    This would be easier if more information was given. What kind of game? What library (opengl, allegro, so on..)? what for/purpose? etc...

    Example that might get you started (i made this in the reply window so it might be wrong).

    Code:
    int grid[3][3]; //3x3 grid
    int count = 1;
    
    for(int i = 0; i < 3; i++){
         for(int n = 0; n < 3; n++){
              if(i == 2 && n == 2) break; //stops from loading in 9th grid
              grid[i][n] = count; //assign 1-8
              count++;
         }
    }

    Hey there

    WHat i wanted to try to make is a game in 3*3 squares with 1 number in each square except the last one as i said in the other post. the blank one you are supposed to be able to move around and when you move the blank one where annother number is they switch places, and you win when you have the numbers lined up in order 1 to 8 etc.

    But what i had a problem with then starting this is getting a grid to load from file X why i want it to load from a file at start is becuase it going to make the numberd square be at random places at every start and keep track of what what numbers landed at wich places.

    i the way of looks i was thinking of someting like this

    Why would you have to load it from a file, unless you wanted to have pre-set grids for different difficulties. But loading from a file would not be random by nature. There is the rand() function (which sometimes doesn't appear too random from my experience). I would probably start by having the user being able to move in different directions, and set the values of the squares depending on the move.

    Pseudocode that should get you started
    Code:
    give user option to move in a direction
    if user tries to move outside grid don't allow it
    else set current square to the square you are moving to
    set moved to square to 0 or w/e you want
    edit: there are a lot of ways to approach the same problem
