How to check if a string is "0" ?

[Ardeshir81]

HI!
when i write :

string tmp ;
cin >> tmp;
if (tmp== "0") cout << "Zero" ;
//or instead of upper line :
if (!tmp.compare ("0")) cout << "Zero" ;

I see an error which says string couldn't be compared with int ;
But I thought if I put that in this : " "
It will count it as string .

Thanks in advanced

string tmp ;
cin >> tmp;
if (tmp== "0") cout << "Zero" ;

There is nothing wrong with this code.

Are you sure this is the actual code that is giving you the error?

Are you sure you're not doing this?

if(tmp == 0) // <- this would be wrong because 0 is not a string

if(tmp == "0") // <- this is fine
