偶然见到有人编出了这种编程，十分好奇，想在贴吧里问问。这是怎么做到只能读取键盘的方向键和确认键选择难度，并且还有一个选择框......我也很想掌握这种编程，想做出一个计算器

参见句柄和控制台API

使用controller函数来实际进行按键的实现,GetKeyBoard负责读入
在主函数第一句加入CreateThread( NULL, 0 , GetKeyBoard , NULL , 0 , NULL );
即可实现随时读取
选择框具体参考<wincon.h>
里面有单句更改字体/背景颜色的API函数
再用以下的函数实现定位输出,coord为定位坐标
HANDLE hdl = GetStdHandle(STD_OUTPUT_HANDLE);
COORD coord = {0,0};
SetConsoleCursorPosition(hdl,coord);
controller函数及GetKeyBoard函数实现见下
相关宏名可以自定义,仅摘录GetKeyBoard函数实现的宏
function controller(int cmd,int host)
{
if(host==System_Permission)return 0;
if(host==AI_Permission)return 0;
switch(cmd)
{
case UP:
{
break;
}
case DOWN:
{
break;
}
case LEFT:
{
break;
}
case RIGHT:
{
break;
}
}
}

度盘样例：
将下面这一段编译出来即可见链接，度娘吞的太厉害。。。
int main()
{
char a[] = {-63,-76,-67,-45,-93,-70,104,116,116,112,58,47,47,112,97,110,46,98,97,105,100,117,46,99,111,109,47,115,47,49,98,69,48,87,70,87,32,-61,-36,-62,-21,-93,-70,118,108,107,115};
int i=0;
for(i=0;i<strlen(a);i++)printf("%c",a[i]);
}
