Constructor.cs

/*
 * Constructor is a special method that is called when an object is created.
 * It is used to initialize the object, to assign values to the object's fields or properties.
 * The constructor has the same name as the class and does not have a return type.
 * They can be overloaded and a class can have multiple constructors.
 * There are two types of constructors:
 * Parameterized Constructor: Constructor with parameters.
 * Default Constructor: Constructor without parameters.
