- The
size
method returns the number of elements in the vector
- The
capacity
method returns the number of elements that could be held in currently allocated storage
- The
resize
method changes the number of elements in the vector
- The
swap
method swaps this vector's contents with those of another vector:
vector<int> p, q;
...
p.swap(q);
The ==
and !=
operators work for vectors, testing whether or not two vectors are of same size and contain the same elements
<
, <=
, >
, >=
work, doing a lexicographical comparison
