// * Program Name: Assignment 3: Higher or Lower
// * Program Description: When the program is run, a random number ranging from 1 and 100 will be generated. The user inputs a number and the program will respond with either higher, lower or the same, depending on if the number inputted by the user is either higher, lower or the same as the number generated by the program. After each guess, the program will inform the user that the number they inputted is either higher or lower than the one the computer has chosen. The program will continue to run until the user guesses the correct number, in which the loop will exit and the program will inform the user that they have guessed correctly.
