輸入四個點(diǎn)，判斷此四點(diǎn)是否可形成一個平行四邊形。 程序中描述了一個抽象數(shù)據(jù)類型Vector2D，表示一個向量。具有（x,y）兩個值。其本身具有減另一個向量（minus(Vector2D)），判斷自身是否為零向量（iszero()），與另一個向量對應(yīng)值y,x乘積之差(inner(Vector2D))。由于兩個向量平行，則乘積之差x1*y2-x2*y1=0。點(diǎn)A，B，C，D四點(diǎn)組成平行四邊形的條件是AB//CD，BC//DA且各個向量皆不為零向量。 首先聲明四個向量。向量i獲得值的方法是由getPoint(int i)獲得。然后根據(jù)Vector2D重載后的toString（）函數(shù)將各個向量輸出查看。最后判斷此四點(diǎn)是否可組成平行四邊行。

If your application uses MFC in a shared DLL, and your application is in a language other than the operating system s current language, you will need to copy the corresponding localized resources MFC42XXX.DLL from the Microsoft Visual C++ CD-ROM onto the system or system32 directory, and rename it to be MFCLOC.DLL. ("XXX" stands for the language abbreviation. For example, MFC42DEU.DLL contains resources translated to German.) If you don t do this, some of the UI elements of your application will remain in the language of the operating system.

用fpga實(shí)現(xiàn)的DA轉(zhuǎn)換器，有說明和源碼，VDHL文件。 A PLD Based Delta-Sigma DAC Delta-Sigma modulation is the simple, yet powerful, technique responsible for the extraordinary performance and low cost of today s audio CD players. The simplest Delta-Sigma DAC consists of a Delta-Sigma modulator and a one bit DAC. Since, both of these components can be realized using digital circuits, it is possible to implement a low precision Delta-Sigma DAC using a PLD.
