You should already have the sources in your compiler installation. If you are using an IDE with a "jump to include file" command, select any STL header and jump to it. If you are using some kind of UNIX, look in /usr/include/c++. See where that STL header includes other headers and recurse :v) .
您的编译器安装中应该已经有了源代码。如果您使用带有“跳转到包含文件”命令的 IDE，请选择任何 STL 标头并跳转到它。如果您使用的是某种 UNIX，请查看/usr/include/c++. 查看该 STL 标头在哪里包含其他标头和递归 :v) 。

libc++is the C++ Standard Library of LLVM.
All of the code in libc++ is dual licensed under the MIT license and the UIUC License (a BSD-like license).
libc++ 中的所有代码都获得了 MIT 许可和 UIUC 许可（类似 BSD 的许可）的双重许可。
- Correctness as defined by the C++11 standard.
- Fast execution.
- Minimal memory use.
- Fast compile times.
- ABI compatibility with gcc's libstdc++ for some low-level features such as exception objects, rtti and memory allocation.
- Extensive unit tests.
- C++11 标准定义的正确性。
- 快速执行。
- 最少的内存使用。
- 快速编译时间。
- ABI 与 gcc 的 libstdc++ 兼容，用于一些低级功能，例如异常对象、rtti 和内存分配。
- 广泛的单元测试。

This is it :
就是这个 ：
https://github.com/gcc-mirror/gcc/tree/master/libstdc%2B%2B-v3
https://github.com/gcc-mirror/gcc/tree/master/libstdc%2B%2B-v3
As a part of gcc source code
作为 gcc 源代码的一部分
https://github.com/gcc-mirror/gcc
https://github.com/gcc-mirror/gcc
that's the std library for c++
这是 C++ 的标准库

For Win10x64 with VS2017 default install paths,the source code are here:
对于 VS2017 默认安装路径的 Win10x64，源代码在这里：
part1:VCRuntime,which include code that will change for every version of Visual Studio,it contains function like the CRT entry point "mainCRTStartup",the code are here:
第1部分：VCRuntime，其中包含随Visual Studio不同版本而变化的代码，包含CRT入口点“mainCRTStartup”等功能，代码如下：
C:\Program Files (x86)\Microsoft Visual Studio17\Enterprise\VC\Tools\MSVC.16.27023\crt\src
part2:C standard library,which include code that is stable over generations of Visual Studio,like the function fopen,and it also contains stable CRT functions like _initterm,the code are here:
第2部分：C标准库，包括在Visual Studio几代稳定的代码，如fopen函数，还包含稳定的CRT函数如_initterm，代码在这里：
C:\Program Files (x86)\Windows Kits\Source.0.17763.0\ucrt
i.e. this part has been moved to Windows SDK,distributed with Windows instead of Visual Studio.
即这部分已移至 Windows SDK，随 Windows 而不是 Visual Studio 分发。

In Visual Studio if you interesting in concrete(specific) STL-element implementation (for example, any function), right click on its mention in your code and chose "Go to Definition" in context menu. (Or place cursor on this mention and push "F12")
在 Visual Studio 中，如果您对具体的（特定的）STL 元素实现（例如，任何函数）感兴趣，请右键单击代码中的提及并在上下文菜单中选择“转到定义”。（或将光标置于此提及并按“F12”）
