可我是这样把他全打出来的：

#include<conio.h>
#include<stdio.h>

void main(void)
{
int color=0;
for(color=0;color<8;color++)
{
textbackground(color);
cprintf("This is color %d\r\n",color);
cprintf("Press any key to continue\r\n");
getch();
}
}

他老报错
error C2065: 'textbackground' : undeclared identifier
这个错

你自己查查你编译器的include 文件
