Design and implement a Visual C++ .NET program thatcomputes the approximate area that lies within a region bounded by a given curve y = p(x), the x-axis, and two specified vertical lines.

Click [here][1] for a picture of this region, and click [here][2] for an explanation how to approximate its area using rectangles.
We will assume that the curve is a simple polynomial y = p(x) = ax3 + bx2 + cx + d.
First prompt the user to enterthe values of these coefficients a, b, c, d.
Then prompt the user to enter the values of x at the leftmost and rightmost edges of the region.
Now that we know all the boundaries of the region, we next must determine the accuracy of the approximation. This accuracy is determined by the number of rectangles.
We will permit the user to compute the area using several different accuracies, to show how the accuracy improves as the number of rectangles increases.
Prompt the user to enter a minimum number of rectangles, a maximum number of rectangles, and an incremental number to add before each subsequent computation.
Finally compute and print the area using each specified number of rectangles.
The only libraries that may be included for this project are <iostream> and <cmath>.
Your program must define and call at least one programmer-defined function. This function must be appropriate and serve a useful purpose in your program.
Do NOT use any arrays.
## Deliverables
1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables):
