Write a program in only C++ and explain it pleasssssseeeeeee.

A complex number can be expressed in rectangular (i.e. 7.67 + j2.56) or polar form (i.e. 8.086 e^j 0.322). In order to convert a complex number: a + jb to polar form: Ae^j theta, use the equations A = Squareroot a^2 + b^2, and theta = tan^-1 (b / a). In order to convert a complex number; Ae^j theta to rectangular form: a + jb, use the equations a = A cos(theta), and b = A sin(theta). Write a program that converts from one form to the other. It should (1) prompt for what sort of conversion to do: Convert to rectangular (1), or polar (2) form?: and then (2) ask for either A and theta (conversion to rectangular case), or a and b (conversion to polar ease). Your program should employ the proper conversion equations and then print out the results. You can word the statement something like: "7.67 + j2.56 is equal to 8.086exp (j0. 322)", for the conversion to polar case, and "8.086exp (j0.322) is equal to 7.67 + j2.56", for the conversion to rectangular case
