training

[Michael Havens]

I think I'll take Kevin's advice. After googling the differences between OO
and procedural programming it looks to me as if the natural progression for
a beginner would be to learn bash and then learn Ruby. Would trying to
learn both at the same time be wise or not? You know, finding good teaching
material can be so difficult; could someone recommend a good pdf or
something that teaches Kevin's  recommendation?

The reason I'm taking this advice is after trying to compile the second
program I kept getting errors and I had no idea what they were saying. (see
below). I think what it is saying is that the error is in line 28 character
3. But it looks exactly like the instructions are telling me to make it! [
'exit(1);' ] (w/o the square brackets or apostrophes).

argexample2.c: In function ‘main’:
argexample2.c:28:3: warning: incompatible implicit declaration of built-in
function ‘exit’ [enabled by default]
