Write a Python program that generates a random* integer between 1 and 100 (inclusive), and asks the user to guess what the number is. If the user's guess is higher than the random number, the program should display "Too high. Try again." If the user's guess is lower than the random number, the program should display "Too low. Try again." If, instead, the user guesses the number the program should congratulate the user. Use a function to generate the random integer to start the game.
