Question

如果有其他人遇到此类问题。我为你留下了我的帖子。

我在抽象和继承方面遇到了一些麻烦。

我的代码假设以矩形，三角形和平行四边形的形式输出星号。

问题是三角形和平行四边形是以框形式出现的。

如果有人可以帮我找到问题并解释原因。

平行四边形

enter image description here public String toString（）

{
    String output = "";

for (int i = 0; i < mHeight; i++)

{
        for (int j = 0; j < mPbase+ i; j++)

{ 
          output += "* ";


}

        output += "\n";
        for (int l = 0; l <= i; l++) 
        {
            output += " ";
        }

    }
    output += "The area of this Pall is "  + calculatedArea() + " square 
units.";
    return output;

这是因为在循环宽度和高度时，您不计算该图层的宽度。如果我的宽度为5，高度为5，那么做一个标准的双循环将给我一个5x5。而是尝试从内部for循环的宽度中减去高度索引。对于三角形，这将至少打印出一个颠倒的三角形

WITH cte as
(Select distinct [Base Product] product from tblCrossSellData),
cte_table_a as
(
    SELECT DISTINCT OpOrID, OpPrSKU, OpQty, OpCancelled
    FROM tblOrder op  
    JOIN tblpayment orp  ON op.oporid = orp.PyOrID
    WHERE orp.PyDateNew BETWEEN @startdate AND @enddate AND opprsku = @sku       AND opcancelled = 0
),
cte_temp_b as
(
SELECT DISTINCT OpOrID, OpSoID, OpPrSKU, OpQty, ClID 
    FROM tblorder op
    INNER JOIN tblProduct m ON m.prsku = p.opprsku   
    INNER JOIN tblproclass c ON c.prsku = p.opprsku
    INNER JOIN tblpayment orp ON p.oporid = orp.PyOrID
    INNER JOIN cte ON p.opprsku = cte.product 
    WHERE orp.PyDateNew BETWEEN @startdate AND @enddate AND opsoid = @store
    AND OpCancelled = 0
),
cte_temp_c as
(
SELECT DISTINCT a.OpOrID, a.OpSoID
    FROM cte_table_a  a
    INNER JOIN cte_table_b b ON a.OpOrID = b.OpOrID
)
Insert Into #Output
SELECT @vsku as 'Base SKU', @sku as 'Related SKU', 
CAST(CAST(((CAST((SELECT COUNT(OpOrID) FROM cte_temp_c ) as float))
                    /CAST((SELECT COUNT(OpOrID) cte_temp_b ) as float)*100) as decimal(18,3)) as varchar(5)) + ' %'
     AS 'Cross-Sell Rate'

抽象与继承。输出错误
