to me, compare is looking at 2 objects and see if they are equal or not. egalise a and b is a=b (change the value of a or b so that it is equal to the other value) is it clear :doh:
ok, i get what's your problem then... you are trying to speak english with french words ;P don't say equalize but assign. anyway, as you're using
std::strings, just use the = operator for this, and == operator to compare their content.std::string s1 = "Hello";
std::string s2 = "World";ASSERT(s1 != s2); // the objects contain different strings
s1 = s2; //Assign s2 content into s1
ASSERT(s1 == s2); // the objects contain same strings

OK, just to see if i have caught what you said: I should use == to compare if string s1 has the same content with string s2. That´s it? Because I already have tried that and it doesn´t work...:((

exactly. but be careful, the operator must be the overload of std::string class. in the expression
s1 == s2, if s1 is of type std::string, the code actually means to the compilers1.operator==(s2)(calling then the functionbool std::string::operator==(const std::string&)). but if s1 is a basic C-Style string (a char* basically), the compiler will try to compare the addresses, not the string contents... the context is exactly the same while using theoperator !=. so, can you please post a relevant (but small) piece of code which can reproduce the error ? also, specify to us the type of all the variables used, and which error you get (if it is a compiler error, linker error, or run-time error), and its message.

Hello, I would like to compare two strings: i used:
if (s1==s2) {I have no problem to compile, but even when s1=s2 it doesnt work... -
Oula je ne suis pas du tout enervé, choqué, ou autre. Je bois les paroles de tous ceux qui postent un message sur ce forum car je n´ai a mon actif ke 30h de langage c++. Je n´y connais pas grand chose. :) Je suis actuellement en stage et je dois realiser ce programme. Cela fait maintenant une semaine que je suis dessus, et je sens qu´il est tout près d´aboutir. Désolé si ma réponse a pu paraitre sèche, ce n´etait pas du tout l´esprit du message. C´est l´effet message ecrit qui ne transcrit pas le ton de la voix. :)
