c++关于设置设置控制台背景及字体颜色

在包含里面加上#include<stdlib.h>
然后调用system("color 3f");
颜色属性由两个十六进制数字指定 -- 第一个为背景，第二个则为前景。每个数字可以为以下任何值之一:
    0 = 黑色       8 = 灰色
    1 = 蓝色       9 = 淡蓝色
    2 = 绿色       A = 淡绿色
    3 = 湖蓝色     B = 淡浅绿色
    4 = 红色       C = 淡红色
    5 = 紫色       D = 淡紫色
    6 = 黄色       E = 淡黄色
    7 = 白色       F = 亮白色

1.设置控制台输出行数和列数

system("mode con:cols=100 lines=20000");

2.改变下一个输出或者输入字体和背景的颜色

采用SetConsoleTextAttribute函数，如
White on Black：
        SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |
            FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE);
Red on Black：
        SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |
            FOREGROUND_RED);
Green on Black：
        SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |
            FOREGROUND_GREEN);
Yellow on Black：
        SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |
            FOREGROUND_RED | FOREGROUND_GREEN);
Blue on Black：
        SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |
            FOREGROUND_BLUE);
Magenta on Black：
        SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |
            FOREGROUND_RED | FOREGROUND_BLUE);
Cyan on Black：
        SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY |
            FOREGROUND_GREEN | FOREGROUND_BLUE);
Black on Gray：
        SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),BACKGROUND_INTENSITY |
            BACKGROUND_INTENSITY);
Black on White：
        SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),BACKGROUND_INTENSITY |
            FOREGROUND_INTENSITY | BACKGROUND_RED | BACKGROUND_GREEN | BACKGROUND_BLUE);
Red on White：
        SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),BACKGROUND_INTENSITY |
            FOREGROUND_INTENSITY | BACKGROUND_RED | BACKGROUND_GREEN | BACKGROUND_BLUE |
            FOREGROUND_RED);
等等。
需要引入头文件：
windows.h
函数原型：
BOOL SetConsoleTextAttribute( HANDLE hConsoleOutput, WORD wAttributes );
wAttributes 的取值含义对应如下：

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.
