Returns an iterator to the reverse-beginning; that is, the last element.
Illustration from cppreference.com
- Complexity
- Constant.
- Requirements
- This function helps
basic_json
satisfying the ReversibleContainer requirements:
- The complexity is constant.
- Has the semantics of
reverse_iterator(end())
.
- Example
- The following code shows an example for
rbegin()
. 9 json array = {1, 2, 3, 4, 5};
15 std::cout << *it <<
'\n';
basic_json<> json
default JSON class
json_reverse_iterator< typename basic_json::iterator > reverse_iterator
a reverse iterator for a basic_json container
Output (play with this example online): 5
