此程序实现的是200以内的随机整数的四则运算

代码：

#include<iostream.h>
#include<stdlib.h>
int main()
{
        int i,a,b,c,k;
        for (i=0;i<=29;i++)
       {
             a=rand()%200;
             b=rand()%200;
             if(b>a)
             {
                  c=a;
                  a=b;
                  b=c;
              }
              k=rand()%4;
              if(k==0)
                   cout<<a<<"+"<<b<<"="<<endl;
              if(k==1)
                   cout<<a<<"-"<<b<<"="<<endl;
              if(k==2)
                   cout<<a<<"*"<<b<<"="<<endl;
              if(k==3)
                   cout<<a<<"/"<<b<<"="<<endl;
        }
        return 0;
}
