A SequenceContainer is a Container that stores objects of the same type in a linear arrangement.
The type X
satisfies SequenceContainer if.
X
satisfies Container, and Given.
T
, the element type of X
A
, the allocator type of X
: X::allocator_type
if it exists, otherwise std::allocator<T>
a
, rvalue expression of type X
p
, a valid const iterator into a
q
, a valid dereferenceable const iterator into a
q1
and q2
, two const iterators into a
such that [q1, q2)
is a valid range i
and j
, LegacyInputIterators such that [i, j)
is a valid range and that the iterators refer to elements implicitly convertible to value_type
il
, an object of type std::initializer_list<value_type>
n
, a value of type X::size_type
t
, an lvalue or const rvalue of type X::value_type
rv
, a nonconst rvalue of type X::value_type
Args
: a template parameter pack args
: a function parameter pack with the pattern Arg&&
The following expressions must be valid and have their specified effects for all sequence containers except std::array
:
expression  return type  effects  precondition  postcondition 

X(n, t)
 Constructs the sequence container holding n copies of t 
T is CopyInsertable into X 
std::distance(begin(),end()) == n 

X(i, j)
 Constructs the sequence container equal, elementwise, to the range [i,j)  T is EmplaceConstructible from *i into X (only for std::vector) If the iterators are not LegacyForwardIterators, T must be CopyInsertable. 
std::distance(begin(),end()) == std::distance(i,j) 

X(il)  X(il.begin(), il.end())
 
a = il  X&  Assigns the range represented by il into a ^{[1]}  T is CopyInsertable and CopyAssignable  Existing elements of a are destroyed or assigned to 
a.emplace(p,args) 
iterator  Insert an object of type T , constructed with std::forward<Args>(args) before p 
T is CopyInsertable (for std::vector and std::deque)  Returned iterator points at the element constructed from args into a 
a.insert(p,t) 
iterator  Inserts a copy of t before p 
T is CopyInsertable (for std::vector and std::deque)  Returned iterator points at the copy of t inserted into a 
a.insert(p,rv) 
iterator  Inserts a copy of rv before p , possibly using move semantics 
T is MoveInsertable (for std::vector and std::deque)  Returned iterator points at the copy of rv inserted into a 
a.insert(p,n,t)  iterator  Inserts n copies of t before p 
T is CopyInsertable and CopyAssignable  Returned iterator points at the copy of the first element inserted into a or is p for n==0 
a.insert(p,i,j)  iterator  Inserts copies of elements in [i, j) before p  T is EmplaceConstructible and i and j are not in a (only for std::vector) If the iterators are not LegacyForwardIterators, T must be MoveInsertable and MoveAssignable.  Each iterator in [i,j) is dereferenced once. Returned iterator points at the copy of the first element inserted into a or is p for i==j 
a.insert(p, il)  iterator  a.insert(p,il.begin(),il.end())  Returned iterator points at the copy of the first element inserted into a or is p if il is empty. 

a.erase(q)  iterator  Erases the element pointed to by q 
(std::deque, std::vector) T is MoveAssignable  Returned iterator points at the element that was immediately following q prior to erasure, or a.end() if no such element exists. 
a.erase(q1,q2)  iterator  Erases elements in [q1,q2)

(std::deque, std::vector) T is MoveAssignable
 Returned iterator points at the element that was pointed by q2 prior to any erasure, or a.end() if no such element exists. 
a.clear()  void  Destroys all elements in a
 All references, pointers, and iterators are invalidated, including the end iterator. 

a.assign(i,j)  void  Replaces elements in a with a copy of [i, j) 
T is EmplaceConstructible and i , j not in a (std::vector) If not LegacyForwardIterator.  Each iterator in [i,j) is dereferenced once 
a.assign(il)  void  a.assign(il.begin(),il.end())  
a.assign(n,t) 
void  Replaces elements in a with n copies of t 
T is CopyInsertable and CopyAssignable

Additionally, for every sequence container, the constructor template that takes two input iterators and the member function template overloads of insert()
, append()
, assign()
, replace()
that take two input iterators do not participate in overload resolution if the corresponding template argument does not satisfy LegacyInputIterator.
stores and manipulates sequences of characters (class template)
