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
Unary operators operate on only one operand. The increment operator ++ and decrement operator --are examples of unary operators.
Binary operators work on two operands. For example, Here, + is a binary operator that works on the operands num and 9. When we overload the binary operator for user-defined types by using the code: The operator function is called using the obj1 object and obj2is passed as an argument to the function.
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.
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.
?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.
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.
