c++编写简单的计算器程序

首先来看下本人的开发环境

系统：win7
电脑：dell
运行环境：vs2015
语言：c++

简单计算器代码

//四则运算
#include "stdafx.h"
#include
#include
using namespace std;
void add()
{
  printf("输入要计算的加数（例如a b）n");
  int adda=0, addb=0,addc=0;
  cin >> adda;
  cin >> addb;
  addc = adda+addb;
  cout <> suba;
  cin >> subb;
  subc = suba-subb;
  cout <> mula;
  cin >> mulb;
  mulc = mula*mulb;
  cout <> dsa;
  cin >> dsb;
  dsc = dsa/dsb;
  dsd = dsa%dsb;
  cout <> operatione;
  cout << endl;
  try
  {
    if (operatione == 1)
    {
      //加法
      add();
    }
    else if (operatione == 2)
    {
      //减法
      substraction();
    }
    else if (operatione == 3)
    {
      //乘法
      multiplication();
    }
    else if (operatione == 4)
    {
      //出发
      division();
    }
    else if (operatione == 0)
    {
      exit(0);
    }
    else
    {
      throw 1;
    }
  }
  catch (int i)
  {
    cout << "输入错误" << endl;
  }
  operation();
}
 
int main()
{
  printf("欢迎使用本计算器");
  operation();
  return 0;
}

代码比较简单，希望大家能够喜欢
