<vector>

Defines the container class template vector and several supporting class templates.

The vector is a container that organizes elements of a given type in a linear sequence. It enables fast random access to any element, and dynamic additions and removals to and from the sequence. The vector is the preferred container for a sequence when random-access performance is at a premium. When in doubt about what container type to use, choose vector.

For more information about the class vector, see vector Class. For information about the specialization vector<bool>, see vector<bool> Class.

Parameters

• Type
  The template parameter for the type of data stored in the vector.

• Allocator
  The template parameter for the stored allocator object responsible for memory allocation and deallocation. For most cases you can ignore this parameter and just use the default allocator.

• _Left
  The first (left) vector in a compare operation

• _Right
  The second (right) vector in a compare operation.

Operators

operator! =	Tests if the vector object on the left side of the operator is not equal to the vector object on the right side.
operator<	Tests if the vector object on the left side of the operator is less than the vector object on the right side.
operator<=	Tests if the vector object on the left side of the operator is less than or equal to the vector object on the right side.
operator==	Tests if the vector object on the left side of the operator is equal to the vector object on the right side.
operator>	Tests if the vector object on the left side of the operator is greater than the vector object on the right side.
operator>=	Tests if the vector object on the left side of the operator is greater than or equal to the vector object on the right side.

Classes

vector Class

A class template of sequence containers that arrange elements of a given type in a linear arrangement and allow fast random access to any element.

Specializations

vector<bool> Class

A full specialization of the template class vector for elements of type bool with an allocator for the underlying type used by the specialization.
