- 1. Rainfall Class Write a RainFall class that stores the total rainfall for each of 12 months into an array of doubles. The program should have methods that return the following: • the total rainfall for the year • the average monthly rainfall • the month with the most rain • the month with the least rain Demonstrate the class in a complete program. Input Validation: Do not accept negative numbers for monthly rainfall figures.In a course, a teacher gives the following tests and assignments:• A lab activity that is observed by the teacher and assigned a numeric score.• A pass/fail exam that has 10 questions. The minimum passing score is 70.• An essay that is assigned a numeric score.• A final exam that has 50 questionsWrite a class named CourseGrades . The class should have a member named gradesthat is an array of GradedActivity pointers. The grades array should have four ele-ments, one for each of the assignments previously described. The class should have thefollowing member functions:setLab : This function should accept the address of a GradedActivityobject as its argument. This object should already hold the stu-dent’s score for the lab activity. Element 0 of the grades arrayshould reference this object.setPassFailExam : This function should accept the address of a PassFailExamobject as its argument. This object should already hold the stu-dent’s score for the pass/fail exam. Element 1 of the grades…Create a player class and a Key class. A Player hasa name, HP, and a key.

- # Coding - Simulate a robot Write a program that simulates the movements of a robot. The robot can have three possible movements: turn right turn left advance The robot is placed on a hypothetical infinite grid, facing a particular direction (north, east, south, or west) at a set of `{x,y}` coordinates,e.g., `{3,8}`, with coordinates increasing to the north and east. Create a Class `Robot` that contains a method `execute` which given a number of instructions will calculate the robot's new position, and the the direction in which it is pointing. ## Example The letter-string "RAALAL" means: Turn right Advance twice Turn left Advance once Turn left yet again Say a robot starts at `{7, 3}` facing north. Running this stream of instructions should leave it at `{9, 4}` facing west. ## Inputs and Outputs The argument of the `execute` is `string` in the format `X Y BEARING COMMANDS`. The method should return a one-liner `string` in the format `X Y BEARING`. In the…Create a class IntArray. Create two constructors.
