7. The value e can be approximated by the sum 1+X + 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 e calculated using the predefined function exp. The function exp is a predefined function such that exp(x) returns an approximation to the value e. 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 variables 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
