I did a lot of programming in Turbo Pascal (because it was so fast
to compile) and I liked the language OK.

I was taught data structures in Pascal and later taught using Pascal
and it was a fine teaching language.  I agree with the comment that
it is easier to use right, more guard rails.

But as you grow up, you want to take off the guard rails once in a
while and Pascal didn't let you do that.  C does that routinely,
which one could argue isn't that great, but it sure is handy.
