game of life cpp代码

以下是Game of Life的C++代码示例：

#include <iostream>
#include <vector>
#include <chrono>
#include <thread>
#include <cstdlib>

using namespace std;

class GameOfLife {
private:
    vector<vector<int>> grid;
    int rows, columns;
public:
    GameOfLife(int r, int c) : rows(r), columns(c) {
        grid.resize(rows, vector<int>(columns, 0));
    }

    void initialize() {
        srand(time(NULL));
        for (int i = 0; i < rows; i++) {
            for (int j = 0; j < columns; j++) {
                grid[i][j] = rand() % 2;
            }
        }
    }

    int getNeighbourCount(int row, int col) {
        int count = 0;
        for (int i = -1; i <= 1; i++) {
            for (int j = -1; j <= 1; j++) {
                int r = row + i;
                int c = col + j;
                if (r >= 0 && r < rows && c >= 0 && c < columns && !(i == 0 && j == 0)) {
                    count += grid[r][c];
                }
            }
        }
        return count;
    }

    void nextGeneration() {
        vector<vector<int>> newGrid(rows, vector<int>(columns, 0));
        for (int i = 0; i < rows; i++) {
            for (int j = 0; j < columns; j++) {
                int neighbourCount = getNeighbourCount(i, j);
                if (grid[i][j] == 0 && neighbourCount == 3) {
                    newGrid[i][j] = 1;
                } else if (grid[i][j] == 1 && (neighbourCount == 2 || neighbourCount == 3)) {
                    newGrid[i][j] = 1;
                } else {
                    newGrid[i][j] = 0;
                }
            }
        }
        grid = newGrid;
    }

    void print() {
        for (int i = 0; i < rows; i++) {
            for (int j = 0; j < columns; j++) {
                if (grid[i][j] == 1) {
                    cout << "* ";
                } else {
                    cout << ". ";
                }
            }
            cout << endl;
        }
    }
};

int main() {
    int rows = 40, columns = 40;
    GameOfLife gol(rows, columns);
    gol.initialize();
    while (true) {
        gol.print();
        gol.nextGeneration();
        this_thread::sleep_for(chrono::milliseconds(100));
        system("clear");
    }
    return 0;
}

此代码实现了一个Game of Life模拟器，它使用随机值初始化单元格，并在每次迭代中计算每个单元格周围的邻居数量，然后使用规则进行更新。最后，它在控制台中打印游戏板并在每次迭代后清除屏幕。
