Grading Information: This Lab Homework is worth 76 points and due by Sunday of week 2 at midnight CST.

The purpose of this assignment is to assess if you can create a program that uses recursion.

DirectionsPoints
The file must be called week2Prog.cpp5
Program Definition
  1. Create program definition for sumDigits Function. Function will receive and return an integer.
6
Main Method
  1. Ask for input for numerous non-negative integers.
  2. Using pass-by-reference, pass integer received into recursive function called sumDigits.
  3. Receive result back from sumDigits and output result to screen.
  4. Include: system("PAUSE"); after your output to pause the screen.
    See example below.
20
sumDigits Function (Receives integer)
  1. Recursively call sumDigits adding up the integers received.
  2. Return result to main method for output.
  3. If a single digit is received, just return it to the main method.
30
Ensure you include ALL .cpp file(s) and any associated, student-defined .h (header) files required to make your program compile and run. The only files in the dropbox should be .cpp and .h files.  Do not turn in .zip, .exe, .rar, etc files.10
