Question

Question 4

Problem 4. Construct a flowchart diagram, pseudocode and write a C++
program that displays the following menu:
<<<<< Geometry Calculator
>>>>>
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 _πr2
Use 3.14159 for TT 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.
