Static in C++

What is Static in C++?

Ans: I believe that Examples are the best way to make someone understand so:

#include <iostream>

using namespace std;

f1();

void main()

{

f1();

f1();

}

f1()

{

static int s = 0;

cout << s++ << endl;

}

The value of 's' does not start from 0 when the function is called second time, rather it starts from last value of of s when function was called last time (i.e. 1 in this case when Function is called second Time).
