inline c 2b 2b

1#include<iostream>
2/* When a function will be called repetitively, The "inline" keyword is used for 
3optimization. The inline function tells the compiler that every instance of
4this function should be replaced with the line or block of code in the body of the function;
5This makes the compiler skip the middle-man, the function itself!
6
7Important note: this method of optimization saves very little space, but it is still good practice.

1Inline Member Functions (C++)
2A member function that is both declared and defined in the class member list is called an inline member function. Member functions containing a few lines of code are usually declared inline.
