Adapted from Cambridge International AS & A Level Computer Science (9618), May/June 2024 Paper 41, Question 2.

Declare class Tree with private attributes:

TreeName
HeightGrowth
MaxHeight
MaxWidth
Evergreen

Write the constructor and getter methods. Then write procedure PrintTree(Item) that outputs a formatted summary. If Evergreen is "No", the final phrase must be loses its leaves each year; otherwise it must be does not lose its leaves.

The test harness reads one tree, creates the object, and calls PrintTree().

Input: Name, growth, maximum height, maximum width, evergreen value. Output: One formatted sentence.

Example:

Input:  Oak
        30
        20
        12
        No
Output: Oak has a maximum height 20 a maximum width 12 and grows 30 cm a year. It loses its leaves each year
