Step 1
Define what is meant by abstraction.
Answer
Abstraction is a concept in programming that focuses on hiding the complex implementation details of a system while exposing only the necessary and relevant parts to the user. It allows programmers to simplify their designs by creating a simplified model of the system, which leads to better code organization and easier maintenance.
Step 2
Give one example of how abstraction could be used when developing this program.
Answer
One example of abstraction in this program could be creating a class that represents a football match. This class could encapsulate attributes such as the teams involved, the score, and a list of goal scorers, while hiding the complexities of how the scores are calculated or how the information is stored.
Step 3
Complete the following pseudocode for an algorithm to count up how many matches with 0 goals are stored in the array and then print out this value.
Answer
01 nogoalscount = 0 02 for count = 0 to (goals.length-1) 03 if goals[count] = 0 then 04 nogoalscount = nogoalscount + 1 05 endif 06 next count 07 print(nogoalscount)
