今天看了下《Windows程序设计》的第四章文本输出，现记录下学习心得。

这一章主要讲的是文本输出，今天试了下第一个例子，用到了一个叫SYSMETS.H的头文件。

头文件代码：

/*-----------------------------------------------
SYSMETS.H -- System metrics display structure
-----------------------------------------------*/

#define NUMLINES ((int) (sizeof sysmetrics / sizeof sysmetrics [0]))

struct
{
	int     iIndex ;
	TCHAR *szLabel;
	TCHAR *szDesc;
}
sysmetrics [] =
{
