About GNU C
The GNU C compiler (gcc) is a free open-source compiler that compiles C code into machine language. It's part of the GNU project, which also includes tools like the GCC compiler, GDB debugger, and others.
"The most widely used compiler in the world, built from scratch by a community of developers."
Features of GNU C
- Full-featured compiler: Supports all standard C features including structs, unions, enums, and more.
- Optimizations: Provides optimization levels (-O, -Os, -O2) for performance tuning.
- Cross-compilation: Can compile code for different architectures (i.e., x86, ARM).
- Debugging: Includes a powerful debugger (gdb) for inspecting program execution.
- Libraries: Comes with many standard libraries, including math, string, and time functions.
