C4996 ‘localtime‘: This function or variable may be unsafe. Consider using localtime
Question： C++ 使用localtime：
time_t timep; time(&timep); char tmp[256]; strftime(tmp, sizeof(tmp), "%Y-%m-%d %H:%M:%S", localtime(&timep)); Console::WriteLine(tmp);提示： 警告 14 warning 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.
Answer：
1, 在项目设置的C/C++选项中，把检查64位移植性去掉。 2, 方案a：使用_localtime_s, _localtime32_s, _localtime64_s这3个函数代替localtime 方案b：去掉C4996警告，比如按照提示所说 #define _CRT_SECURE_NO_WARNINGS 1 或者直接#pragma warning( disable : 4996 )
