std::inplace_vector<T,N>::back

constexpr reference back();

constexpr const_reference back() const;

Returns a reference to the last element in the container.

If empty() is true:

• If the implementation is hardened, a contract violation occurs.
• If the implementation is not hardened, the behavior is undefined.

Return value

Reference to the last element.

Complexity

Constant.

Notes

For a non-empty container c, the expression c.back() is equivalent to *std::prev(c.end()).

Example

#include <cassert>
#include <inplace_vector>

int main()
{
    std::inplace_vector<char, 4> letters{'a', 'b', 'c', 'd'};
    assert(letters.back() == 'd');
}
