What does operator overloading mean?

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.

Considering this, what is operator overloading 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.

Similarly, what does it mean to overload an operator in C++? Operator Overloading in C++This means C++ has the ability to provide the operators with a special meaning for a data type, this ability is known as operator overloading. For example, we can overload an operator ‘+’ in a class like String so that we can concatenate two strings by just using +.

Also Know, 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.

What is difference between function overloading and operator overloading?

Function overloading reduces the investment of different function names and used to perform similar functionality by more than one function. Operator overloading : A feature in C++ that enables the redefinition of operators. This feature operates on user defined objects.
