What is operator overloading in object oriented programming?
Besides, what is operator overloading in OOP with example?
Operator overloading allows you to redefine the way operator works for user-defined types only (objects, structures). It cannot be used for built-in types (int, float, char etc.). Two operators = and & are already overloaded by default in C++. For example: To copy objects of same class, you can directly use = operator.
Also, what are the rules for operator overloading? The first and basic rule of operator overloading is: we can overload unary operator as only unary operator, it cannot be overload as binary operator and vice versa. We cannot overload those operators that are not a part of C++ language like ‘$’. We can perform operator overloading in only user defined classes.
People also ask, what is meant by operator overloading?
Operator overloading is an important concept in C++. It is a type of polymorphism in which an operator is overloaded to give user defined meaning to it. For example ‘+’ operator can be overloaded to perform addition on various data types, like for Integer, String(concatenation) etc.
Why do we use operator overloading?
C++ Operators OverloadingIt is used to perform the operation on the user-defined data type. For example, C++ provides the ability to add the variables of the user-defined data type that is applied to the built-in data types. The advantage of Operators overloading is to perform different operations on the same operand.
