This document describes a C# console application that is a random number guessing game. The program generates a random number between 1-50 and prompts the user to guess it. With each guess, the program tells the user if their guess is higher or lower than the random number. If the user guesses correctly, they are asked if they want to play again. The document provides code comments to explain the logic and flow of the program.

*********************************************************************//*
Description: This is a random number generated computer guessing program, where you try to match what the computer
has chosen as a stored random number. Each time you guess, the computer lets you know if your higher
or lower than the number stored. If you don't put a number or chose a number that is out of range the
computer will let you know and continue on (Note: This counts against your guessing). Each time you
press enter, whether or not you put a number, the game count continues higher as long as it is not
the number that the computer has stored. When you guess the number correctly, the computer lets you
know and you are prompt to enter Yes to start another game or No to exit the application. When you
exit the application, you will get a friendly prompt letting you know to press any key to exit.
