For C++ language:

Please use a switch statement in this program.

Geometry Calculator 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): 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 = 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 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 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 circles radius, the rectangles length or width, or the triangles base or height.
