说明： 1） 输入设备为4*4矩阵键盘，分别代表0~F；
2） 输出设备为四位数码显示管，初始值显示0000，当按下某一键时，最右边的一位数码显示管显示最新一次所按按键的数值，而之前的显示值左移，例如，第一次按‘1’键，则显示0001；第二次按‘3’键，则显示0013；第三次按‘5’键，则显示0135；第四次按‘7’键，则显示1357；第五次按‘9’键，则显示3579，第四次按‘F’键，则显示579F等等
(1) input device for the 4* 4 matrix keyboard, representing 0 ~ F 2) output device for the four digital display tubes, showed that the initial value of 0000, when the press of a button, it is the right of possession of a digital display according to the latest show by the numerical keys, and left before the display value, for example, the first time by the' 1 ' key, it shows 0001 the second time by the' 3' key, it shows 0013 the third time in accordance with' 5 ' button, it shows 0135 the fourth time by the' 7 ' key, it shows 1357 the fifth time by the' 9' key, it shows 3579, the fourth time by the ' F' keys, and so showed 579F)
