General Development "Coming from a background in higher-level languages like Ruby, Scheme, or Haskell, learning C can be challenging. In addition to having to wrestle with C's lower-level features like manual memory management and pointers, you have to make do without a REPL. Once you get used to exploratory programming in a REPL, having to deal with the write-compile-run loop is a bit of a bummer. It occurred to me recently that I could use gdb as a pseudo-REPL for C. I've been experimenting with using gdb as a tool for learning C, rather than merely debugging C, and it's a lot of fun. My goal in this post is to show you that gdb is a great tool for learning C. I'll introduce you to a few of my favorite gdb commands, and then I'll demonstrate how you can use gdb to understand a notoriously tricky part of C: the difference between arrays and pointers."

REPL - a key to success

Yep thats called experience. At some point you discover that you have a fancy algorithm or idea in your head, you sit down., write a program, compile, run , and discover that it works perfectly the first time. Thats great feeling!

And even after some years of working with this, having a program work on the first try is still rare enough that it feels like a victory every time it happens. ;)
