/* This is a simple example to test input validation. The user must create an account with an username and password. The username must be the student number.
 * This will determine if the username is of exactly 9 digits. It will also determine if the user enters a password
 * with the following characteristics.
 *      1. 8 or more characters of length
 *      2. At least 1 upper case letter
 *      3. At least 1 lower case letter
 *      4. Al least 1 symbol
 *      5. At least 1 digit
 * The program will not finish until the user enters a correct password and then re-enters the same password.
