Questions tagged [libstdc++]

Libstdc++ is the GNU implementation of the C++ standard library and is provided as part of GCC

Libstdc++ is the GNU implementation of the C++ standard library, and implements most of C++98/C++03 standard library and in recent releases also supports most of the C++11 library.

It is the default standard library implementation used by G++ and is also often used with the Intel and Clang compilers.

Like the rest of GCC, it is Free Software and runs on a wide range of operating systems and architectures.
