const int ROWS = 22;
const int COLUMNS = 75;
class World
{
private:
char world_array[COLUMNS][ROWS];
bool out_of_bounds( int col, int row, bool verbose = false );
public:
World();
void display( bool side_marks = false );
void create_life( int col, int row );
void kill_life( int col, int row );
//add additional functions here:
void generation( char world_array[COLUMNS][ROWS] );
};

//2d world 75 by 22
cwin.coord(0,0,22,75);
char world_array[COLUMNS][ROWS];
World myWorld;
//initial cells
myWorld.create_life( init_cell_1_x, init_cell_1_y );
myWorld.create_life( init_cell_2_x, init_cell_2_y );
myWorld.create_life( init_cell_3_x, init_cell_3_y );
myWorld.create_life( init_cell_4_x, init_cell_4_y );
myWorld.create_life( init_cell_5_x, init_cell_5_y );
myWorld.create_life( init_cell_6_x, init_cell_6_y );
myWorld.create_life( init_cell_7_x, init_cell_7_y );
myWorld.create_life( init_cell_8_x, init_cell_8_y );
myWorld.create_life( init_cell_9_x, init_cell_9_y );
myWorld.create_life( init_cell_10_x, init_cell_10_y );
// display generation zero
myWorld.display();

what could be the issue of why its not displaying my life cells?
