C++计算器代码

#include <iostream>
using namespace std;

int main()
{
  while(true)
  {
    try
    {
      int x;
      scanf("%d",&x);
      char c;
      scanf("%c",&c);
      int y;
      scanf("%d",&y);
      
      switch(c)
      {
      case '+':
        cout<<x+y<<endl;
        break;
      case '-':
        cout<<x-y<<endl;
        break;
      case '*':
        cout<<x*y<<endl;
        break;
      case '/':
        if(y==0) cout<<"除数不可以为0"<<endl;
        else
        cout<<x/y<<endl;
        break;
      default:
        break;
      } 
    }
    catch(exception e)
    {
      cout<<"出错！"<<endl;
    }
    
  }
  

  return 0;
}
