$4-$ Assume that you are asked to write a program for math students in order to demonstrate how to calculate volume and area of specific $3$D geometric shapes. Write a complete C$++$ program that offers a menu to the user and get relevant data according to the selected shape. Having done so$,$ the program would calculate either the volume or area of the selected shape and display this as the output. Hint: you can solve this question using if$/$else statement or with switch...case.

$\backslash$table$[[1-$ Calculate the volume of the cube,$V=a^3$
