* A Constructor is a member function with the same name as that of its class and it is used to initialize the object of that class type with a legal initial value.

* Constructors are automatically invoked by the compiler.

* A Destructor is a member function with the same name as that if its class but is preceded by a tilde(~) and it is used deinitializes an object.

C++ can constructor be private

In C++, constructor is automatically called when object of a class is created. ... With the Named Constructor Idiom, you declare all the class's constructors in theprivate or protected sections, and then for accessing objects of class, you create public static functions.

Constructor Overloading. Constructor can beoverloaded in a similar way as function overloading.Overloaded constructors have the same name (name of the class) but different number of arguments. Depending upon the number and type of arguments passed, specific constructor is called.

In C++ programming, you can provide default values for function parameters. The idea behind default argument is simple. If a function is called by passing ...

*How does a class enforce data-hiding, abstraction, and encapsulation?

A class binds together data and its associated functions under one unit thereby enforcing encapsulation as encapsulation means wrapping up data and associated functions together into a single unit.

A class groups its members into three sections: private, protected and public. The private and protected members remain hidden from outside world. Thus through private and protected members, a class enforces data-hiding.

The outside world is given only the essential and necessary information through public members, rest of the things remains hidden, which is nothing but abstraction. As abstraction means representation of essential features without including the background details or explanation.
