### Validation
You can validate a json string using the accept() method:
```cpp
bool success = json::accept("Invalid json string");
// success is false
```
It is highly recommended to call accept() before parse() when receiving json strings from an untrusted source (a web server for example) as parse() can cause fatal errors when passed malformed json.
