编译失败

#include<iostream>
using namespace std;

    int a,b;
    char c;

            return 0;

else没加分号

cout<<"Invalid operator!" 这句话没加分号

by Cary1075 @ 2023-07-20 15:12:10

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

改完之后为什么还是不行？

    return 0;
}

if语句不加大括号只能括一个语句，你看看你的那个if，里面有一个return 0，所以这个地方报错了，改一下去

by Cary1075 @ 2023-07-20 15:20:53

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

这样好像可以了

谢谢

@Cary1075 你家伙直接copy别人的代码是吧

输出语句没加分号
