Description
Write a C program that reads a double value (x) from the user and then uses it to compute the value of the mathematical constant e to the power of x (ex) and print it in main using the following infinite series:
ex = 1 + x/1! + x2/2! + x3/3! + x4/4! + …
Your program should include the following three functions:
- function called power which takes two parameters: x (double) and y (integer) and returns the value of xy . Function power MUST use a while loop. ( Not allowed to use the predefined function pow in math.h).
- function called factorial which takes one parameter x (integer) and returns its factorial. Function factorial MUST use a for loop.
- function called compute_ex which receives one parameter x (double) and returns the value of ex for the given x using the series above as well as functions power and factorial ( 1 and 2 above) . Function computer_ex MUST use a do/while The loop should stop when the new term added ( term = Xn/n! where n=0,1,2,3,…) to the series is less than 0.0001.
Example of a Sample Run :
Enter x
2.5
e to the power 2.50 = 12.18
VERY IMPORTANT:
- Turn in your assignment by replying to the course coordinator’s message on Ritaj and attaching your code file (c).
- DO NOT SEND a MESSAGE To YOUR INSTRUCTOR WITH YOUR ASSIGNMENT. DOING so will RESULT in RECEIVING a GRADE of ZERO for the assignment even if YOU TURN it in by the due date and time.
- You must include your full name, student id number, and lab section number in a comment at the beginning of your c code file.
