不知道哪裡出錯了，請大神提示下，看了好久了，感覺是括號的問題，但不知道怎麼改

#include<stdio.h>
#include<time.h>
#include<stdlib.h>
main()
{
    int rollDice();
    void delay();
    int i,result = 0 ,result1 = 0;
    printf("Game Start!!!!\n");
    result = rollDice();
    printf("%d\n",result);
    delay();
    if ((result == 7 )||(result == 11))
        {printf("Y\n");break;}
    else if ((result == 2) || (result == 3)|| (result == 12))
        {printf("N\n");}
    else
        printf("C\n");
        for (i = 0;i<7;i++)
            {result1 = rollDice();
            printf("%d\n",result1);
            if (result1==result)
                {printf("Y\n");break;}
            else if ((result1!=result)&&(i==6))
                printf("N\n");
        }
    return 0;
}
int rollDice()
{
     void delay();
     int a,b,c;
         srand((unsigned)time(NULL));
         a= rand()%6 + 1;
         delay();
         b= rand()%6 + 1;
         c = a + b;
     return c;
}
void delay()
{
    long t;
    for (t=0;t<50000000;t++)
    {

    }
}
