Operator overloading in C++.
Types of polymorphism in C++.
This video lecture tells about operator overloading concept in C++ with practical implementation. The operator overloading is the static or compile time polymorphism type. There are several types of operators such as arithmetic or binary operator, logical operators, relational operator, and unary operator etc. The primary role of arithmetic operators is to perform some operation between operands but in polymorphism operators perform different role. In operator overloading, the operator is used as function name. The keyword “operator” is used to implement operator overloading in C++. All operators can be overloaded except some operators that are reserved. The operators such as (.,::,?:,.*) cannot be overloaded. When operator is overloaded then one operand must be user defined class object. In this video lecture, binary operator (+) overloaded as an example.
