0-100的10道四则运算题

#include<iostream>

#include<time.h>

#include<stdio.h>

using namespace std;

void main()

{

int t,num,a,n,i,b;

srand(time(NULL));//根据时间产生随机数

for(i=0;i<10;i++)

{

a=rand()%100;//0-100随机一个数赋值

loop:b=rand()%100;//0-100随机一个数赋值????????

n=rand()%4;

switch(n)

{

case 0:cout<<"第"<<i<<"题"<<endl;

cout<<a<<"+"<<b<<"=";

t=a+b;

break;

case 1:cout<<"第"<<i<<"题"<<endl;

cout<<a<<"-"<<b<<"=";

t=a-b;

break;

case 2:cout<<"第"<<i<<"题"<<endl;

cout<<a<<"*"<<b<<"=";

t=a*b;

break;

case 3:cout<<"第"<<i<<"题"<<endl;

cout<<a<<"/"<<b<<"=";

t=a/b;

break;

if(b==0) goto loop;t=a/b;break;

}

do

{

cin>>num;

if(num==t)

{

cout<<"答案正确"<<endl;

}

else

{

cout<<"答案错误！正确答案是:"<<t<<endl;

}

}while(num!=t);

}

}

除法除不尽时会陷入死循环 ；答案错误不会继续出题，在思考解决方案
