2) When the host presses the start-up key, the two digital tubes display the initial time value of the countdown time of the Rush-answer "15" seconds, and enter the Rush-answer state. When one person presses the Rush-answer button, the Rush-answer buttons of other teams belong to the "rush-answer invalid" working state, and the number and 15 seconds of the Rush-answer team are displayed alternately on the two digital tubes. Countdown time; when the 15 seconds countdown arrives, the two digital tubes restore the "00" display state, and when the host press the start key again, the answer restarts.

动画的实现是通过不断修改旋转变换的角度参数（fElect1）来实现。为了不断的调用显示回调函数，需要利用GLUT库中函数：glutTimerFunc(unsigned int mescs,(*func)(int value),int value)；指定一个定时器回调函数，即经过msecs毫秒后由GLUT调用指定的函数，并将value值传递给它。
The realization of animation is achieved by continuously modifying the angle parameter (fElect1) of rotation transformation. In order to constantly call the display callback function, you need to make use of the function of the GLUT Library: glutTimerFunc (unsigned int mESCs, (*func) (int value), int value); specify a timer callback function, that is, a function specified by a GLUT call after a MSECS millisecond and passes it to it.
