c++语言在cmd下输出彩色字符

c++语言在cmd下输出彩色字符

对于c语言来讲能够用system和sprintf在cmd下输出彩色字符，可是对于c++语言来讲却没有好的解决办法。

如今能够用下面的ConsoleColor.h解决这个问题

#pragma once
#include <iostream>

#include <windows.h>


inline std::ostream& blue(std::ostream &s)
{
    HANDLE hStdout = GetStdHandle(STD_OUTPUT_HANDLE);
    SetConsoleTextAttribute(hStdout, FOREGROUND_BLUE
              |FOREGROUND_GREEN|FOREGROUND_INTENSITY);
    return s;
}

inline std::ostream& red(std::ostream &s)
{
    HANDLE hStdout = GetStdHandle(STD_OUTPUT_HANDLE);
    SetConsoleTextAttribute(hStdout,
                FOREGROUND_RED|FOREGROUND_INTENSITY);
    return s;
}

inline std::ostream& green(std::ostream &s)
{
    HANDLE hStdout = GetStdHandle(STD_OUTPUT_HANDLE);
    SetConsoleTextAttribute(hStdout,
              FOREGROUND_GREEN|FOREGROUND_INTENSITY);
    return s;
}

inline std::ostream& yellow(std::ostream &s)
{
    HANDLE hStdout = GetStdHandle(STD_OUTPUT_HANDLE);
    SetConsoleTextAttribute(hStdout,
         FOREGROUND_GREEN|FOREGROUND_RED|FOREGROUND_INTENSITY);
    return s;
}

inline std::ostream& white(std::ostream &s)
{
    HANDLE hStdout = GetStdHandle(STD_OUTPUT_HANDLE);
    SetConsoleTextAttribute(hStdout,
       FOREGROUND_RED|FOREGROUND_GREEN|FOREGROUND_BLUE);
    return s;
}

struct color {
    color(WORD attribute):m_color(attribute){};
    WORD m_color;
};

template <class _Elem, class _Traits>
std::basic_ostream<_Elem,_Traits>&
      operator<<(std::basic_ostream<_Elem,_Traits>& i, color& c)
{
    HANDLE hStdout=GetStdHandle(STD_OUTPUT_HANDLE);
    SetConsoleTextAttribute(hStdout,c.m_color);
    return i;
}

在程序中包含上面这个头文件，就能够像下面这样使用彩色字符了

#include "ConsoleColor.h"

cout << white << "hello world!" << endl;
