    operator string_t() const

Return a string representation of the JSON pointer.

## Return value

    {
        return to_string();
    }

## Notes

Deprecation

This function is deprecated in favor of `to_string` and will be removed in a future major version release.

## Examples

Example

The example shows how JSON Pointers can be implicitly converted to strings.

    #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:

    /foo/0
    /a~1b
