How to overload a binary operator?
Operator Overloading can be done by using three approaches, i.e. Overloading unary operator. Overloading binary operator. Overloading binary operator using a friend function. In the case of a non-static member function, the binary operator should have only one argument and the unary should not have an argument.
What is overloading (-) unary operator?
Let us consider overloading (-) unary operator. In the unary operator function, no arguments should be passed. It works only with one class object. It is the overloading of an operator operating on a single operand.
What is the difference between binary operators and unary operators?
?Unary operators have a single argument and binary operators have two arguments. ?When an operator is used, the operands become the actual arguments of the "function call". ?Therefore, the formal arguments must match the data type(s) expected as operands or a conversion to those types must exist.
How many arguments should a binary operator have?
In the case of a friend function, the binary operator should have only two arguments and the unary should have only one argument. All the class member objects should be public if operator overloading is implemented.
