软件工程个人作业01

设计思想:

随机生成数,两个用来当做运算符两边的数字,一个用来判断运算符,循环30次输出

import java.lang.Math;
public class erzhuzi {
  public static void main(String[] args){
    for(int i=0;i<30;i++)
    {
      int firstone = (int) (Math.random()*100);
      int secondone = (int) (Math.random()*100);
      int yunsuanfu = (int) (1+Math.random()*4);
      if (yunsuanfu==1)System.out.println(firstone+"+"+secondone+"=");
      if (yunsuanfu==2)System.out.println(firstone+"-"+secondone+"=");
      if (yunsuanfu==3)System.out.println(firstone+"*"+secondone+"=");
      if (yunsuanfu==4&&secondone!=0)System.out.println(firstone+"/"+secondone+"=");
    }
  }

}

上课未完成原因:太笨了
