You could write a very short, trivial  wrapper to map strcmp's output to an 
enumeration, so that it better suits your needs. However, with the string 
class in standard C++, you don't need that stuff anyway in most cases. You 
can just write it straightforward, thanks to overloaded operators:

#include <iostream>
#include <string>

using namespace std;

int main( void ) {
        string a( "Hello, world!" );

        if( a == "Hello, world!" )
                cout << "pass." << endl;

        exit(0);
}
