) Because after you extend the stack, you have to put *something* in the

For the record: this is comp.lang.c.
If you extend the stack you don't have to put *anything* in the top slot.

What is inconvenient about pop() returning whatever it takes off
the stack ? push() takes two values for convenience,
pop() returns a value for convenience. And it's consistent to boot.
So, I stay by my statement, that pop() returns a value for the same
reason as push() takes two values, without stating what that reason is.
You seem to think it's convenience, fine by me.
