👉 The GNU Compiler Collection (GCC) is a free and open-source compiler suite developed by the Free Software Foundation. It supports multiple programming languages, including C, C++, Fortran, Objective-C, and more, offering both front-end (compilers for source code) and back-end (optimizers and linkers) tools. GCC is designed to compile source code into executable programs and libraries, providing a wide range of optimization options and cross-platform capabilities. It is widely used in academic, research, and industrial settings for developing software across various platforms, from Unix-like systems to Windows through tools like MinGW and WSL.
