A-LevelComputer ScienceObject-Oriented Programming (OOP)Oct/Nov 2022Paper 4 Q231 Marks
A computer program is being developed that uses a set of cards. The program is written using object-oriented programming. The program has two classes: Card and Hand. The methods and attributes of these classes are shown: Card Number: INTEGER stores the card number from 1 to 5 inclusive Colour : STRING stores the card colour: red, blue or yellow Constructor() takes a number and colour as parameters and sets the private values to these parameters GetNumber() returns the card number GetColour() returns the card colour Hand Cards : ARRAY[0:9] OF Card 1D array of type Card FirstCard : INTEGER stores the position of the first card in the hand NumberCards : INTEGER stores the number of cards in the hand Constructor() takes five card objects as parameters, assigns each card to the array Cards[], initialises FirstCard to 0 and NumberCards to 5 GetCard() takes an index as a parameter and returns the card at that index in the array
