   5 days ago · By default, the members of structs (and unions) are public, and the members of classes are private. However, we can explicitly set the access level of our members by using an access specifier. An access specifier sets the access level of all members that follow the specifier.

   Private functions ¶. In some cases, there are member functions that are used internally by a class, but that should not be invoked by client programs. For example, calculatePolar and calculateCartesian are used by the accessor functions, but there is probably no reason clients should call them directly (although it would not do any harm).

   Can a member function access private members?

   Usually member data are made private while functions (or methods) are made public. There might be instances where you might want to make certain functions private (i.e. you may not want the user to directly access these functions). Private functions can only be called from within public member functions.
