改好了，错的地方太多了，干脆直接给你代码，你自己对比一下

#include"stdio.h"
#include"math.h"
main()
{
    int m,n,i,h=0,leap=1;
    printf("\n");
    for(m=101;m<=200;m++)
    {
        n=sqrt(m+1);
        for(i=2;i<=n;i++)
        {
            if(m%n==0)
            {
                leap=0;
                break;
            }
            if(leap)
            {
                printf("%4d",m);
              h++;
              if(h%10==0)
            {
               printf("\n");
            }
        }
        leap=1;
        }
       
    }
    printf("\nthe total is %d",h);

}

少了个大括号！而且){printf("%_4d",m);
这个格式也错了！

额！比版主大人慢了一步

if(leap){printf("%_4d",m);输出能有空隔吗？

应该是对i求余，功能是输出101到200所有素数．每输出十个素数换行．

谢谢各位的光临 ！！！！呵呵
