Not getting output from counting getchar() blanks

Code:

---

#include "stdafx.h"
#include <cstdio>

using namespace System;

int main(array<System::String ^> ^args)
{
    int c, nl;
       

        nl = 0;
        while ((c = getchar()) != EOF)
                if(c == ' ')
                        nl++;
                       

                printf("The number of blanks is %d\n", nl);
       

    return 0;
}

---

I'm trying to count the number of blank (" ") spaces from user input using getchar(), then outputting the value using printf. But no output is done after I put in characters into the program. Any suggestions?

One suggestion would be to actually write it in C, not the brain-damage of M$ "managed" C++.

The other is when you're typing away at your console, to actually generate an EOF signal, you press ctrl-z (as the first 'character' on any input line).
