Relational data is " flat " - that is , organized in the form of a two - dimensional array of rows and columns 關系數據是“平面的” ,即它是以具有行與列的二維數組的形式組織的。
For example , you can access the first element of the second row of the two - dimensional array by specifying indexes 例如,指定索引( 1 , 0 )可以訪問二維數組第二行的第一個元素。
Up until now , we haven t dealt with two - dimensional arrays ; however , as you can see below , the syntax is quite simple 目前,我們還沒有處理過二維數組;但是,在下面可以看到,語法非常簡單。
Create matrix array builds a two - dimensional array that contains two columns and three rows , and then displays it in a list box 創(chuàng)建矩陣數組生成一個包含兩列和三行的二維數組,然后在列表框中顯示。
The following code shows a call in which a two - dimensional array is passed to a procedure that expects a one - dimensional array 下面的代碼演示一個調用,其中,二維數組被傳遞到需要一維數組的過程中。
You might declare a two - dimensional array with 12 rows for the months and 31 columns for the days , as the following example shows 可以聲明一個具有12行(表示月)和31列(表示日)的二維數組,如下例所示。
The following is a declaration and initialization of a single - dimensional jagged array that contains two - dimensional array elements of different sizes 下面聲明和初始化一個一維交錯數組,該數組包含大小不同的二維數組元素:
Of office counts , for buildings 0 through 40 and floors 0 through 5 . dim officecounts 40 , 5 as byte a two - dimensional array is also called a 下面的示例聲明一個變量來保存一個“二維數組” ,組元素是辦公室的數量,建筑物從0到40 ,樓層從0到5 。
Floating tool palette , which behaves like a toolbar but displays a two - dimensional array of tool buttons and floats as a modeless window above the owner frame window 浮動工具調色板,其行為類似于工具欄,但顯示一個二維工具按鈕數組并以無模式窗口的形式在所有者框架窗口上浮動。
Researched the methods to test configrable logic block ( clb ) and its sub - blocks . based on a “ divide and conquer ” methodology , the clb resources are divided into three basic blocks : logic units , carry logic module ( clm ) and lut ’ s ( look up tables ) ram - mode . the testing configurations are implemented based on a two - dimensional array structure for logic blocks 主要基于“分治法”對clb及其子模塊進位邏輯( clm ) 、查找表( lut )的ram工作模式等進行了測試劃分,分別實現了以“一維陣列”為基礎的測試配置和測試向量,以較少了測試編程次數完成了所有clb資源的測試。
