Here, a, b, and name are the private data members and count is a public data member. While, getA() is a private member function and getB() is public member functions.Example of Data members and Member functionsC++ program that will demonstrate, how to declare, define and access data ...
Two member function pointers are equal if they are both null or if their corresponding values of ptr and adj are equal. Note that the C++ standard does not require member pointers to the same virtual member function to compare equal; implementations using this ABI will do so, but only if t...
In general, the return type of a member function returning by reference should match the type of the data member being returned. In the above example, m_name is of type std::string, so getName() returns const std::string&. Returning a std::string_view would require a temporary std::...
