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。-Program running on the screen using triplex_font display " press any key for set off" , the bottom line is the basic plot of the launcher (somewhat rough), the program DrawGun () function, when the press any key after the , will be the emergence of a launch pad side filled with the horizontal plane, while the background was filled with the stars, this time to hold down any key and hold, otherwise the aircraft will not launch. Launch is completed, the aircraft coordinate less than 0, there will be one sentence: " successfully!!!, Press ESC to quit" , if press ESC quit halfway, then the aircraft Y coordinates of not less than 0, there will be " failue, .. . " this sentence.
