Repeatedly query the user for positive integer and determine the following for
each value:
a. Is the value a multiple of 7, 11, or 13? (Yes or No)
b. Is the sum of the digits of the integer even or odd?
c. Is the value a prime number? (Yes or No)
Main must prompt the user for the value and pass that value to a single function
which computes the answers to all three questions, returning the three results
to main as output (reference) parameters. Main then displays the results and
queries the user for another value, repeating the process until a sentinel value
is reached. Your solution MUST use a single function with three output
(reference) parameters; other solutions will not be accepted
