include<bits/stdc++.h>

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

第一个代码应该是:

include<bits/stdc++.h>

using namespace std;

int main()

{ int a,b,ans; char c; cin>>a>>b>>c; if(c=='+') { ans=a+b; } else if(c=='-') { ans=a-b; } else if(c=='') { ans=ab; } else if(c=='/') { ans=a/b; if(a/b==0) { cout<<"Divided by zero!"<<endl; } } else { cout<<"Invalid operator!"<<endl; } cout<<ans<<endl; return 0; }

@python18

人狠话不多

上代码！

顺便求个关注

求求了！

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