Constructors are special methods that are automatically invoked when an object is created. They do not have a return type and cannot return values. Constructors initialize objects and can have default arguments but cannot be inherited or referred to by address.

1. CONSTRUCTORS
• They should be declared in the public section.
• They are invoked automatically when the object are
created.
• They do not have return type, not even void and
therefore, they cannot return values.
• They cannot be inherited, though a derived class
can call the base class constructor.
• Like other C++ functions, they can have default
argument.
• Constructors cannot be virtual.
• We cannot refer to their addresses
