C 655 not golfed

Code creates weighted sum of chars for each string. If the difference is zero then they are equal, including 2 empty strings:

    #include <stdio.h>
#define N 100
#define P(x) printf(x)
#define G(x) gets_s(x)

void e(int x){ x ? P("equal\n") : P("not equal\n"); }
int main()
{
    char s[N], t[N];//words
    char *p = 0, *q = 0;
    int r = 0; //result 0=false
    int n=0, m=0; //weighted sums
    int i = 1; //char pos start at 1
    if ((p=gets_s(s)) &&
        (q=gets_s(t)))
    {
        while (*p)
        {
            n += i*(int)*p;
            m += i*(int)*q;
            i++;
            p++;
            q++;
            if (!(*q)){
                break;
            }
        }

        if (!*p && !*q){ //both same length strings
            if (!(m - n)){ r = 1; } //weighted sums are equal           
        }//else r=0, false=>not equal

        e(r);
    }
    else{
        P("error\n");
    }
    getchar();
}

Note: Visual Studio complains if you don't use their safe methods eg gets_s. CodeBlocks with mingw compiles without warnings.
