  2 + 控制台应用程序：merge_av 项目概述
  3 +========================================================================
  4 +
  5 +应用程序向导已为您创建了此 merge_av 应用程序。
  6 +
  7 +本文件概要介绍组成 merge_av 应用程序的每个文件的内容。
  8 +
  9 +
  10 +merge_av.vcxproj
  11 + 这是使用应用程序向导生成的 VC++ 项目的主项目文件，其中包含生成该文件的 Visual C++ 的版本信息，以及有关使用应用程序向导选择的平台、配置和项目功能的信息。
  12 +
  13 +merge_av.vcxproj.filters
  14 + 这是使用“应用程序向导”生成的 VC++ 项目筛选器文件。它包含有关项目文件与筛选器之间的关联信息。在 IDE 中，通过这种关联，在特定节点下以分组形式显示具有相似扩展名的文件。例如，“.cpp”文件与“源文件”筛选器关联。
  15 +
  16 +merge_av.cpp
  17 + 这是主应用程序源文件。
  18 +
  19 +/////////////////////////////////////////////////////////////////////////////
  20 +其他标准文件:
  21 +
  22 +StdAfx.h, StdAfx.cpp
  23 + 这些文件用于生成名为 merge_av.pch 的预编译头 (PCH) 文件和名为 StdAfx.obj 的预编译类型文件。
  24 +
  25 +/////////////////////////////////////////////////////////////////////////////
  26 +其他注释:
  27 +
  28 +应用程序向导使用“TODO:”注释来指示应添加或自定义的源代码部分。
