程序运行后会在屏幕上用triplex_font显示“press any key for set off”，下

方是用基本的线条画出的发射架（有点粗糙），即程序中的DrawGun[]函数，当按下任意键后，将在发射架上方出现一个用横线填充的飞机，同

时背景被繁星填充，此时必须按住任意键不放，否则飞机将不会发射。发射完成后，即飞机坐标小于0，将出现一句话："successfully!!!,press ESC to quit",若中途按ESC退出，则飞机Y坐标不小于0，将出现"failue,..."这句话。-Will run on the screen with triplex_font show " press any key for set off" , below are the basic lines used to draw the launchers [somewhat rough], or process DrawGun [] function, when the press any key after will be the launch pad to the emergence of a plane filled with dashes, while the background was filled with stars, this time must hold down any key, otherwise the plane will not launch. Fired after the completion of that plane coordinates less than 0, there will be one sentence: " successfully!!!, Press ESC to quit" , if the half-way exit by ESC, the plane Y coordinates of not less than 0, there will be " failue, .. . " this sentence.
