using json = nlohmann::json;

int main()
{
    // create a JSON array
    json v = {1, 2, 3, 4};

    // insert number 10 before number 3
    auto new_pos = v.insert(v.begin() + 2, 10);

    // output new array and result of insert call
    std::cout << *new_pos << '\n';
    std::cout << v << '\n';
}
:memo: cleanup after #650 As <iostream> is not included in json.hpp any more, all code examples need to include <iostream> now. 2017-07-09 17:51:38 +08:00			`#include <iostream>`
:memo: fixed examples for Wandbox As I learned in https://github.com/melpon/wandbox/issues/209, this library is already installed at Wandbox, so we need to adjust the examples to use `#include "json.hpp"` insteas of `#include <json.hpp>`. 2017-04-22 04:07:07 +08:00			`#include "json.hpp"`
added first insert functions 2015-07-13 00:28:23 +08:00
removed "using namespace" from examples 2016-01-31 03:23:14 +08:00			`using json = nlohmann::json;`
