| Implementation | Primary Platform | Characteristics | |----------------|------------------|------------------| | (GCC) | Linux, Unix-like | Most common on Linux; uses old ABI ( std::string copy-on-write) historically. Dual ABI (C++11 fixes). | | libc++ (LLVM) | macOS, iOS, FreeBSD | Clean, modern design; avoids COW; easier to debug. | | MSVC STL (Microsoft) | Windows | Tight integration with Visual Studio; uses SEH for exceptions. | | libc++abi | Cross-platform | Low-level ABI support (used by libc++). | c++ runtime library

Our library will be called math_utils and will provide the following functions: October 26, 2023 Subject: Technical Overview and Analysis

The (often abbreviated as CRT) is a collection of low-level routines and functions that provide the essential infrastructure for a C++ program to execute properly on a specific operating system. While high-level code provides the logic, the runtime library handles the "behind-the-scenes" mechanics, such as memory management, exception handling, and even the initial handoff from the operating system to your main() function.
