I agree with this prototype function. This is much safer.

First of all you don't need a standalone function to get a const char * from
a std::string. Try std::string.c_str() it returns a const char*. Second,
that is not what Object Oriented Programming is all about. Object Oriented
programming is about Inheritance, Data hiding, and polymorphism. Being able
to create a base class and inherit from that class to create other objects,
and to be able to hide the implementation and data, along with using
polymorphism.  Is what OOP is all about. If you have created a class that
isn't being use for inheritance, data hiding, and polymorphism, then all you
have done is created a class with a bunch of functions in them. If that is
the case, then that is not OOP.

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.
