Master Mind - computer game programming in C#

In summary, the program is a game where the user must guess the correct order and color of three hidden blocks. The computer will display how many colors are correct and how many are in the right position after each guess. There is currently no statement for determining the winner. The program could also use some optimization to eliminate unnecessary operations.

Homework Statement


Create this website:

In this game, there are four different coloured blocks (red, green, blue, and yellow). The computer hides three different coloured blocks from the user. The user then tries to guess the colours and the order of the blocks. After guessing the colour of the three hidden blocks, the computer displays:

  • how many of the colours are correct and
  • how many of the colours are in the right position.
Based on this information, the user can make another guess and so on until the user has determined the correct order and colour of the blocks.

The Attempt at a Solution

int intUserGuess2 = 0;// This variable will be used to store the second guess of the user inputted into the console

int intBlock3 = int.Parse(ret.Substring(2, 1));

Cannot find what is wrong with my program and I do not know where to fit in a statement that tells the winner if they have won. This program is in c#.

Does it work? If not, what exactly does not work?

I would do that at the place where you tell the user how many colors are in the correct position.A design question: if the correct colors are "1 2 3" and the user guesses "1 1 1", do you want to tell the user they have 3 correct color guesses? That's what you currently do. Sure, "1" does appear, but not as often as that reply could suggest As you do not allow repeated colors, you know that 3 of 4 colors are used, so that number is more of a "guess the missing color" anyway.

There are various pointless operations in the code (e.g. setting flag=true while you can be sure it is true, or setting intPlayGames to 0 if it is 2).

Okay thank you for the suggestions will try and work it out.
 

FAQ: Master Mind - computer game programming in C#

What is Master Mind?

Master Mind is a popular computer game that involves guessing a secret code within a limited number of attempts. It was originally created in 1970 by Mordecai Meirowitz and has since been adapted into various formats, including computer games.

What programming language is used to create Master Mind?

Master Mind is typically programmed using the C# programming language. C# is a general-purpose programming language commonly used for developing games and other applications.

How does the computer generate the secret code in Master Mind?

The computer uses a random number generator to create the secret code in Master Mind. This ensures that the code is different each time the game is played, adding to the challenge and replay value.

Can Master Mind be played on any computer?

Yes, Master Mind can be played on any computer that has a compatible operating system and has the necessary hardware and software requirements. It is often available on various platforms such as desktop, mobile, and online.

Are there any tips for programming Master Mind in C#?

One tip for programming Master Mind in C# is to use arrays to store and manipulate the code and the player's guesses. Additionally, using loops can make the code more efficient and easier to read. It is also important to thoroughly test the code to ensure it is functioning correctly.
