Exercise 3 (abstraction) Problem discerption Write a C# Program to calculate the area of a square using abstract class and abstract method. - Create abstract base class and derived class to calculate the area as the formula: square arca= side * side. - In the main() the program will ask the user to enter the length of the side of the square, define an object and call the suitable method.

Module/Week 7 ASSIGNMENT (ARRAYS)Use functional decomposition to write a C++ program that asks the user to enter his or her weight and the name of a planet. Use an enumerated type called planetType to represent the planets and use a switch statement that takes as its condition a planetType variable. The program, via the switch statement, then outputs how much the user would weigh on that planet. The following table gives the factor by which the weight must be multiplied for each planet. Your program must have the following functions in it: GetUserInput(), ConvertInputToPlanetType(), and OutputWeight() (your switch statement must be in OutputWeight()). I will let you determine what each function’s parameters and return types should be. The program will output an error message if the user does not type a correct planet name. The prompt and the error message will make it clear to the user how a planet name must be entered. Use proper formatting and appropriate comments in your code. The…
