error C2872: 'string' : ambiguous symbol
1> could be 'e:///xxx///string'

Mam taki błąd podczas kompilacji, nie mam pojęcia co jest źle mógłby ktoś pomóc?

#include "stdafx.h"
#include <iostream>
using namespace std;

const int maxdl = 255;
class string
{
int dl;
char str[ maxdl ];

public:

void przydzielenie( char * st )
{
strcpy( str, st );
dl =( int ) strlen( st );
}
int dlugosc() { return( dl ); }

friend string operator +( string & a, string & b );
};

string operator +( string & a, string & b )
{
string temp;
temp.przydzielenie( strcpy( temp.str, a.str ) );
temp.przydzielenie( strcat( temp.str, b.str ) );
return temp;
}

int main()
{
string a;
string b;
string c;
cout << "podaj a" << endl;
cin >> a;
cout << "podaj b" << endl;
cin >> b;
c = a + b;
cout << c;

return 0;

}

wywal

using namespace std;

albo użyj innej nazwy dla swojej klasy.

Jeśli wyrzucam namespace, to mam same undeclared identifier.
Jeśli zostawie namespace i zmienie nazwę klasy to dostaje to:

No a Ty w ogóle rozumiesz co robisz...? Nie wczytasz do własnej klasy czegokolwiek za pomocą operatora cin::>> dopóki nie przeciążysz go odpowiednio.

Undefined się pokazuje, bo cout i cin są w przestrzeni nazw std::.
Drugi przypadek już opisałem wyżej.

Wykomentuj:

cout << "podaj a" << endl;
cin >> a;
cout << "podaj b" << endl;
cin >> b;
c = a + b;
cout << c;

i będzie działało, a potem zastanów się jak to poprawić.

Muszę przeciążać operator wprowadzenia?
Nie mogę stworzyć konstruktora, który dla każdego stringa tworzonego będzie traktował go jako tablice znaków , a metody klasy będą działały na referencjach?

Jeśli chcesz wczytywać przez std::cin, to tak.

Nie mogę stworzyć konstruktora, który dla każdego stringa tworzonego będzie traktował go jako tablice znaków , a metody klasy będą działały na referencjach?

?
Daj jakiś kod, bo nie wiadomo o co chodzi.
