控制檯單調的顏色只有黑白兩種，看起來多少難免有些單調。在沒學圖形化程式設計之前，每天看著控制檯程式難免會枯燥無味。 不過，利用SetConsoleTextAttribute函式可以設定控制檯的前景色和背景色。

閒言少敘，書歸正傳。

①效果圖：（顏色可以混合，遵循配色原理）

#include <windows.h>
#include <iostream>
using namespace std;
 
 
int main()
{
    HANDLE hOut;
 
 
    hOut = GetStdHandle(STD_OUTPUT_HANDLE);
 
 
    SetConsoleTextAttribute(hOut,
                            FOREGROUND_RED | 
                            FOREGROUND_GREEN);
    cout << "This text is yellow." << endl;
 
 
    SetConsoleTextAttribute(hOut,
                            FOREGROUND_GREEN | 
                            FOREGROUND_BLUE);
    cout << "This text is cyan." << endl;
 
 
    SetConsoleTextAttribute(hOut,
                            FOREGROUND_BLUE | 
                            FOREGROUND_RED);
    cout << "This text is magenta." << endl;
 
 
    SetConsoleTextAttribute(hOut,
                            FOREGROUND_RED | 
                            FOREGROUND_GREEN | 
                            FOREGROUND_BLUE);
