The following code shows how a `out_of_range` exception can be caught.
|
||||
|
||||
```cpp
|
||||
--8<-- "examples/out_of_range.cpp"
|
||||
#include <iostream>
|
||||
#include <nlohmann/json.hpp>
|
||||
|
||||
using json = nlohmann::json;
|
||||
|
||||
int main()
|
||||
{
|
||||
try
|
||||
{
|
||||
// calling at() for an invalid index
|
||||
json j = {1, 2, 3, 4};
|
||||
j.at(4) = 10;
|
||||
}
|
||||
catch (const json::out_of_range& e)
|
||||
{
|
||||
// output exception information
|
||||
std::cout << "message: " << e.what() << '\n'
|
||||
<< "exception id: " << e.id << std::endl;
|
||||
}
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
Output:
|
||||
|
||||
```json
|
||||
--8<-- "examples/out_of_range.output"
|
||||
message: [json.exception.out_of_range.401] array index 4 is out of range
|
||||
exception id: 401
|
||||
|
||||
```
