        Description:  Write code that will sum the place value digits of a number
                      provide by the user.

                      The user will be prompted to provide a number as well as the
                      number of digits this number contains. These two numbers
                      will then be passed into the place_value_add() function.

                      Inside this function the numbers will be used in a logical
                      statement that will strip each indivudal value and add them
                      together.  Once the final sum is determine(by digits) it
                      will be returned.

/* Sample output

This program will add the individual place values of a number that you provide
Please provide a number: 4352
Please provide the number of digits in your number: 4
The place value sum of your number is: 14
