memory game
 

Hi all i am working on a memory game and i am having problems inputing the data so it checks if a 3rd number is pulled up to ignore it
thanks in advance

int card[6][6],total=0,value,test; 

        srand((unsigned)time(NULL));//randomize timer



        for (int i=0;i<6;i++)

        {

                for (int j=0;j<6;j++)

                {

                        value=rand()%18;//random

                        test=0;

                        card[i][j]=value;//sets the value

                        for (int x=0;x<6;x++)

                        {

                                for (int y=0;y<6;y++)//starts the check for doubles

                                {

                                        if(value==card[x][y])

                                        {

                                                test++;

                                                cout<<i<<endl;

                                        }

                                        if (test==3)

                                        {

                                                //need a code to stop for the 3rd one to be put in.

                                        }

                                }

                        }

                }

        }

Re: memory game
 

It might help to describe how the game works and how your program logic accomplishes that. Saying that you need some code for the program to ignore a 3rd number that's pulled up means nothing to us.

well it is a memory game where you match 2 numbers
and i want random numbers between 0 and 17 on the board i need 2 of the same number on the board

Re: memory game
 

So you want to populate the board with random numbers in the range of [0, 18) and disallow more than two of a kind? I'd say use a frequency table for the range since it's small, and repeat getting the random number until you find one that doesn't go beyond the limit:

#include <cstdlib>

#include <iomanip>

#include <iostream>



int main()

{

  using namespace std;



  int board[6][6];

  int freq[18] = {0};



  for ( int i = 0; i < 6; i++ ) {

    for ( int j = 0; j < 6; j++ ) {

      int r;



      do

        r = rand() % 18;

      while ( freq[r] >= 2 );



      ++freq[r];

      board[i][j] = r;

    }

  }



  for ( int i = 0; i < 6; i++ ) {

    for ( int j = 0; j < 6; j++ )

      cout<< left << setw ( 3 ) << board[i][j];

    cout<<'\n';

  }

}

The frequency table holds a count of all of the values in your range.

oh wow that is a different way thinking about it. thanks
