简单的比较两个数的大小，记得类型定得大一点

#include<stdio.h>
#include<string.h>
int main()
{
 long long a,b;
 int i;
 while(scanf("%d",&i)!=EOF)
     {
      while(i--)
           {
            scanf("%lld%lld",&a,&b);
            if(a>b)
              printf(">\n");
            else if(a<b)
              printf("<\n");
            else
              printf("=\n");
           }
     }
 return 0;
}
