Please, Do not modify Main function. Void guess_num needs to be implemented only.

Implement function guess_num that generates a random integer number between 0 and 100 and lets the user guess the number. The function performs three major steps. First, it generates a random integer number num using the rand function. Second, it prompts the message Enter your guess: and takes a number from the user as input. Third, it checks whether the number entered by the user is identical to num. If so, it displays the message Congrats! Your guess is correct and exits. If the entered number is larger than num, it displays the message Your guess is too large. Try again. and goes back to step 2. If the entered number is smaller than num, it displays the message Your guess is too small. Try again. and goes back to step 2.

You can use the command man rand to find more information on how to use the rand function. A sample execution of the function is as below:

Enter your guess: 27 Your guess is too small. Try again. Enter your guess: 45 Your guess is too large. Try again. Enter your guess: 32 Congrats! Your guess is correct.
