# nlohmann::basic_json::crend

    const_reverse_iterator crend() const noexcept;

Returns an iterator to the reverse-end; that is, one before the first element. This element acts as a placeholder, attempting to access it results in undefined behavior.

## Return value

reverse iterator to the element following the last element

## Exception safety

No-throw guarantee: this member function never throws exceptions.

## Complexity

Constant.

## Examples

Example

The following code shows an example for `eend()`.

    #include <iostream>
    #include <nlohmann/json.hpp>

    using json = nlohmann::json;

    int main()
    {
        // create an array value
        json array = {1, 2, 3, 4, 5};

        // get an iterator to the reverse-end
        json::const_reverse_iterator it = array.crend();

        // increment the iterator to point to the first element
        --it;

        // serialize the element that the iterator points to
        std::cout << *it << '\n';
    }

Output:

    1
