how to read the top element in stack?
hi all.
i want to ask something about stack.
my assignment require me to do the bracket checking.
for example if i find ( or { , i push it into a stack.
then if i find } or ), i pop the element that i pushed into the stack before.
how do i read the element in the top??
i've tried this way.
but it cannot be compiled.
anybody know about this? thanks. :)

s.top() == '{' but it cannot be compiled.

top() should work assuming you're using the STL stack.
What error are you getting? Can you clarfiy what kind of stack you're using (is it the STL stack?) What is it a stack of? A stack of chars?

a really dumb question, but do you have the above statement within the if-statement?...
