LAB 5

1. Class definition #1

Write a program which defines a class for cataloguing videogames. The class should have three properties: the game name, the console name, and the year of production. All the properties are mandatory and must be provided.

Create 2 objects using the defined class. Provide the code below.

Now, make sure that all parameters are hidden and allow their retrieval with a getter method and their modification with a setter method.

Modify and display the properties of the two previously created objects. Provide the code below.

Create a method that provides the age of the video game by making a simple difference between the current year (2023) and the production year: game_age = curret_year production_year

In the previous code, use the method for calculating the game age for the two previously created objects.

Provide the code below.

2. Class definition #2

Write a program which defines a class for appliances. The class should have three properties: the device name, the power consumption, and the energy efficiency expressed as a percentage. The device name is a mandatory property, while the other two are optional and, therefore, can have a default value (e.g., 1 for 1 Watt and 50 for an efficiency of 50%).

Create 2 objects using the defined class. Provide the code below.

Create a method that provides the power losses as the product between the power consumption and the complement to 1 of the efficiency: power_losses = power_consuption * (100-efficiency)/100

In the previous code, use the method for calculating power losses for the two previously created objects.

Provide the code below.

3. Class modification

Consider the class created at the end of the first exercise. First, add a new parameter that indicates the number of plays of the user. Every time the user plays the video game, he will increase this property of one unit. Such a parameter must be optional, placed in the last position, hidden, and its default value is zero. Next, create a method to increase the number of plays and a getter method to display its current value.

Use the two previously created methods on the two objects.

Provide the code below.
