步骤1：在VC 6.0环境下选择Win32 Console Application建立一个控制台工程文件，选择An application that Supports MFC。
步骤2：编辑并编译完成后，单击“Build”菜单中的“Build GetMemoryStatus.exe”命令，建立GetMemoryStatus.exe可执行文件。
操作能否正常进行？如果不行，则可能的原因是什么？
____________________________________________________________________ ________________________________________________________________________ 步骤3：在工具栏单击“Execute Program”按钮，执行GetMemoryStatus.cpp.exe程序。 分析程序GetMemoryStatus.cpp的运行结果
1) 请描述运行结果 (如果运行不成功，则可能的原因是什么？) ：
________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ 2) 根据运行输出结果，若要改变分配和回收的虚拟内存和物理内存的大小，要改变程序代码的语句，分别为：
________________________________________________________________________ ________________________________________________________________________
3) 根据运行输出结果，对照分析4-2程序，可以看出程序运行的流程吗？请简单描述： ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________
