warning C4244: “参数”: 从“time_t”转换到“unsigned int”，可能丢失数据

    

这个警告是由于新版本的VC里time_t是64位的，而srand接受32位的unsigned int，所以会丢失数据。

改成srand((unsigned)time(NULL));强制转换time_t到unsigned int就可以了。

今天在使用随机数的时候，使用时间做种子，结果提示warning C4244: “参数”: 从“time_t”转换到“unsigned int”，可能丢失数据。原来VS中的time_t是64位的，然而default_random_engine需要32位的“unsigned int”，因此需要强制转换，比如default_random_engine e(static_cast(time(0)));。

找到stdafx.h 增加一行代码即可过滤此提示： #pragma warning(disable:4244) 重新编译即可，但是有时候不建议去除这个，有这个提示有利于写好代码，当然如果整个工程里面不会涉及大数据，过滤掉这个提示基本没问题 ...

好的，我现在需要解决用户提到的C++编译警告C4244，具体是关于将time_t类型转换为unsignedint可能导致数据丢失的问题。首先，我得回忆一下这个警告通常出现的原因。time_t在C++中通常是一个表示时间的算术类型，具体...

This leads to an ambiguous overall configuration. If you want to distribute this package, please make sure that 'multidict._multilib' is explicitly added to the `packages` configuration field. Alternatively, you can also rely on setuptools' discovery methods (for example by using `find_namespace_packages(...)`/`find_namespace:` instead of `find_packages(...)`/`find:`). You can read more about "package discovery" on setuptools documentation page: - https://setuptools.pypa.io/en/latest/userguide/package_discovery.html If you don't want 'multidict._multilib' to be distributed and are already explicitly excluding 'multidict._multilib' via `find_namespace_packages(...)/find_namespace` or `find_packages(...)/find`, you can try to use `exclude_package_data`, or `include-package-data=False` in combination with a more fine grained `package-data` configuration. You can read more about "package data files" on setuptools documentation page: - https://setuptools.pypa.io/en/latest/userguide/datafiles.html [^1]: For Python, any directory (with suitable naming) can be imported, even if it does not contain any `.py` files. On the other hand, currently there is no concept of package data directory, all directories are treated like packages. ******************************************************************************** !! check.warn(importable) copying multidict\__init__.pyi -> build\lib.win-amd64-cpython-313\multidict copying multidict\py.typed -> build\lib.win-amd64-cpython-313\multidict running build_ext building 'multidict._multidict' extension creating build\temp.win-amd64-cpython-313\Release\multidict "C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\VC\Tools\MSVC\14.43.34808\bin\HostX86\x64\cl.exe" /c /nologo /O2 /W3 /GL /DNDEBUG /MD "-IF: \Program Files\CEX-snipers\.venv1\include" "-IC:\Program Files\Python313\include" "-IC:\Program Files\Python313\Include" "-IC:\Program Files (x86)\Microsoft Visu al Studio\2022\BuildTools\VC\Tools\MSVC\14.43.34808\include" "-IC:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\VC\Auxiliary\VS\include" "-IC:\Pro gram Files (x86)\Windows Kits\10\include\10.0.22621.0\ucrt" "-IC:\Program Files (x86)\Windows Kits\10\\include\10.0.22621.0\\um" "-IC:\Program Files (x86)\Window s Kits\10\\include\10.0.22621.0\\shared" "-IC:\Program Files (x86)\Windows Kits\10\\include\10.0.22621.0\\winrt" "-IC:\Program Files (x86)\Windows Kits\10\\inclu de\10.0.22621.0\\cppwinrt" "-IC:\Program Files (x86)\Windows Kits\NETFXSDK\4.8\include\um" /Tcmultidict/_multidict.c /Fobuild\temp.win-amd64-cpython-313\Release\multidict\_multidict.obj -O2 _multidict.c C:\Users\Administrator\AppData\Local\Temp\pip-install-a_qhru6_\multidict_78331f0e380e44a190a9c08ca64c358f\multidict\_multilib/iter.h(164): warning C4244: “函数”: 从“Py_ssize_t”转换到“long”，可能丢失数据 multidict/_multidict.c(453): warning C4013: “_PyArg_ParseStackAndKeywords”未定义；假设外部返回 int multidict/_multidict.c(712): warning C4013: “Py_TRASHCAN_SAFE_BEGIN”未定义；假设外部返回 int multidict/_multidict.c(718): warning C4013: “Py_TRASHCAN_SAFE_END”未定义；假设外部返回 int multidict/_multidict.c(1650): warning C4244: “函数”: 从“uint64_t”转换到“unsigned long”，可能丢失数据 "C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\VC\Tools\MSVC\14.43.34808\bin\HostX86\x64\link.exe" /nologo /INCREMENTAL:NO /LTCG /DLL /MAN IFEST:EMBED,ID=2 /MANIFESTUAC:NO "/LIBPATH:F:\Program Files\CEX-snipers\.venv1\libs" "/LIBPATH:C:\Program Files\Python313\libs" "/LIBPATH:C:\Program Files\Python 313" "/LIBPATH:F:\Program Files\CEX-snipers\.venv1\PCbuild\amd64" "/LIBPATH:C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\VC\Tools\MSVC\14.43.34 808\lib\x64" "/LIBPATH:C:\Program Files (x86)\Windows Kits\NETFXSDK\4.8\lib\um\x64" "/LIBPATH:C:\Program Files (x86)\Windows Kits\10\lib\10.0.22621.0\ucrt\x64" " /LIBPATH:C:\Program Files (x86)\Windows Kits\10\\lib\10.0.22621.0\\um\x64" /EXPORT:PyInit__multidict build\temp.win-amd64-cpython-313\Release\multidict\_multidic t.obj /OUT:build\lib.win-amd64-cpython-313\multidict\_multidict.cp313-win_amd64.pyd /IMPLIB:build\temp.win-amd64-cpython-313\Release\multidict\_multidict.cp313-win_amd64.lib 正在创建库 build\temp.win-amd64-cpython-313\Release\multidict\_multidict.cp313-win_amd64.lib 和对象 build\temp.win-amd64-cpython-313\Release\multidict\_multidict.cp313-win_amd64.exp _multidict.obj : error LNK2001: 无法解析的外部符号 Py_TRASHCAN_SAFE_END _multidict.obj : error LNK2001: 无法解析的外部符号 Py_TRASHCAN_SAFE_BEGIN build\lib.win-amd64-cpython-313\multidict\_multidict.cp313-win_amd64.pyd : fatal error LNK1120: 2 个无法解析的外部命令 error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2022\\BuildTools\\VC\\Tools\\MSVC\\14.43.34808\\bin\\HostX86\\x64\\link.exe' failed with exit code 1120 [end of output] note: This error originates from a subprocess, and is likely not a problem with pip.

此外，我们还看到一些警告，主要是关于从size_t转换到int可能丢失数据。这是因为我们使用`players.size()`（返回size_t类型）赋值给int类型的变量。我们可以将相关变量改为size_t类型，或者进行显式转换。由于这些...

先说函数，生成随机数一般用两个函数： rand()和srand() rand() 内部用线性同余法，生成的是伪随机数 其范围为0到RAND_MAX，RAND_MAX的值由库决定。 srand() 设置rand()产生随机数时的随机数种子。随机数种子相同，rand()生成的随机数序列相同 常常使用系统时间来初始化srand()，即使用 time 函数来获得系统时间，它的返回值为从00:00 hours, Jan 1, 1970 UTC 到现在所持续的秒数，然后将 time_t 型数据转化为(unsign
