Well gdb is pretty hard to use. I learned how to step through programs recently but I'm still not confident using it. The fact that printing variables is still the quickest and easiest way to gain insight into a running program's state speaks volumes.

To use gdb, I have to recompile all code with -g, run gdb, set up breakpoints and variable printing, run the program in gdb and then slowly step through it.

Alternatively, I can just write this somewhere:

  fprintf(stderr, "i = %d\n", i);
