  本来想发表两句,唉,有人悲愤了,算了,闭口,不发言了,

  #include <stdio.h>
void main()
{
int n;
printf("please input :");
scanf("%d",&n);           
switch(n)
{case 1:if("85<n<=100")
   printf("A");break;
case 2:if("70<n<=85")
   printf("B");break;
case 3:if("60<n<=70")
   printf("C");break;
case 4:if("n<=60")
   printf("D");break;
default:printf("error\n");
}
}
怎么总是出现error呢

  这个库函数怎么了
你的楼上弄错了。实际上下面两种写法都是OK的:
1。#include <stdio.h>
2。#include  "stdio.h"
