Chapter 5 Programming Exercise Random Number Guessing Game

Create an application that generates a random number in the range of 1 through 100 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 the user guesses the number, the application should congratulate the user.

The game should keep count of the number of guesses and display the results of the guess in a list box, as shown in the example below. The “get random number” button should reset the number & set the count back to 0.

You need to “hold on” to the value for the number of guesses and the random number for longer than one button click, so be careful of that. You need to count how many guesses it takes the user to be successful. Please place a “cheat box” by displaying the random number. This helps you when you’re testing your program, to be sure your code is working properly.

Needs to be done in Visual Studio 2017.

Need the code for the program.

Form must have Guess Button, Exit Button, Get Random Number Button, an area for the user to enter the number they are guessing, and a "CheatBox" area that gets the number they entered and displays it for the programmer to ensure the program is functioning property, as well as a ListBox and a few other items.

Explanation / Answer

Visual Studio is an integrated development environment its is not a programming language. As you have not mentioned in which programming language do in need to write the code i am considering Java Programming language
