@xibaby 输入的顺序错了，是先输入a,c,再输入b

#include<bits/stdc++.h>
using namespace std;
int main(){
    int a,b;
    char x;
    cin>>a>>b>>x;
    if(x=='+') cout<<a+b;
    else if(x=='-') cout<<a-b;
    else if(x=='*') cout<<a*b;
    else if(x=='/'){
        if(b==0){
            cout<<"Divided by zero!";
        }else{
            cout<<a/b;

@hexuchen 因为我不想用 switch

@hexuchen 而且用 scanf 读 char 字符有时候会出问题
