1804: 蓝桥杯算法提高- c++_ch02_02

解题思路:

注意事项:

参考代码:

#include<stdio.h>
#include<bits/stdc++.h>
using namespace std;
int main(){
    int a,b;
    char c;
    cin>>a>>b>>c;
    switch(c)// 用于判读符号 
	{
        case '+':
            // printf("%d%c%d=%d ",a,c,b,a+b);
            cout<<a+b<<endl;
            break;
        case '-':
            // printf("%d%c%d=%d ",a,c,b,a-b);
            cout<<a-b<<endl;
            break;
        case '*':
            // printf("%d%c%d=%d ",a,c,b,a*b);
            cout<<a*b<<endl;
            break;
        case '/':
            // printf("%d%c%d=%d ",a,c,b,a/b);
            cout<<a/b<<endl;
            break;
        case '%':
            // printf("%d%c%d=%d ",a,c,b,a%b);
            cout<<a%b<<endl;
            break;
        default:
            cout<<"输入错误"<<endl;
            break;
    }
    return 0;
