Write a program in C# Sharp to display the sum of the series [ 1+x+x^2/2!+x^3/3!+....]

Sample Output:

Calculate the sum of the series [ 1+x+x^2/2!+x^3/3!+....]:

Input the value of x :5                                                                                                         
Input number of terms : 5                                                                                                         
The sum  is : 65.375                                                                                                         
Number of terms = 5
