People sometimes ask just exactly what it is
I do as a programmer. It's hard to explain without lots of boring background
information about processors, operating systems, compilers, binary
numbering systems, and so on which no one ever wants to hear. But it's easy enough to show you an
example. Here's some actual C++ code from an application I wrote recently. So what I do is sit at my computer, think for a
bit, and then type a bit, and repeat, for hours on end. Sometimes I do web searches over
and over and over, looking for sample code and other assistance. Almost makes
accounting sound interesting, doesn't it? Actually, writing software is fun—It's
like building cool new machines without ever getting your hands dirty.
