10.3 Class Constructors and Destuctors To accomplish initialization while declaration for class objects, C++ provides special member functions calledclass constructors. In fact,a constructor has no return type, its name is often same to the class's name. For example: constructor for class Stock i...
The most striking part of class isthe binding of data and methods into a single unit access control There are two access control keywords for class members up till now: public: any program that uses the object of the class can access the public part directly private: a program could access...
The wrapping up of data and function into a single unit (called class) is known as encapsulation. The data is not accessible to the outside world and only those functions which are wrapped in the class can access it.These functions provide the interface between the objects data and the pro...

Each document creates a new CDB object in its OnNewDocument function and stores a pointer to the object in CDB::m_pDB. The document class implements four menu items: Create Write Read Read multiple Create adds a new table called "Testing" to the database associated with the document and ...
the MyClass object will be forwarded to my_function exactly the same as if the IC function wasn't there. The my_function will continue receiving a rvalue reference to a MyClass object.This approach however is not so practical when the function has multiple arguments. On the code:my_...
Class string and String Stream Processing result in syntax errors. Assigning a single character to a string object is permitted in an assignment statement as in Unlike C-style char * strings, strings are not necessarily null terminated. [Note: The C++ standard document provides only a description...
