1. Calculate the Area of a Circle
2. Calculate the Area of a Rectangle
3. Calculate the Area of a Triangle
4. Quit
Enter your choice (1-4):
If the user enters 1, the program should ask for the radius of the circle and then display its area. Use the following formula:
area = Pi*r^2
Use 3.14159 for and the radius of the circle for r. If the user enters 2, the program
should ask for the length and width of the rectangle and then display the rectangle’s area. Use the following formula:
area = length * width
If the user enters 3 the program should ask for the length of the triangle’s base and its height, and then display its area. Use the following formula:
area = base * height * .5
If the user enters 4, the program should end.
Input Validation: Display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu. Do not accept negative values for the circle’s radius, the rectangle’s length or width, or the triangle’s base or height.

- An online music and apps store offers all apps for 3$ each and all songs for 7$ each. The store requires members to prepay any amount of money they wish, and then download as many apps or as many songs accordingly. You are required to write a program that would ask the user for the amount that he/she will pay, then display two messages indicating: -the maximum number of apps that can be downloaded, and how much funds will remain in the account after that, if any. -the maximum number of songs that can be downloaded, the number of apps that can be downloaded after that if funds allow, and how much funds will remain in the account after that, if any. Notice the parenthesis in app(s) and song(s) in the output. For this assignment, assume that the user will always enter a valid integer value that is >= 0, and within the limit of the integer range.

The algorithm should be able to accept the upper- and lower-case versions of all character input options and should be able to deal with invalid options being input for all input (including the number required for part c). Note: for the first two options, the program does not need to read in your name/tutorial time and then print this out. It simply needs to output a message that you hard code into the program.

- Objectives: • Provide a game solution using C++ language. It is important that we can use a set of C++ features to solve problem. • Develop solutions that use class features for C++. • Create "*.h" files and "*.cpp" files for classes. Description: 1. Part 1- Required Assignment: a. Write code for the class GamePurse. It has the following interface Iclass GamePurse { int purseAmount; public: GamePurse(int); void win(int); void Loose(int); int GetAmount(); }; b. Win() function will add a winning amount to the purseAmount. On the other hand, Loose function will deduct an amount from the purseAmount. GetAmount() will return the value of "purseAmount". c. Write a program that allows you to play the dice game repeatedly until the user chooses to quit. User needs to bet a positive amount to play a game. d. The output of the program may be like the following Welcome to the dice ware game. You have 100 in your game purse.arrow_forwardoe’s Pizza Palace needs a program to calculate the number of slices a pizza of any size can be divided into. The program should perform the following steps: Ask the user for the diameter of the pizza in inches. Calculate the number of slices that may be taken from a pizza of that size. Display a message telling the number of slices. To calculate the number of slices that may be taken from the pizza, you must know the following facts: Each slice should have an area of 14.125 inches To calculate the number of slices, simply divide the area of the pizza by 14.125. The area of the pizza is calculated with this formula: Area NOTE: π is 3.14159. The variable r is the radius of the pizza. Divide the diameter by 2 to get the radius.arrow_forwardA car’s miles-per-gallon (MPG) can be calculated with the following formula:MPG 5 Miles driven Gallons of gas usedWrite a program that asks the user for the number of miles driven and the gallons of gas used.
