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

constexpr void pop_back();

Removes the last element of 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.

Iterators and references to the last element are invalidated. The end() iterator is also invalidated.

Complexity

Constant.

Example

#include <inplace_vector>
#include <print>

int main()
{
    std::inplace_vector<int, 4> numbers{1, 2, 3};
    for (; not numbers.empty(); numbers.pop_back())
        std::println("{}", numbers);
}

[1, 2, 3]
[1, 2]
[1]
