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

Removes the last element of the container.

Calling pop_back on an empty container results in undefined behavior.

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

Parameters

Return value

(none)

Complexity

Constant.

Exceptions

Throws nothing.

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]
