    Game Of Life

    hi all
    Im a new person here and probably quite new in c programming.
    I just want to ask some help.
    Everyone here have heard about this game before??
    Does anyone have try to code this program??
    Can I see the code??

    All code can be sent to din0908@gmail.com
    This is my first project and I'm still cannot understand the implementation of an array 2d.....
    Hope you guys all can help a little bit..

    Thx all.

    If this is homework, try to do it yourself first. If this isn't homework, try to do it yourself first. If you get stuck, post your code.

    Also, try google. Here's a wonderful link, too:

    http://en.wikipedia.org/wiki/Conway%27s_Game_of_Life

    A 2D array is like a 1D array, except it has two dimensions. :P

    Code:
    int array[30][30];
    You can access each element using array[x][y]. So define an array, initialise it to a state representing "dead" cells, then put a few "live" cells in. Then iterate through the array and apply the Game of Life rules to it. You may need to keep two copies of the array, because the next iteration of game of life needs each cell to know about the previous state, and your calculations will clobber the old state.

    Yes

    No

    Yeah right!
    Do your own fsking homework next time.
    Anyone too dumb to type in "game of life source code" into google deserves to fail miserably.

    Hahaha.....I actually have wrote a quite long code for the interface. And now I have to make the array board. it quite suceesful actually but the problem is everytime I run the part of the array, there is some unneccesary symbol appear in my array...

    I actually ask for the code only for the reference..the is no way im going to use it to be sent to my lecture.... learning C from example is more understandable than read the whole book about the sintaks....

    So post it, and then perhaps we can tell you where you're going wrong.

    > I actually ask for the code only for the reference
    Looking at other peoples code no more teaches you C than reading a book does. Chances are, the C code is a worse example than a decent book.

    Find examples of source code using Google and try to understand them. After that, translate one into C and see what you get.

    This Google search produced some good results:

    Code:
    "game of life" source
    as evidenced here

    Din1983, edit your post to remove your e-mail address. As Salem has pointed out (in his usual manner) nobody is going to e-mail stuff to you: firstly it defeats the object of having a forum and secondly it's not the way this board operates. The only thing you will get is spam once a spambot harvests your address. This will only be a matter of time.

    Salem, you should also edit your post to remove his e-mail address for the same reason.

    The weird symbol ..... I already get rip off it.... and now im implement the code for program generate the next generation.... I think this is the most critical part of it...

    Question: can I use this kind of code in C array ??
    Code:
    for(x=1;x<9;x++){
        for(y=1;y<9;y++){
              if (cell [x] [y+1] == '*')
                   counter ++;
              if(cell [x] [y-1] == '*')
                    counter ++;
               ...........and so on......
             }
       }

    Is that code mean ..... the counter is added when the condition is true right??
    Anyone have a good code to show??

    Post your actual code.

    Code snippets containing a few statements and then "...........and so on......" just don't cut it, and won't get other people to finish the code for you.

    Alright...sory for that...

    Code:
    int counter()
    {
    for (x=1;x<9;x++){
          for (y=1;y<9;y++){
          if (cell [x+1][y+1] =='*')
                   counter++;
          if (cell[x+1][y] =='*')
                   counter++;
          if (cell[x+1][y-1] =='*')
                   counter++;
          if (cell[x][y-1] =='*')
                   counter++;
          if (cell[x-1][y-1] =='*')
                   counter++;
          if (cell[x-1][y] =='*')
                   counter++;
          if (cell[x-1][y+1] =='*')
                   counter++;
          if (cell[x][y+1] =='*')
                   counter++;
          
               }
         }
         return counter;
    }
    Any mistake in this code??

    > counter++;
    Well did you compile it?
    For a start, this is also the name of your function, so the chance that it will compile is zero.

    > cell [x+1][y+1]
    How did you define the cell array - you need at least 10x10
    You also need to make sure the strip of cells around the perimeter are initialised to say zero.

    This is my full code for the program so far.... it is not quite complete actually... and I do hope someone can understand it and try to find the error for me....

    This game consist of 2 gameplay call Machine destiny Game and Human destiny Game.... In machine game the pattern of the cell is generate randomly but in the human game the user can define their own pattern...

    The problem might be with the array and also function call...I think I might need to study more on it....here is the long code...the longest code I ever wrote...hehehe....

    Code:
    /*Projek:Game Of Life*/
    
    #include <stdio.h>

    void papar_buat_corak();//function for user enter the location of cell

    Question: in this game, the pattern of cell are created in one function. in other function, I want to count the neighbour of the cell based on the cell pattern that already create before. so what is the sintaks for my function to count the cell neighbour??I still cannot understand how the function is going to retrieve the cell pattern created and use it in that function.....

    it is like this....
    Code:
    void create_pattern ( char cell[x][y] );
    int count_neighbour ( char cell[x][y] );
