/**
 * This program computes the sum of any number of integers given by the user.
 * It repeatedly prompts the user for the next number until the user enters 'q'.
 * The program then reports the sum of the numbers.
 *
 * Bugs: The program assumes that each time the user is prompted, the user
 *       enters either an integer or 'q' (or 'Q').  That is, no error-checking
 *       of the user's input is done.
