程序代码：

     快学了一个月的C语言了，最近想写一个以前小霸王，上面的坦克大战，再发射子弹的代码上遇到了一个小麻烦。
     我是用getch(),来接受键盘的控制的。
       比如: 
            1  当我用'j'来接受发射子弹的时候，然后程序进入打印清除的循环。（这个时候我必须等到子弹发出去，消失后才能，移动自己的人物）
            2  当子弹在移动的过程中，我如果按方向键移动的话，人物不会重新打印，而是记录按键，等到子弹循环消失后，直接打印在，记录按键最后一个上（瞬移）
            3  是我逻辑错误还是没有用对？（getch()）？;
            4  希望大家多提提意见_格式_排版_还有各种不好的地方都提出来;
