Visible array size[40][20]: Code for Game Function Below: Question: How do I make a glider with five points dissapear of the edge of the array? I have expanded the array outside the visible array thinking this would work. But the glider seems to keep bouncing of the bounds in the printout.

row = r; colum = c;

sum += game[r][c]; //keeps track of if cells are all alive or dead

if (( r < 40) || (c < 20))

if (game[row][colum] == 1) livecount++; if (game[row - 1][colum - 1] == 1) livecount++; if (game[row - 1][colum] == 1) livecount++; if (game[row - 1][colum + 1] == 1) livecount++; if (game[row][colum - 1] == 1) livecount++; if (game[row][colum + 1] == 1) livecount++; if (game[row + 1][colum - 1] == 1) livecount++; if (game[row + 1][colum] == 1) livecount++; if (game[row + 1][colum + 1] == 1) livecount++;

if (livecount <= 2) game_t[r][c] = 0; if ((livecount == 3)||(livecount == 4)) game_t[r][c] = 1; if (livecount >= 5) game_t[r][c] = 0; }
