Bonuses

/* Write a program that applies bonus scores to given scores in the range [1..9].
 * The program reads a digit as an input. If the digit is between 1 and 3, the
 * program multiplies it by 10; if it is between 4 and 6, multiplies it by 100;
 * if it is between 7 and 9, multiplies it by 1000. If it is zero or if the value is not a digit,
 * the program must report an error.
 *   Use a switch statement and at the end print the calculated new value in the console.
