define a class named as rectangle with two data membera named base and height. input values for base and height in input function. define another function to calculate area of rectangle . define another class named as triangle to do the same. use friend function to compare the area of both shapes and display the name of a shape having more area.

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…

Please answer in C++ / Text book question / C++ for scientist and Engineers 3rd edition Construct a class named Fractions containing two integer data members named num and denom, used to store the numerator and denominator of a fraction having the form num/denom. Your class should include a default constructor that initializes num and denom to 1 and four operator functions for adding, subtracting, multiplying, and dividing the two fractions, as follows: Addition: a/b + c/d = (a * d + b * c) / (b * d)Subtraction: a/b - c/d = (a * d - b * c) / (b * d)Multiplication: a/b * c/d = (a* c) / (b * d)Division: (a/b) / (c/d) = (a * d) / (b * c) Finally, your class should have a member function that reduces each fraction to its terms (refer to Exercise 15 in Programming Projects for Chapter 6 for how to do this) as well as input and output functions for entering and displaying a fraction.   thanks
