3 using json = nlohmann::json;
4 
5 int main()
6 {
7  // create an array value
8  json array = {1, 2, 3, 4, 5};
9 
10  // get am iterator to one past the last element
11  json::iterator it = array.end();
12 
13  // decrement the iterator to point to the last element
14  --it;
15 
16  // serialize the element that the iterator points to
17  std::cout << *it << '\n';
18 }
