In this case, we can't access Something::s_nValue directly from main(), because it is private. Normally we access private members through public member functions. While we could create a normal public member function to access s_nValue, we'd then need to instantiate an object of the cla...
A member function that is not declared as static is called a nonstatic member function. The definition of a member function is within the scope of its enclosing class. The body of a member function is analyzed after the class declaration so that members of that class can be used in the ...
