C++ C+的Averageif函数等价物+；

我是一名编码初学者，我正试图缩小一大块容易出错的代码。我非常想要它

if (tileBlocked[row - 1][col] == true)
{ 
    add tileAir[row - 1][col] to averaging
}

这样，仅当TileBlock未将该区域列为阻塞区域时，我才能找到数组tileAir中值的平均值。我四处搜索，唯一找到的是Averageif，据我所知，它只适用于excel。是否有任何等效的或某种方式可以减少这段代码的大小并允许更好的扩展能力

现在这是我当前的代码：

for (int row = 1; row < 255; ++row) // Repeats for all rows, skipping the first and final row
    {

        for (int col = 1; col < 255; ++col) // Repeats for all columns, skipping the first and final column
        {

            bool check[4] = { tilesBlocked[row - 1][col], tilesBlocked[row][col - 1], tilesBlocked[row][col + 1], tilesBlocked[row + 1][col] }; // Creates an Array for testing what tiles should be ommited from the calculation

            if (tilesBlocked[row][col][0] == true) // If the tile being calculated is blocked, skip it
            {
            }
            else if (check[0] == true && check[1] == true && check[2] == true && check[3] == true)
            {
            }
            else if (check[0] == false && check[1] == false && check[2] == false && check[3] == false)
            {
