Operator overloading is a feature in C++ that allows operators to have user-defined meanings on user-defined types or classes. It is a type of polymorphism in which an operator is overloaded to give it a user-defined meaning. By overloading operators, we can give additional meaning to operators like +, -, *, /, =, etc., which by default are supposed to work only on standard data types like int, float, char, void, etc. .
In C++, we can specify more than one definition for a function name or an operator in the same scope, which is called function overloading and operator overloading, respectively. An overloaded operator is a function with a special name: the keyword "operator" followed by the symbol for the operator being defined. When an operator is overloaded, its original operational meaning might be expanded upon.
To overload an operator, we use a special operator function. We define the function inside the class or structure whose objects/variables we want the overloaded operator to work with. The syntax for overloading an operator is as follows:...
