.PP
\fBTemplate Parameters\fP
.RS 4
\fI_Tp\fP Type of element\&. 
.br
\fI_Sequence\fP Type of underlying sequence, defaults to deque<_Tp>\&.
.RE
.PP
Meets many of the requirements of a \fCcontainer\fP, but does not define anything to do with iterators\&. Very few of the other standard container interfaces are defined\&.
.PP
This is not a true container, but an \fIadaptor\fP\&. It holds another container, and provides a wrapper interface to that container\&. The wrapper is what enforces strict first-in-last-out stack behavior\&.
.PP
The second template parameter defines the type of the underlying sequence/container\&. It defaults to std::deque, but it can be any type that supports \fCback\fP, \fCpush_back\fP, and \fCpop_back\fP, such as std::list, std::vector, or an appropriate user-defined type\&.
.PP
Members not found in \fInormal\fP containers are \fCcontainer_type\fP, which is a typedef for the second Sequence parameter, and \fCpush\fP, \fCpop\fP, and \fCtop\fP, which are standard stack/FILO operations\&.

.PP
Default constructor creates no elements\&. 
.SH "Member Function Documentation"
.PP 
.SS "template<\fBtypename\fP _Tp , \fBtypename\fP _Sequence  = deque<_Tp>> bool \fBstd::stack\fP< _Tp, _Sequence >::empty () const\fC [inline]\fP"
Returns true if the stack is empty\&. 
.SS "template<\fBtypename\fP _Tp , \fBtypename\fP _Sequence  = deque<_Tp>> \fBvoid\fP \fBstd::stack\fP< _Tp, _Sequence >::pop ()\fC [inline]\fP"

.PP
Removes first element\&. This is a typical stack operation\&. It shrinks the stack by one\&. The time complexity of the operation depends on the underlying sequence\&.
.PP
Note that no data is returned, and if the first element's data is needed, it should be retrieved before pop() is called\&. 
.SS "template<\fBtypename\fP _Tp , \fBtypename\fP _Sequence  = deque<_Tp>> \fBvoid\fP \fBstd::stack\fP< _Tp, _Sequence >::push (const value_type & __x)\fC [inline]\fP"

.PP
Add data to the top of the stack\&. 
.PP
\fBParameters\fP
.RS 4
\fI__x\fP Data to be added\&.
.RE
.PP
This is a typical stack operation\&. The function creates an element at the top of the stack and assigns the given data to it\&. The time complexity of the operation depends on the underlying sequence\&. 
.SS "template<\fBtypename\fP _Tp , \fBtypename\fP _Sequence  = deque<_Tp>> size_type \fBstd::stack\fP< _Tp, _Sequence >::size () const\fC [inline]\fP"
Returns the number of elements in the stack\&. 
.br
 
.SS "template<\fBtypename\fP _Tp , \fBtypename\fP _Sequence  = deque<_Tp>> reference \fBstd::stack\fP< _Tp, _Sequence >::top ()\fC [inline]\fP"
Returns a read/write reference to the data at the first element of the stack\&. 
.SS "template<\fBtypename\fP _Tp , \fBtypename\fP _Sequence  = deque<_Tp>> const_reference \fBstd::stack\fP< _Tp, _Sequence >::top () const\fC [inline]\fP"
Returns a read-only (constant) reference to the data at the first element of the stack\&.
