程序要求：
设计程序帮助儿童练习减法，程序产生10个问题，每个问题为计算两个随机产生的一位整数，number1，number2，满足number1>number2，并给学生显示类似“what is 9-2”的提示，当用户输入答案后，程序输出一条信息，提示答案是否正确，问题全部回答后，程序报告回答正确的题数，提示使用rand()函数返回一个随机正整数，用srand()设置随机种子。。。
我的处女作
#include<iostream>
using namespace std;
int main()
{
  int number1,number2,answer,i,sum;
  i=0;
  sum=0;
  srand(124);
  while(i<10)
  {
  number1=rand();
  number2=rand();
  while(number1>number2)
  cout<<"what is number1-number2"<<endl;
  cin>>answer;
  if(answer=number1-number2)
   cout<<"your answer is right"<<endl;
   sum++;
   else
   cout<<"your answer is wrong"<<endl;
  
  i++;
  cout<<"the numbber of your right answer is "<<sum<<endl;
  }
  return 0;
}

#include<iostream>
#include <ctime>
using namespace std;

    int number1,number2,answer,i,sum;
    i=0;
    sum=0;
    srand((unsigned)time(NULL));
    while(i<10)
    {
        number1=rand()%100;

小问题太多了，要多注意点哦！

恩 谢了哈  我会向你看齐的  ！

看了你回的N个贴了，咋都是直接丢代码答案，先提出错误，让楼上的去思考一下啊，不然人会有依赖性的！
