Re: [Dev-C++] How would you write a method returning a string ?

[Jamiil A. <jal...@gm...>]

I have many classes that manipulate the string and then returns it either as 
a 'const char*', 'std::string', 'int', and so on and so forth, the method is 
just part of the class, so instead of writing a stand alone function, it is 
better to pack it up within the class, after all... that is the nature of 
Object Oriented Programming.
