基于vc++的图的遍历算法的动态演示系统的设计与实现(含源文件)(6)

3.2 stdafx.cpp和stdafx.h的实现

// stdafx.cpp : source file that includes just the standard includes // DFSearch.pch will be the pre-compiled header

// stdafx.obj will contain the pre-compiled type information #include \

// stdafx.h : include file for standard system include files, // or project specific include files that are used frequently, but
