GDB (GNU Project debugger) allows you to see what is going on `inside' another program while it executes -- or what another program was doing at the moment it crashed.
- Start your program, specifying anything that might affect its behavior;
- Make your program stop on specified conditions;
- Examine what has happened, when your program has stopped;
- Change things in your program, so you can experiment with correcting the effects of one bug and go on to learn about another.
