@Heidip Divided by zero 和 Invalid operator 后面要加感叹号

@Heidip

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