tasks a lot of extra time in executing a series of instruction for task such as

Jumping to the function

2.Saving Register

3.pushing argument into the stack and returning to the calling function

Above task is executed either the function is small or big
So whenever the function is small these task become overhead one solution is use macro and second is that inline function concept
inline when it is invoke. that is the compiler replaces the function call with the corresponding function code.

To make a function Inline

#include <iostream>
using namespace std;
inline int square(int a)
{
    return a*a;
}
int main()
{
    cout << "The square of 2 is: " <<square(2)<<;
    return 0;
}

Reminder:

Remember that the inline keyword sends the request, not a command, to the compiler
The compiler may ignore this request if the function definition is too long & too complicated.
then compiler will treat the function as a normal function.
