Question
i need to generate a random pattern code for game of life code. also i need to calculate fill percentage. this is the code so far. image 1 is how it should look like but it obviously wont be the same as the initial pattern is completely random. then the code has to run for 50 cycles
#include <iostream>
#include <cstdlib>
#include <ctime>
#include <iomanip>
#include <windows.h>
#include <time.h>
#include <stdlib.h>
#define ALIVE true
#define DEAD false
using namespace std;
const int ROWS = 24;
const int COLS = 79;
void Display(bool grid[ROWS][COLS])
{
for(int a = 1; a < ROWS; a++){
for(int b = 1; b < COLS; b++){
if(grid[a][b] == true){
cout << "Q";
}
else{
cout << " ";
}
// if(b == COLS){
// std::cout << std::endl;
// }
}
cout << endl;
}
}
//This copy's the grid for comparision purposes.
void CopyGrid (bool grid[ROWS][COLS],bool grid2[ROWS][COLS]){
for(int a =0; a < ROWS; a++){
for(int b = 0; b < COLS; b++){grid2[a][b] = grid[a][b];}
}
}
//Calculates Life or Death
void liveOrDie(bool grid[ROWS][COLS])
{
bool grid2[ROWS][COLS] = {};
CopyGrid(grid, grid2);
for(int a = 1; a < ROWS-1; a++)

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