Sample Runs: (In the following sample run, the user input is shaded.)
Enter an integer greater than or equal to 0 and less than 100: 25

Your guess is higher than the number.
Guess again!
Enter an integer greater than or equal to 0 and less than 100: 5

Your guess is lower than the number.
Guess again!
Enter an integer greater than or equal to 0 and less than 100: 10

Your guess is higher than the number.
Guess again!
Enter an integer greater than or equal to 0 and less than 100: 8

Your guess is higher than the number.
Guess again!
Enter an integer greater than or equal to 0 and less than 100: 6

Your guess is lower than the number.
Guess again!
Enter an integer greater than or equal to 0 and less than 100: 7

You guessed the correct number.

The preceding program works as follows: The statement in Line 1 creates an integer
greaterthanorequalto 0 and less than 100 and stores this number in the variable num .
