生命游戏C++，检查邻居

我正在尝试编写康威的生命游戏。

不幸的是，当我去检查块的邻居时，我总是在数组中的某些元素上收到错误。具体来说，grid[0][11]它给了我一个邻居，但是，我设置了它，以便我只在它周围的块不是空格或代码中没有' '时向称为邻居的变量添加值。

我相信，if 语句中的条件也考虑到了它不会超出数组。

整个数组充满了' '，尽管如此，我仍然得到一个邻居的值。

我已经在这里呆了几个小时，但没有找到解决方案。我的代码仍然充斥着测试的尝试，我为它缺乏整洁性而道歉。提前感谢大家在解决我的问题时可以提供的任何帮助。

int _tmain(int argc, _TCHAR* argv[])
{
    bool infloop = true;
    //Create the playing grid.
    char grid[HEIGHT][WIDTH];
    //Comment out later. Used for testing.
    for(int i=0; i<75; i++)
        for(int j=0; j<22; j++)
            grid[i][j] = ' ';
    //Create initial seed here. grid [x coordinate] [y coordinate].
    //grid [1][1] = '+'; grid [2][1] = '+'; grid [3][1] = '+';
    //Key. * is going to live. + is alive currently. 
    //- is going to die, and negative space is dead.
    //As Conway's Game of Life runs infinitely, create an infinite loop.
    while (infloop)
