Write a program that asks the user for an input, x, of type double and an input, N, of type int. The program should then calculate the sum sigma^N_n = 0 x^n! Since you are calculating the factorial for each n, starting at 1, you do not need to calculate the factorial from scratch at each loop iteration. You can use the fact that n! = n*(n - 1)! As N gets large, your result should approach e^x. if x = 1, the sum should be ~2.71828. Remember if n! is larger than MAX_INT = 32,768, the value will be incorrect, so don't make N larger than 15. Also, 0! = 1 by definition
