请问一下这个编程怎么错了呢？我找不出原因哦。请求帮忙.

  

  printf("%d %s %s %s %d\n", ststud[i].iId, ststud[i].chName,
            ststud[i].chSex, ststud[i].chdizhi,ststud[i].fsore[j]);
最好把几个输入项分开处理，你这样容易出问题

printf("%d %s %s %s %d\n", ststud[i].iId, ststud[i].chName,
            ststud[i].chSex, ststud[i].chdizhi,ststud[i].fsore[j]);

ststud[i].chSex是一个插入类型的字符，不能用%s来打印，
用%c，其他地方还没看，你先试试吧
