Write a 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): Use a do/while loop and a switch statements to implement this program. 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 = r² 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 rectangles area. Use the following formula: area = length * width If the user enters 3 the program should ask for the length of the triangles base and its height, and then display its area. Use the following formula: area = base * height * .5 If the user enters 4, the do/while loop should terminate, and 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. The do/while loop should continue invalid input. Do not accept negative values for the circles radius, the rectangles length or width, or the triangles base or height.
