Could anyone give me a little help?

I'm trying to use recursive programming for getting = a=20 factorial of a number. The source I've made is:

#include <stdio.h>
#include = <stdlib.h>
long=20 int rcs_factorial(long int);

main(){
int num;
printf("Factorial of:=20 ");
scanf("%d",&num);
printf("=20 %ld",rcs_factorial(num));
}

long int rcs_factorial(long int passed){
= if(passed=20 <=3D1 ){
    printf("%d =3D=20 ",passed);
    return 1;
}
=20 else{
    printf("%d *=20 ",passed);
    return passed *=20 rcs_factorial(--passed);
}
}

But it doesn't work. It does the rigth number of = calls to=20 rcs_factorial but fails at doing the first multiplication.

Thanks.

Luis.
