[Data structs] huffman DL : 0: 一份huff_tc.c，只能在tc下运行，因为加入了用tc图形界面直观画出树形的代码。一份是huff_vc.c,是在vc和tc下都能运行的程序，没有直观表达编码的树形结构。 [目的] 构建所输入符号（及权值）的哈夫曼树，并利用该树求出各符号的编码，深入理解最优二叉树的概念及其特性。 [问题描述] 读入各个符号及其权值，求各符号的哈夫曼编码。 [基本要求] （1）读入各个符号及其权值，建立哈夫曼树；（2）利用建立的哈夫曼树对各符号进行编码，输出编码结果。 [选做内容] 将所建立的哈夫曼树以直观的方式（树或凹入形式的表）显示。 -huff_tc.c, can only run at tc, because using the add tc intuitive graphical interface to draw tree code [Objective] To construct the input symbols (and the right value) of the Huffman tree, and use the tree to derive the coded symbols, in-depth understanding of the concept of optimal binary tree and its characteristics. [Problem Description] read into the various symbols and their weights, and Huffman coding of the symbols. [Basic requirements] (1) read into the various symbols and their weights, Huffman tree set up (2) the use of the Huffman tree for the set up of the symbol encoding, output encoding results. [Does the content of the election] will be set up by the Huffman tree to intuitive way (tree or indentations in the form of the table) shows.

[Data structs] dmp DL : 0: 虽然方式的C + +消息传递速度快于Smalltalk或Objective - C的它的方式，有时Smalltalk或Objective - C语言的灵活性是必要的。这一点本文介绍如何在C + +最少的代码实现动态消息传递是有可能的。 -Although the way C++ does message passing is much faster than the way Smalltalk or Objective-C does it, sometimes the flexibility of Smalltalk or Objective-C is required. This little article shows how it is possible to achieve dynamic message passing in C++ with minimum code.
