Thread: Stuck on a game of craps in C

This is homework, i have the code mostly complete but am receiving a compile error that I can not figure out. any help would be appreciated. the error at compile is E2379 line 39

Code:

#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <string.h>
 
int main ()
{
    int i,d1,d2,sumd,sumd2;
    double winf = 0, lossf = 0, winp = 0, lossp = 0;
    printf("This program will simulate the game of craps for 100 times.\n");
 
    for (i=0; i<100; i++) 
    {
        d1 = rand()%6+1;
        d2 = rand()%6+1;
        sumd = d1 + d2;
 
        if (sumd==7 || sumd==11) 
        {
            winf++;
        }
        if (sumd==2 || sumd==3 || sumd==12) {
            lossf++;
        }
        if (sumd==4 || sumd==5 || sumd==6 || sumd==8 || sumd==9 || sumd==10) {
            while (1) 
            {
                d1 = rand()%6+1;
                d2 = rand()%6+1;
                sumd2 = d1 + d2;
 
                if (sumd2>=sumd)
                { 
                    printf("Win by points.\n");
                    winp++;
                    break;
                }
                else ((d1==7) || (d2==7))
                { 
                    printf("You rolled a 7, you lose.\n");
                    lossp++;
                    break;
                }
            }
        }
    }
 
    printf("First roll wins: %lf\n", winf);
    printf("First roll losses: %lf\n", lossf);
    printf("Points wins: %lf\n", winp);
    printf("Points losses: %lf\n", lossp);
    
return 0;
