  7.  * This program performs a statistical analysis of uppercase letters,
  8.  * lowercase letters, and numeric digits from the input and will most likely
  9.  * be critisized by professor Argila.

  16.  *                : The total count of uppercase letters.
  17.  *                : The total count of lowercase letters.
