Take the tax program from the last homework assignment and implement it using classes and objects instead. To do so, create a class definition for a class called Customer with attributes income and tax. It should also have a set method for income, and a calcTax() method to assign tax and return it. As a reminder, the tax is calculated as follows: Income Tax Due $0 - $50,000 5% $50,000-$100,000 $2,500 + 10% of (income > $50,000) > $100,000 $7,500 + 15% of (income > $100,000) Create a Customer object in main, have the user enter the income and assign this to the income variable of the Customer object, and then call the calcTax() method for the Customer object and print the tax due.
Write a class that represents a player in a game. The player should have a name, password,experience points, an inventory array of four strings, and a location x,y. Your class shouldhave mutator and accessor methods for all variables. For example: setName(), getName(). Itshould have a suitable display method. Mutators and accessors should be public but allvariables should be private. To implement get inventory, use string * getInv(); Use the scoperesolution operator to implement larger methods such as display(). Use in class methods forshorter methods such as setName(), getName(). (in C++)Example:void setName(string name){this->name = name;}string *getInv();...string* player::getInv(){return inventory;}Note that in the above method setName “this->” is required for disambiguation. If writtenvoid setName(string n){name = n;}“this->” is not required.Write a test program that creates three players and displays them.Example Output:This program generates three player objects and…

Implement a class Season that represents a season during a specified year. For purposes of thisproblem, assume that the seasons in each year are, in order, 'Winter', 'Spring', 'Summer', 'Autumn' .__init__, __repr__A Season object is created by calling the constructor and supplying two optional arguments:1. season, defaults to 'Winter'2. calendar year, an int , defaults to 2023For the __repr__ , see the usage below: The next and prev methods modify a Season object by changing it to the next season or previousseason in sequence, respectively. Note that the seasons can "roll over" or "roll back" and that this maychange the year by +/-1. 1. During each year, the seasons occur in this sequence: 'Winter', 'Spring', 'Summer', 'Autumn' 2. next - change to next season, if the current season is Autumn then year will increase by 1 3. prev - change to previous season, if Winter then year will decrease by 1 Implement the == operator ( __eq__ method) to compare two Season…
