Question

i need to use fstream to read the file glidergunt.txt and make a glider gun game of life. the values for the glidergun.txt are

36
1 25
2 23
2 25
3 13
3 14
3 21
3 22
3 35

6 25
7 11
7 17
7 25
8 12
8 16
9 13
9 14

the code for the game of life is

#include <iostream>

}

}

}

}
void savePattern( int array1[ROWS][COLS], int ROWS, int COLS)
{

int total = 0;
for (int i = 0; i < ROWS; i++)
{
for (int j = 0; j < COLS; j++)
{
total += array1[i][j]; // count the number of live cells
}
}
outFile << total << endl; // output the count of point coordinates
for (int i = 0; i < ROWS; i++)
{
for (int j = 0; j < COLS; j++)
{
if (array1[i][j]) outFile << i << ' ' << j << endl; // output the coordinates in pairs
}
}
}
void liveOrDie(bool grid[ROWS][COLS])
{

bool grid2[ROWS][COLS] = {};
CopyGrid(grid, grid2);
for(int a = 1; a < ROWS-1; a++)

{

}
}
}

if(neighbors < 2) {grid[a][b] = DEAD;}
else if(neighbors == 3) {grid[a][b] = ALIVE;}
else if(neighbors > 3) {grid[a][b] = DEAD;}

}

}
}

int main()

{

int array [ROWS][COLS];
int n = sizeof(array) / sizeof(array[0]);
double fillPercentage;
fillPercentage = n;

bool grid[ROWS][COLS] = {};

grid[ROWS/2][COLS/2] = true;
grid[ROWS/2-1][COLS/2] = true;
grid[ROWS/2][COLS/2+1] = true;
grid[ROWS/2][COLS/2-1] = true;
grid[ROWS/2+1][COLS/2+1] = true;

for (int i = 1; i <= 50; ++i)

{

cout << " " << fillPercentage << " cycle #" << i << " Author: " << endl;
cout << endl;

Display(grid);
liveOrDie(grid);
Sleep(1000);

}
system("PAUSE");
return 0;

}
