Implicit Typecasting & Explicit Typecasting

Md Ajmat

02/08/2017 2 0

In C++ it is possible to cast child class reference variable to parent class Reference.

When ever we are Converting a derived-class reference or pointer to a base-class reference or pointer is called implicit typecasting/upcasting. It is it quite natural also. A samaller data type can be casted to bigger one that won't make any data loss.

The downcasting/explicit typecasting, are the opposite of upcasting, is a process converting a base-class pointer or reference to a derived-class pointer or reference. It won't be done by the compiler implicitly.
