把在这个小程序中用到的一些WINDOWS操作系统中的WIN32API和一些class(或者struct)的信息给出来,如下:
MSDN2001中可以查到

Character Attributes

Character attributes can be divided into two classes: color and DBCS. The following attributes are defined in the Wincon.h header file.

Attribute	Meaning
FOREGROUND_BLUE	Text color contains blue.
FOREGROUND_GREEN	Text color contains green.
FOREGROUND_RED	Text color contains red.
FOREGROUND_INTENSITY	Text color is intensified.
BACKGROUND_BLUE	Background color contains blue.
BACKGROUND_GREEN	Background color contains green.
BACKGROUND_RED	Background color contains red.
BACKGROUND_INTENSITY	Background color is intensified.
COMMON_LVB_LEADING_BYTE	Leading byte.
COMMON_LVB_TRAILING_BYTE	Trailing byte.
COMMON_LVB_GRID_HORIZONTAL	Top horizontal.
COMMON_LVB_GRID_LVERTICAL	Left vertical.
COMMON_LVB_GRID_RVERTICAL	Right vertical.
COMMON_LVB_REVERSE_VIDEO	Reverse foreground and background attributes.
COMMON_LVB_UNDERSCORE	Underscore.

The foreground attributes specify the text color. The background attributes specify the color used to fill the cell's background. The other attributes are used with DBCS.

An application can combine the foreground and background constants to achieve different colors. For example, the following combination results in bright cyan text on a blue background.

FOREGROUND_BLUE | FOREGROUND_GREEN | FOREGROUND_INTENSITY | BACKGROUND_BLUE 

If no background constant is specified, the background is black, and if no foreground constant is specified, the text is black. For example, the following combination produces black text on a white background.

BACKGROUND_BLUE | BACKGROUND_GREEN | BACKGROUND_RED 

Each screen buffer character cell stores the color attributes for the colors used in drawing the foreground (text) and background of that cell. An application can set the color data for each character cell individually, storing the data in the Attributes member of the CHAR_INFO structure for each cell. The current text attributes of each screen buffer are used for characters subsequently written or echoed by the high-level functions.

An application can use GetConsoleScreenBufferInfo to determine the current text attributes of a screen buffer and the SetConsoleTextAttribute function to set the character attributes. Changing a screen buffer's attributes does not affect the display of characters previously written. These text attributes do not affect characters written by the low-level console I/O functions (such as the WriteConsoleOutput or WriteConsoleOutputCharacter function), which either explicitly specify the attributes for each cell that is written or leave the attributes unchanged.
