What is override keyword in c sharp?

Answer 1

Operator Overloading is a Polymorphism concept. Standard unary and binary operators like (+, -, *, /, %, &, |, <<, >> ) have a predefined implementation that describes their behavior when applied on operands. However using operator overloading we can provide additional meanings to these operators.

For example we can add two integers using a + b. However the + operator cannot be used to add two objects for example two vectors. For this we need to overload the operator '+' so as to implement it toadd two vector objects.
