C++ Runtime Library 【RECENT ✮】

| Linking Type | Binary Size | Memory Sharing | Deployment | |--------------|-------------|----------------|-------------| | ( -static-libstdc++ on GCC) | Larger | Each executable has its own copy | No runtime library dependency; safer for isolated systems. | | Dynamic (default) | Smaller | Shared across processes | Requires matching runtime .dll / .so on target machine. |

A compiled C++ application is not entirely standalone. It relies on an external library of code that must be present on the host system or linked statically within the executable. This collection of code is known as the Runtime Library. Its primary purpose is to bridge the gap between the high-level abstractions of the C++ language (classes, inheritance, polymorphism) and the low-level execution requirements of the operating system and hardware. c++ runtime library

The runtime implements the std::iostream hierarchy ( cin , cout , cerr ), buffering output and handling locale-specific formatting. | Linking Type | Binary Size | Memory
