遇到To disable deprecation, use _CRT_SECURE_NO_WARNINGS

程序编译过程中遇到

 error C4996: 'localtime': This function or variable may be unsafe. Consider using localtime_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.

 : 参见“localtime”的声明

解决方法：在项目属性——命令行中添加 /D _CRT_SECURE_NO_WARNINGS
