C/C++ PROGRAM. Write a function that accepts two arguments, integer n and real number x, computes the following series, and returns the computed result:

1 2(x^2)/1! + 3(x^4)/2! 4(x^6)/3! + ... + [(-1)^n](n+1)(x^2n)!

Notation: 5!=5*4*3*2*1 means 5 factorial The general term is:

- negative one to the power of n

- multiply by (n plus one)

- multiply by x to the power of (2n)

- divided by n factorial

Then write a C program that request two input from the user:

-- an integer number, n -- a real number, x;

call the function passing those two input as arguments, output the result returned by the function.

You may assume that the user will always input n correctly, i.e., an integer 0 or above, and you are NOT required to test that n is a negative number. The following are some sample input combinations and results that you may use to check your answers: (For large n, n>=15, it is acceptable to have an answer different from the correct answer in the least significant digit)
