- The C compilation process goes from source to preprocessed source to assembly to object file to binary, with the assembly step being the hardest to reverse.
- GDB is a debugger that steps through a compiled program line by line, showing changes after each step.
- Using the -g flag with gcc preserves debug symbols, and -q with gdb suppresses the copyright information.
- A breakpoint must be added in the main function to stop execution; otherwise the program runs without stopping.
- Variables can be displayed while stepping through the program.
- The return 0 statement in the main function is optional.
