[控制台单调的颜色只有黑白两种，看起来多少难免有些单调。在没学图形化编程之前，每天看着控制台程序难免会枯燥无味。
不过，利用SetConsoleTextAttribute函数可以设置控制台的前景色和背景色。]

*用法：

#include <windows.h>
int main(int argc, char *argv[]){
    HANDLE hOut;
    hOut = GetStdHandle(STD_OUTPUT_HANDLE);
    SetConsoleTextAttribute(hOut, x);  //x=0-255
    SetConsoleTextAttribute(hOut, 0x0007); //黑底白字  或者x=15 
} 

首先上个小程序看下

#include <conio.h>
#include <stdio.h>
#include <windows.h>
int main(int argc, char *argv[])
{
    HANDLE hOut;
    hOut = GetStdHandle(STD_OUTPUT_HANDLE);
    int i;
    for (i = 1; i < 255 ; i ++ )
    {
        SetConsoleTextAttribute(hOut, i);
        printf("%3d\t",i);
    }
    printf("\n");
    SetConsoleTextAttribute(hOut, 0x0007);
    printf("演示结束");
    getch();  //用getch();会等待你按下任意键，再继续执行下面的语句；位于conio.h 头文件 
              //用ch=getch();会等待你按下任意键之后，把该键字符所对应的ASCII码赋给ch,再执行下面的语句。
    return 0;
}

结果：

①效果图：（颜色可以混合，遵循配色原理）
