我写了个好麻烦的代码，运行失败找不到原因

#include <stdio.h>
int main()
{
    /* 定义需要计算的日期 */
    int year = 2008;
    int month = 8;
    int day = 8;
     int result;
     int temporary;
switch(year%4)
{
    case 0:
        result+=1;
        if(month>2||month<8);
        {

            if(month%2==0);
            {
                result+=month/2*31+(month/2-1)*30+28;
                printf("result");
            }
            else
            {
                result+=(month/2+1)*31+(month/2-1)30+28;
                printf("result");
            }
        }
        else if(month<2||month>0)
        {
            result+=31;
            printf("result");
        }
        else if(month==2)
        {
            result+=31+28;
             printf("result");
        }
        else if(month>=8)
        {

            month-7=temporary;

            result+=(month/2+1)*31+(month/2-1)30+28;

              if(temporary%2==0)
               {
                result+=temporary/2*31+(temporary/2-1)*30+28;
                 printf("result");
               }
               else
               {
                result+=(temporary/2+1)*31+(temporary/2-1)30+28;
                 printf("result");
               }
        }




    default:
    printf("%s\n"," 我失败了");
