## 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
|
|
|
|
```
|
