我编译的一部分：
for(i=0;i<5;i++)
{
if(school[i].total_score==a[0]) school[i].rank=1;
if(school[i].total_score==a[1]&&a[1]!=a[0]) school[i].rank=2;
if(school[i].total_score==a[1]&&a[1]==a[0]) school[i].rank=1;
if(school[i].total_score==a[2]&&a[2]!=a[1]) school[i].rank=3;
if(school[i].total_score==a[2]&&a[2]==a[1]&&a[1]==a[0]) school[i].rank=1;
if(school[i].total_score==a[2]&&a[2]==a[1]&&a[1]!=a[o]) school[i].rank=2;
if(school[i].total_score==a[3]&&a[3]!=a[2]) school[i].rank=4;
if(school[i].total_score==a[3]&&a[3]==a[2]&&a[2]!=a[1]&&a[1]!=a[0]) school[i].rank=3;
if(school[i].total_score==a[3]&&a[3]==a[2]&&a[2]==a[1]&&a[1]!=a[0]) school[i].rank=2;
if(school[i].total_score==a[3]&&a[3]==a[2]&&a[2]==a[1]&&a[1]==a[0]) school[i].rank=1;
if(school[i].total_score==a[4]&&a[4]!=a[3]) school[i].rank=5;
if(school[i].total_score==a[4]&&a[4]==a[3]&&a[3]!=a[2]&&a[2]!=a[1]&&a[1]!=a[0]) school[i].rank=4;
if(school[i].total_score==a[4]&&a[4]==a[3]&&a[3]==a[2]&&a[2]!=a[1]&&a[1]!=a[0]) school[i].rank=3;
if(school[i].total_score==a[4]&&a[4]==a[3]&&a[3]==a[2]&&a[2]==a[1]&&a[1]!=a[0]) school[i].rank=2;
if(school[i].total_score==a[4]&&a[4]==a[3]&&a[3]==a[2]&&a[2]==a[1]&&a[1]==a[0]) school[i].rank=4;
}
这几行共同的错误：subscript requires array or pointer type
怎么改呢？
问：挺简单的一C函数，不过我是初学者，暂时还不会写，请好心人多多帮忙！
答：int mystrlen(char *str) { int n = 0; while (*str) { n++; str++;} return n; } voi...详情>>
