最近我发现了一些我很感兴趣的代码，但是我不能正确地理解它，所以有人能给我解释一下吗？
这是康威的生命游戏。我想这一行可以像一个问题，1表示真，0表示假;对吗？2但是为什么没有布尔值呢？

void iterGen(int WIDTH, int HEIGHT, char curMap[WIDTH][HEIGHT])
{
    int i, j;
    char tempMap[WIDTH][HEIGHT];

    for (i = 0; i < WIDTH; i++)
    {
        for (j = 0; j < HEIGHT; j++)
        {
            int neighbors = 0;
            neighbors += curMap[i+1][j+1] == '*' ? 1 : 0;
            neighbors += curMap[i+1][j] == '*' ? 1 : 0;
            neighbors += curMap[i+1][j-1] == '*' ? 1 : 0;
            neighbors += curMap[i][j+1] == '*' ? 1 : 0;
            neighbors += curMap[i][j-1] == '*' ? 1 : 0;
            neighbors += curMap[i-1][j+1] == '*' ? 1 : 0;
            neighbors += curMap[i-1][j] == '*' ? 1 : 0;
            neighbors += curMap[i-1][j-1] == '*' ? 1 : 0;

            if (curMap[i][j] == ' ')
            {
                tempMap[i][j] = neighbors == 3 ? '*' : ' ';
            }
            else if (curMap[i][j] == '*')
            {
                tempMap[i][j] = neighbors < 2 || neighbors > 3 ? ' ' : '*';
            }
        }
    }

    for (i = 0; i < WIDTH; i++)
    {
        for (j = 0; j < HEIGHT; j++)
        {
            curMap[i][j] = tempMap[i][j];
        }
    }
}
