代码如下，希望大家批评指正哈。很多没有加注释，但是有基础的人还是能看懂的 hhhhh
运行环境 vs
VS中使用fopen、sprintf等函数会出现安全问题，如下：
error C4996: ‘fopen’: This function or variable may be unsafe. Consider using fopen_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.
经测试成功的解决方法：右键工程名–>属性–>C/C++–>预处理器–>预处理器定义，编辑右边输入框加入：
_CRT_SECURE_NO_WARNINGS
保存。
