## Examples

??? example

    The example shows the type `string_t` and its relation to `basic_json::string_t`.
     
    ```cpp
    #include <iostream>
    #include <nlohmann/json.hpp>
    
    using json = nlohmann::json;
    
    int main()
    {
        json::json_pointer::string_t s = "This is a string.";
    
        std::cout << s << std::endl;
    
        std::cout << std::boolalpha << std::is_same<json::json_pointer::string_t, json::string_t>::value << std::endl;
    }
    
    ```
    
    Output:
    
    ```json
    This is a string.
    true
    
    ```
