需要用到windows.h头文件

有很多版本：
   版本1：  

void color(int ForgC,int BackC){//前景色，背景色
    WORD wColor=((BackC & OxOF)<<4)+(ForgC & OxOF);
    SetConsoleTextAttribute (GetStdHandle (STD_OUTPUT_HANDLE), wColor);
}

 版本2：

void color(int corcorcor){
    SetConsoleTextAttribute (GetStdHandle (STD_OUTPUT_HANDLE), corcorcor);
}

 版本3：

void CLOUR(int p,int x){
	//p=1  字体颜色
	//p=2  背景颜色
	//x=1  红色
	//x=2  绿色
	//x=3  蓝色
	//x=4  黄色
	//x=5  粉色
	//x=6  青色
	//x=7  白色
	//x=8  原色（灰色） 
	if(p==1){
		if(x==1)SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_RED);
		if(x==2)SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_GREEN);
		if(x==3)SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_BLUE);

		if(x==8)SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY); 
	}
	else if(p==2){
		if(x==1)SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),BACKGROUND_INTENSITY|BACKGROUND_RED);
		if(x==2)SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),BACKGROUND_INTENSITY|BACKGROUND_GREEN);

		if(x==8)SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),BACKGROUND_INTENSITY);
	}
}
