Even worse, if atoi() is given a string that represents a number
that's too big to hold in an int, it invokes undefined behavior.
For example, there's no telling what atoi("99999999999999999999")
will do; it could crash your program or worse.

I see. Must be a left over dinosaur like gets().

No. gets() is just unsafe regardless. atoi() can be used safely,
but why bother when you have strtol available.

In other words, it's a left over dinosaur. And so is gets(). Therefore,
it's a left over dinosaur like gets(). Which is what he said.
