A-LevelComputer ScienceObject-Oriented Programming (OOP)Oct/Nov 2024Paper 4 Q234 Marks
A computer program is designed to simulate horses doing show jumping. In show jumping, horses jump over obstacles called fences. A horse successfully jumps a fence if it does not knock the fence down. The program is written using Object-Oriented Programming (OOP). The class Horse stores data about the horses. Horse Name : STRING stores the name given to the horse MaxFenceHeight : INTEGER stores the maximum height in cm that the horse can jump, for example 132 PercentageSuccess : INTEGER stores the percentage chance of a horse not knocking down a fence, for example 70 represents a 70% chance of jumping a fence successfully Constructor() initialises Name, MaxFenceHeight and PercentageSuccess to its parameter values GetName() returns the name of the horse GetMaxFenceHeight() returns the maximum height the horse can jump Success() calculates and returns the percentage chance of a horse successfully jumping a specific fence
