c語言編譯器,跨平臺,4.2版本
lcc version 3.x is described in the book "A Retargetable C Compiler:
Design and Implementation" (Addison-Wesley, 1995, ISBN 0-8053-1670-1).
There are significant differences between 3.x and 4.x, most notably in
the intermediate code. For details, see

本文件為用C語言實現的可實現廣義異或問題的bp神經網絡算法。該問題是對標準異或問題的推廣。在標準異或問題中,輸入X1和X2取離散量-1或+1,在廣義異或問題中,輸入(X1,X2)可以在區間[-1,+1] X [-1, +1]內任意取值,而輸出為Y=sign(x1,x2),其中sign()為符號函數,在區間[-1,+1] X [-1, +1]內隨機產生500個訓練樣本.本程序用標準BP網實現該分類問題.
C51的一些誤區和注意事項(ZT)
1)C忌諱絕對定位。 常看見初學者要求使用_at_,這是一種謬誤,把C當作ASM看待了。在C中變量
的定位是編譯器的事情,初學者只要定義變量和變量的作 用域,編譯器就把一個固定地址給這個
變量。怎么取得這個變量的地址?要用指針。比如unsigned char data x 后,x的地址就是...
