谁能给我一点提示？

#include <iostream>
#include <cmath>
using namespace std;
int main(){
    double a,b;
    char ch;
    cin>>a>>b>>ch;
    if(ch=='+'){
        cout<<a+b;
    }
    else if(ch=='-'){
        cout<<a-b;
    }
    else if(ch=='*'){
        cout<<a*b;
    }
    else if(ch=='/'&&b!=0){
        cout<<a/b;
    }
    else if(ch=='/'&&b==0){
        cout<<"Divided by zero!";
    }
    else{
        cout<<"Invalid operator!";
    }
    return 0;
}

@Zyuxuan 要用int
