#include <conio.h>
void main(void)
{
int color;
for (color = 0; color < 8; color++)
  {
  textbackground(color);/*设置文本的背景颜色*/
  cprintf("This is color %d\r\n", color);
  cprintf("Press any key to continue\r\n");
  getch();/*输入字符看不见*/
  }
}
我按照网上 做了这个
但是
warning C4013: 'textbackground' undefined; assuming extern returning int

32.obj : error LNK2001: unresolved external symbol _textbackground
Debug/32.exe : fatal error LNK1120: 1 unresolved externals
