C++讀取Excel
AppWizard uses "TODO:" to indicate parts of the source code you
should add to or customize.
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.
Expert C Programming: Deep C Secrets
By Peter van der Linden.
Have you ever noticed that there are plenty of C books with suggestive names like C Traps and
Pitfalls, or The C Puzzle Book, or Obfuscated C and Other Mysteries, but other programming
languages don t have books like that? There s a very good reason for this!
實現(xiàn)最優(yōu)二叉樹的構(gòu)造；在此基礎(chǔ)上完成哈夫曼編碼器與譯碼器。 假設(shè)報文中只會出現(xiàn)如下表所示的字符：
字符 A B C D E F G H I J K L M N
頻度 186 64 13 22 32 103 21 15 47 57 1 5 32 20 57
字符 O P Q R S T U V W X Y Z ， ．
頻度 63 15 1 48 51 80 23 8 18 1 16 1 6 2
要求完成的系統(tǒng)應(yīng)具備如下的功能：
1．初始化。從終端（文件）讀入字符集的數(shù)據(jù)信息，。建立哈夫曼樹。
2．編碼：利用已建好的哈夫曼樹對明文文件進行編碼，并存入目標(biāo)文件（哈夫曼碼文件）。
3．譯碼：利用已建好的哈夫曼樹對目標(biāo)文件（哈夫曼碼文件）進行編碼，并存入指定的明文文件。
4．輸出哈夫曼編碼文件：輸出每一個字符的哈夫曼編碼。
