 OOP 313304 Practical No.19: Write programs to overload the unary operator using- The member function and Friend function

The concept of operator overloading helps to assign a new meaning to the existing operator and helps to extend the concept of polymorphism.

OOP 313304 Practical No.19 Exercise:

1. What is function overloading and operator overloading?

Answer:

2. State output of the following code:

Answer:

Output:

F: -11 I: -10 

F: 5 I: -11

After applying the unary minus operator, the signs of the feet and inches are inverted for both D1 and D2.

Therefore, D1 changes from (11, 10) to (-11, -10), and D2 changes from (-5, 11) to (5, -11).

3. Overload the unary operator –(minus) using member function and friend function

Answer:

Result

The result of the above C++ codes is that the Distance objects' feet and inches values are negated when the unary minus operator is applied, resulting in F: -11 I: -10 and F: 5 I: -11 being displayed.
