**you ll notice that Euler's number is involved. The math library has a special built in function that uses Euler's number for the calculation. Please use that instead of defining a constant e value.

Question 4) For any integer n> 0, n! is defined as the product n * n – 1 * n – 2 .. * 2 * 1! is
defined to be 1. It is sometimes useful to have a closed-form definition instead; for this purpose,
an approximation can be used. R.W. Gosper proposed the following such approximation
formula:
n! z n"e-n
2n +
Create a program that prompts the user to enter an integer n, uses Gosper's formula to
approximate n!, and then displays the result. The message displaying the result should look
something like this:
Enter a value for
5! equals approximately 119.97003
5
For this problem, define a user defined function that performs the calculation. The user defined
function takes one argument of type int and will return the result of the computation of type
double to display. Name the user defined function FactorialApprox. Define a constant
macro called PI and set it to 3.14159265
