詞法分析 1 試驗目的 設計,編制并調試一個此法分析程序,加深對此法分原理的理解. 2 試驗要求 1)待分析的簡單語言的詞法 * 關鍵字: begin if then while do end 所有關鍵字都是小寫. 2)運算符和界符: : = + * - / < <= <> > >= = ( ) # 3)其他單詞是標識符(ID)和整數型常數(NUM),通過一下正規式定義: ID=letter (letter|digit)* NUM=digit digit* 4)空格由空白,制表符和換行符組成,空格一般用來分隔ID,NUM,運算符,界符和關鍵字,此法分析階段通常被忽略. 3 各種單詞符號對應的種別碼如表所示

In this article, I will explain how to create UDP packets and then send them to a remote server through the Internet using WinPCap for Windows. The code has been tested to work with Windows XP SP2 and Vista SP1 on Linksys routers, and on Toshiba modems connected directly to the Internet. Please note that the code here is very minimalistic, and can be greatly expanded depending on your needs. The reason I use WinPCap in this article is that it solves the issue of Winsock for Windows (XP SP2 and above) not allowing raw UDP packets to be sent (in Linux, you can just use regular sockets). With WinPcap, it is possible to specify your own source IP and source hardware addresses in packets.

if the method is to be made void, then it cannot have a return statement, all it can do is set the value. Your SeatReserved variable is already a global variable, so what you have in the last post will work, it is known as a set or setter method. All it does is set a value, usually these are done accross classes.
