@allenJo - I’ve never attended a computer programming school, and I took few computer courses of any kind. I am completely self-taught.
I started with BASIC when I was a teenager, then I graduated to C, C++ and .NET. Let me let you in on a little secret. There is a low barrier to entry for computer programming jobs.
You could conceivably get a job as a computer programmer (as I have) and never take a formal course. Of course that doesn’t mean you can be completely ignorant. You have to teach yourself.
The only time I would consider enrolling in a computer programming school (and I speak for myself here) is if I wanted to specialize in network security or database security or something like that.
In other words, something that involved more than picking up the latest language – something that was more akin to engineering. But that’s just me.
