GNU Compiler Collection or GCC is a collection of open-source compilers and toolsets that are developed by the GNU project. The GCC compiler can compile the source codes of C/C++, Objective-C, Fortran, and other programming languages into the machine code. GCC also provides code optimization and error checking of the source code during the compilation process as well as the necessary tools to debug the compiled programs. It can also compile the source codes for different system architectures like ARM 32-bit, ARM 64-bit, x86_64, PowerPC, etc.
