Colorizing text in the console with C++
提问by Sudantha
How can I write colored text to the console with C++? That is, how can I write different text with different colors?
如何使用 C++ 将彩色文本写入控制台？也就是说，如何用不同的颜色编写不同的文本？

Add a little Color to your Console Text
HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
// you can loop k higher to see more color choices
for(int k = 1; k < 255; k++)
{
// pick the colorattribute k you want
SetConsoleTextAttribute(hConsole, k);
cout << k << " I want to be nice today!" << endl;
}
Character AttributesHere is how the "k" value be interpreted.
字符属性下面是解释“k”值的方式。

Standard C++ has no notion of 'colors'. So what you are asking depends on the operating system.
标准 C++ 没有“颜色”的概念。所以你问的是什么取决于操作系统。
For Windows, you can check out the SetConsoleTextAttributefunction.
对于 Windows，您可以查看SetConsoleTextAttribute函数。
On *nix, you have to use the ANSIescape sequences.
在 *nix 上，您必须使用ANSI转义序列。

You can write methods and call like this
您可以编写方法并像这样调用
HANDLE hConsole;
hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
int col=12;
// color your text in Windows console mode
// colors are 0=black 1=blue 2=green and so on to 15=white
// colorattribute = foreground + background * 16
// to get red text on yellow use 4 + 14*16 = 228
// light red on yellow would be 12 + 14*16 = 236
FlushConsoleInputBuffer(hConsole);
SetConsoleTextAttribute(hConsole, col);
cout << "Color Text";
SetConsoleTextAttribute(hConsole, 15); //set back to black background and white text

Assuming you're talking about a Windows console window, look up the console functions in the MSDN Library documentation.
假设您在谈论 Windows 控制台窗口，请在 MSDN 库文档中查找控制台功能。
Otherwise, or more generally, it depends on the console. Colors are not supported by the C++ library. But a library for console handling may/will support colors. E.g. google "ncurses colors".
否则，或更一般地说，这取决于控制台。C++ 库不支持颜色。但是用于控制台处理的库可能/将支持颜色。例如谷歌“ncurses 颜色”。
For connected serial terminals and terminal emulators you can control things by outputting "escape sequences". These typically start with ASCII 27 (the escape character in ASCII). There is an ANSI standard and a lot of custom schemes.
对于连接的串行终端和终端仿真器，您可以通过输出“转义序列”来控制事物。这些通常以 ASCII 27（ASCII 中的转义字符）开头。有一个 ANSI 标准和许多自定义方案。

I'm not sure what you really want to do, but my guess is you want your C++ program to output colored text in the console, right ? Don't know about Windows, but on all Unices (including Mac OS X), you'd simply use ANSI escape sequencesfor that.
我不确定您真正想要做什么，但我猜您希望 C++ 程序在控制台中输出彩色文本，对吗？不了解 Windows，但在所有 Unices（包括 Mac OS X）上，您只需为此使用ANSI 转义序列。

On Windows 10 you may use escape sequences this way:
在 Windows 10 上，您可以通过以下方式使用转义序列：
#ifdef _WIN32
SetConsoleMode(GetStdHandle(STD_OUTPUT_HANDLE), ENABLE_VIRTUAL_TERMINAL_PROCESSING);
#endif
// print in red and restore colors default
std::cout << "3[32m" << "Error!" << "3[0m" << std::endl;
回答by cambunctious
In Windows, you can use any combination of red green and blue on the foreground (text) and the background.
在 Windows 中，您可以在前景（文本）和背景上使用红绿蓝的任意组合。
/* you can use these constants
FOREGROUND_BLUE
FOREGROUND_GREEN
FOREGROUND_RED
FOREGROUND_INTENSITY
BACKGROUND_BLUE
BACKGROUND_GREEN
BACKGROUND_RED
BACKGROUND_INTENSITY
*/
HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hConsole, FOREGROUND_BLUE | FOREGROUND_GREEN | FOREGROUND_INTENSITY);
std::cout << "I'm cyan! Who are you?" << std::endl;

The simplest way you can do is:
你可以做的最简单的方法是：
#include <stdlib.h>
system("Color F3");
Where "F" is the code for the background color and 3 is the code for the text color.
其中“F”是背景颜色的代码，3 是文本颜色的代码。
Mess around with it to see other color combinations:
弄乱它以查看其他颜色组合：
system("Color 1A");
std::cout << "Hello, what is your name?" << std::endl;
system("Color 3B");
std::cout << "Hello, what is your name?" << std::endl;
system("Color 4c");
std::cout << "Hello, what is your name?" << std::endl;

Do not use "system("Color …")" if you don't want the entire screen to be filled up with color. This is the script needed to make colored text:
如果您不想让整个屏幕充满颜色，请不要使用 "system("Color ...")"。这是制作彩色文本所需的脚本：
#include <iostream>
#include <windows.h>
int main()
{
const WORD colors[] =
{
0x1A, 0x2B, 0x3C, 0x4D, 0x5E, 0x6F,
0xA1, 0xB2, 0xC3, 0xD4, 0xE5, 0xF6
};
HANDLE hstdin = GetStdHandle(STD_INPUT_HANDLE);
HANDLE hstdout = GetStdHandle(STD_OUTPUT_HANDLE);
WORD index = 0;
SetConsoleTextAttribute(hstdout, colors[index]);
std::cout << "Hello world" << std::endl;
FlushConsoleInputBuffer(hstdin);
return 0;
}
