Random number game. (help)

[prajeet10]

Hi, I have an assignment that requires me to write out the code for a game.
It involves 3 columns and random numbers between 0-100, so you have to place a random number into each column and as soon as the number below gets bigger, the game finishes. The main aim of the game is to go as many rounds as you can.
Could i get some help please. thanks.
Running program

  Round: 1 column 1:0     column 2:0       column 3:0
           In which column to put number 42?1

  Round: 2 column 1:42     column 2:0       column 3:0 
           In which column to put number 68?3

  Round: 3 column 1:42     column 2:0       column 3:68
           In which column to put number 35?2

  Round: 4 column 1:42     column 2:35      column 3:68
           In which column to put number 1?1

  Game Over. You'ver reached Round 4.

Show your code and then we may help you.

We dont have any code. Just the output of the program. Could u give the code??

[Labdabeta]

No, that is not what this website is for. You should try it for yourself and then ask for help with a specific problem.

[prajeet10]

Okay, so I have written down the code. I am stuck with declaring the rounds and columns and what loops to use. Could I get any recommendations for that?

[prajeet10]

// This is what we have so far. We need to limit the number of columns to "3" and each round number should change as the game progresses.
- Currently, when the program asks the user to input a column, it will accept any number and continue when there are only 3 columns.
- Also when "Round: 1" is over, it still says "Round: 1" on round 2.

Will you be able to help me out with this please?

• Currently, when the program asks the user to input a column, it will accept any number and continue when there are only 3 columns.

Put a validation after taking the user input.
If the validation fails,ask the user to enter again.

• Also when "Round: 1" is over, it still says "Round: 1" on round 2.

When you have hard coded "Round :1" in your code,

    cout << "\nRound: 1" << endl;

how do you expect it to change automatically with each iteration?

Have a variable to keep track of the rounds and use the same while printing this statement.

jst did hastily...make some alterations it will wrk.didnt have muj tym..i hope m given u sme idea to keep things smple also add some other functions along with the do while loop so it repeats with the round++ functn...kk

This is what I think would work as according to your question.
