大佬们能看看哪里错了么？一直有4个测试点不过

#include <stdio.h>

int main ( )
{
    int school1,home1,school2,home2,school3,home3,school4,home4,school5,home5,school6,home6,school7,home7;

    if ((school1+home1<=8)&&(school2+home2<=8)&&(school3+home3<=8)&&(school4+home4<=8)&&(school5+home5<=8)&&(school6+home6<=8)&&(school7+home7<=8)){
        printf("0");
    }else if ((school1+home1>=school2+home2)&&(school1+home1>=school3+home3)&&(school1+home1>=school4+home4)&&(school1+home1>=school5+home5)&&(school1+home1>=school6+home6)&&(school1+home1>=school7+home7)){
