说明：  自动机例子，都是可执行的.c文件。包括：检测C整形变量定义（自动机）.c，检测C注释风格（自动机）.c，交通观测灯.c,交通观测灯解法1.c、交通观测灯解法2.c。对于学习自动机后自己编程有很大帮助。
(Automaton examples are executable c file. Including: to detect C integer variable definition (automatic machine) c detected C comment style (automatic machine) c, traffic observation light c, the traffic observation lamp Solution 1.c traffic observation lamp solution 2.c. Great help for learning automata programming.)
