## Examples

??? example

    The example shows how JSON Pointers can be implicitly converted to strings.
     
    ```cpp
    #include <iostream>
    #include <nlohmann/json.hpp>
    
    using json = nlohmann::json;
    
    int main()
    {
        // different JSON Pointers
        json::json_pointer ptr1("/foo/0");
        json::json_pointer ptr2("/a~1b");
    
        // implicit conversion to string
        std::string s;
        s += ptr1;
        s += "\n";
        s += ptr2;
    
        std::cout << s << std::endl;
    }
    
    ```
    
    Output:
    
    ```json
    /foo/0
    /a~1b
    
    ```
