std::inplace_vector<T,N>::back
From cppreference.com
constexpr reference back();
|
(1) | (since C++26) |
constexpr const_reference back() const;
|
(2) | (since C++26) |
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
Run this code
#include <cassert>
#include <inplace_vector>
int main()
{
std::inplace_vector<char, 4> letters{'a', 'b', 'c', 'd'};
assert(letters.back() == 'd');
}
