I have this program and I am trying to output the value of n, but I am not getting any display. Program complies but no output.

    #include <stdio.h>

int rec(int x, int y)
{
    static int count = 0;
        if(x==0)
            return count;
            count++;
        if(x > y)
            rec(x - y, y);
        else
            rec(x,y-x);
        return count;
}

main(){
    int i=0, j=2, n;
        n = rec(i,j);
        printf("%d", n);
}

Need the value of N as output, program doesn't display anything.

    When I ran it it output 0. Are you sure that's the code you're actually running? Commented Apr 14, 2014 at 0:52

Are you sure it doesn't? You do not output a newline, so it would be smushed against the next command line prompt, so it's kind of easy to miss.
