Why should we? What "shortcomings"? You mean, like you have to free
what you malloc? That's not a "shortcoming", that's just laziness. On the
other hand, you are right - *not* keeping track of memory necause it's just
a "run-and-exit" program is also programmer laziness.

It's easy enough to write routines that will do the memory management stuff
for you, and the C program would *not* be much more complex, nor would it
be much more error prone. Just because you don't want to, or don't have the
time, is no reason to try and trash C.

Oh, stop it before it becomes a religious issue. You are right, but only from
your own perspective. From my perspective, from someone who has written
literally thousands of lines of production C, it's *always* an issue. People
who ignore performance or memory issues are fools who assume that everyone
is going to be running their code on the latest PIII with a gig of RAM.
