char pbuf[1 << 20], *pp = pbuf;
void ph(const char &c) {
  if (pp - pbuf == 1 << 20) fwrite(pbuf, 1, 1 << 20, stdout), pp = pbuf;
  *pp++ = c;
}

能给个使用的例子吗

char pbuf[1 << 20], *pp = pbuf;
void ph(const char &c) {
  if (pp - pbuf == 1 << 20) fwrite(pbuf, 1, 1 << 20, stdout), pp = pbuf;
  *pp++ = c;
main(){
	push('a')
	return 0;
}

需要加什么才能正常输出
