Object Oriented Programming with C++, Second Edition

SUMMARY

• Constructor is a special method, used to initialize an object at the time of declaration. This Method has the same name as that of the class.
• The constructor enables an object to initialize itself when it is created. This is known as automatic initialization.
• When we define a class without any constructor, the system (compiler) supplies a constructor. It is called system supplied constructor.
• Do-nothing constructor is another term for system supplied constructor because such constructors do nothing!
• Constructors do not have return type declarations (even a void is not allowed).
• You cannot take addresses of constructors and destructors.
• Constructors in a class can be private (syntactically). However, it should always be declared as public. ...
