Binary Operator Overloading
Binary Operators will work with two Operands. Examples of binary operators
include the Arithmetic Operators (+, -, *, /, %), Arithmetic Assignment operators
(+=, -+, *=, /+, %=) and Relational Operators etc. Overloading a binary operator
is similar to overloading a unary operator, except that a binary operator requires
an additional parameter.

Benefits of Operator Overloading :
1. Operator Overloading provides additional capabilities to
C# operators when they are applied to user-defined data
types.
2. Operators may be considered as functions internal to the
compiler.
