CNick myNick("myUsername", "myRealname");
myNick.SetNick("newNickname");
std::string nickname = myNick.GetNick();This retrieves the nickname from the CNick object and stores it in the variable "nickname". The CNick class is not part of the standard C++ library, it is a part of the open-source library called "znc", which is a modular IRC bouncer written in C++. To use the CNick class in your own program, you would need to include the appropriate headers and link to the znc library.
