下面是作者的说明：

我想做类似上图的功能，经过一番研究，我做出来了。

实现的代码如下：
// console.cpp
//
#include "console.h"

using namespace std;

//
// Clears the screen
//
void clrscr()
{
COORD coordScreen = { 0, 0 };
DWORD cCharsWritten;
CONSOLE_SCREEN_BUFFER_INFO csbi;
DWORD dwConSize;
HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);

GetConsoleScreenBufferInfo(hConsole, &csbi);
dwConSize = csbi.dwSize.X * csbi.dwSize.Y;
FillConsoleOutputCharacter(hConsole, TEXT(@# @#),
dwConSize,
coordScreen,
&cCharsWritten);
GetConsoleScreenBufferInfo(hConsole, &csbi);
FillConsoleOutputAttribute(hConsole,
csbi.wAttributes,
dwConSize,
coordScreen,
&cCharsWritten);
SetConsoleCursorPosition(hConsole, coordScreen);
}

//
// Moves the cursor to x, y in console window
// ie x=left\right y=top\bottom
//
void gotoxy(int x, int y)
{
COORD point;
point.X = x; point.Y = y;
SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE),
point);
}

//
// Set text and background colors
//
void setrgb(int color)
{
switch (color)
{
case 0: // White on Black
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),
FOREGROUND_INTENSITY | FOREGROUND_RED |
FOREGROUND_GREEN | FOREGROUND_BLUE);
break;
case 1: // Red on Black
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),
FOREGROUND_INTENSITY | FOREGROUND_RED);
break;
case 2: // Green on Black
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),
FOREGROUND_INTENSITY | FOREGROUND_GREEN);

break;
case 5: // Magenta on Black
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),

FOREGROUND_BLUE);
break;
case 6: // Cyan on Black
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),
FOREGROUND_INTENSITY | FOREGROUND_GREEN |
FOREGROUND_BLUE);
break;
case 7: // Black on Gray
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),
BACKGROUND_INTENSITY | BACKGROUND_INTENSITY);
break;
case 8: // Black on White
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),
BACKGROUND_INTENSITY | FOREGROUND_INTENSITY |
BACKGROUND_RED | BACKGROUND_GREEN |
BACKGROUND_BLUE);
break;
case 9: // Red on White
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),
BACKGROUND_INTENSITY | FOREGROUND_INTENSITY |
BACKGROUND_RED | BACKGROUND_GREEN |
BACKGROUND_BLUE |
FOREGROUND_RED);
break;
case 10: // Green on White
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),
BACKGROUND_INTENSITY | FOREGROUND_INTENSITY |
BACKGROUND_RED | BACKGROUND_GREEN |
BACKGROUND_BLUE | FOREGROUND_GREEN);
break;
case 11: // Yellow on White
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),
BACKGROUND_INTENSITY | FOREGROUND_INTENSITY |
BACKGROUND_RED | BACKGROUND_GREEN |
BACKGROUND_BLUE | FOREGROUND_RED |
FOREGROUND_GREEN);
break;
case 12: // Blue on White
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),

break;
case 15: // White on White
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),
BACKGROUND_INTENSITY | FOREGROUND_INTENSITY |
BACKGROUND_RED | BACKGROUND_GREEN |
BACKGROUND_BLUE | FOREGROUND_RED |
FOREGROUND_GREEN | FOREGROUND_BLUE);
break;
default : // White on Black
SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),
FOREGROUND_INTENSITY | FOREGROUND_RED |
FOREGROUND_GREEN | FOREGROUND_BLUE);
break;
}
}
