简单计算机器实现

解题思路:

注意事项:

参考代码:

#include<bits/stdc++.h>

using namespace std;

int main()

{

    int a,b;

    char c;

    cin>>a>>c>>b;

    switch(c)

    {

        case '+':

        cout<<a+b<<endl; break;

        case '-':

        cout<<a-b<<endl; break;

        case '/':

        cout<<a/b<<endl; break;

        case '%':

        cout<<a%b<<endl; break;

        case '*':

        cout<<a*b<<endl; break;

        default :

        cout<<"Error"<<endl; break;

    }

    return 0;
