/*
 * read_divide_ints.c  --
 *
 *   Write a function that reads integer numbers character-by-character
 *   and that returns the corresponding int value (read until end-of-line
 *   and ignore all characters that are not digits). Use this function to
 *   read two int values, then print the quotient and remainder that result
 *   from dividing the first value by the second value. Also print the
 *   result of dividing the two numbers using the rules of floating-point
 *   division.
