hello evrybodyyyyyyyyyyyyyy

i hope someone can help me with this , i have no idea how to start , this kind of problem is new for me help me pls pls pls pls



1. The value ex can be approximated by the sum
1 + x + x2/2! + x3/3! + … + xn/n!
Write a program that takes a value x as input and outputs this sum for n taken
to be each of the values 1 to 100. The program should also output ex
calculated using the predefined function exp. The function exp is a predefined
function such that exp(x) returns an approximation to the value ex. The
function exp is in the library with the header file cmath. Your program should
repeat the calculation for new values of x until the user says she or he is
through.
Use variable of type double to store the factorials or you are likely to produce
integer overflow (or arrange your calculation to avoid any direct calculation of
factorials). 100 lines of output might not fit comfortably on your screen. Output
the 100 output values in a format that will fit all 100 values on the screen. For
example, you might output 10 lines with 10 values on each line.

Well, I'm not going to write the thing for you, but I can give you a few tips:

1. Write a function to determine the factorial in each case:

int factorial(int n)
{
     if(n != 0)
       return n*factorial(n-1);
    else return 1;
 
}
 

2. Write a function to define the given function.

3. Write a function to put the two together

I'm not here to do your homework for you so go on, the factorial function is a recursive function which should help you alot
