C++ TUTORIAL FOR BEGINNERS: How to generate a random number, maximum random number & random numbers within a given range

/*
PROGRAM: How to generate a random number, maximum random number and random numbers within a given range

PURPOSE:
         The user is prompted to press any key to begin generating a random number. The program
         then returns to display a random number then the Maximum random number is displayed.
         The second part of the program is to let the user put a higher limit for the random
         numbers and a lower limit to generate random numbers within the required range of values.
         The program shows the values of those random numbers in the specified given range of limits.

dependent but it usually equal to 32767.
