Need clarity on below program,

What will the below program print? 

#include <iostream> 
using namespace std;    

static int x = 10;

void main1()    
{      
    cout << x << endl;    
    x = x + 1;    
}    

int main()   
{    
    main1();    
    main1();        
    cout << x << endl;    
}

As per my understanding, the above program we used static variable, so x retains the last initialized variable. So the output will be 

10    
11    
12

but if we removed static, we should get 

10    
10    
10

but I am getting the below output, even after removing static.

10    
11    
12

Please help me to understand.

the static keyword has several meanings in C depending on where yoi use it. Read this http://msdn.microsoft.com/en-us/library/s1sb61xd(v=vs.80).aspx

Since x is global visible to both main1 and main it will not make difference whether static is there or not.

Even if int x is not static, it is still a global variable, outside the scope of main and main1.

Thus whatever change you make to x from anywhere inside this file is going to change it permanently.
