How does this work?

#include <stdio.h>

int main ()
{
    int c, d;

    d = EOF;

    while ((c = getchar()) != EOF){
        if (c == ' ')
            if (c != d)
                putchar(' ');
        else
            putchar(c);
    }
}

Here's an idea:

#include <stdio.h>
int main(void) { int c; while ((c = getchar()) != EOF) putchar(c); return 0; }

It does the same thing.
