引入如下代码使程序运行结果一目了然

#include <Windows.h>
#include <iostream>

static void  SetConsoleColor(WORD wAttribute)
{
    HANDLE handle = GetStdHandle(STD_OUTPUT_HANDLE);
    SetConsoleTextAttribute(handle, wAttribute);
}

inline std::ostream&  defcolor(std::ostream& ostr)
{
    SetConsoleColor(FOREGROUND_BLUE | FOREGROUND_GREEN | FOREGROUND_RED);
    return ostr;
}

inline std::ostream&  greencolor(std::ostream& ostr)
{
    SetConsoleColor(FOREGROUND_GREEN | FOREGROUND_INTENSITY);
    return ostr;
}

inline std::ostream&  bluecolor(std::ostream& ostr)
{
    SetConsoleColor(FOREGROUND_BLUE | FOREGROUND_INTENSITY);
    return ostr;
}

inline std::ostream&  redcolor(std::ostream& ostr)
{
    SetConsoleColor(FOREGROUND_RED | FOREGROUND_INTENSITY);
    return ostr;
}

inline std::ostream&  lredcolor(std::ostream& ostr)
{
    SetConsoleColor(FOREGROUND_RED);
    return ostr;
}

inline std::ostream& yellowcolor(std::ostream& ostr)
{
    SetConsoleColor(FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_INTENSITY);
    return ostr;
}

inline std::ostream& magenta(std::ostream& ostr)
{
    SetConsoleColor(FOREGROUND_RED | FOREGROUND_BLUE | FOREGROUND_INTENSITY);
    return ostr;
}

inline std::ostream& cyancolor(std::ostream& ostr)
{
    SetConsoleColor(FOREGROUND_BLUE | FOREGROUND_GREEN | FOREGROUND_INTENSITY);
    return ostr;
}

inline std::ostream& graycolor(std::ostream& ostr)
{
    SetConsoleColor(FOREGROUND_INTENSITY | FOREGROUND_INTENSITY);
    return ostr;
}

输出格式如下

std::cout << redcolor << "I am RED" << defcolor << std::endl;
std::cout << bluecolor << "I am BLUE" << defcolor << std::endl;
