## Conversions ## Conversions
An alternate loop to the example above would look like: An alternate loop to the example above would look like:
```cpp ```cpp
// ... // ...
ss::parser<ss::throw_on_error> p{"students.csv"}; ss::parser p{"students.csv"};
while (!p.eof()) { while (!p.eof()) {
const auto& [id, age, grade] = p.get_next<std::string, int, float>(); const auto& [id, age, grade] = p.get_next<std::string, int, float>();
if (p.valid()) {
std::cout << id << ' ' << age << ' ' << grade << std::endl; std::cout << id << ' ' << age << ' ' << grade << std::endl;
} }
// ... }

``` ```
The alternate example will be used to show some of the features of the library. The **`get_next`** method returns a tuple of objects specified inside the template type list. The alternate example with exceptions disabled will be used to show some of the features of the library. The **`get_next`** method returns a tuple of objects specified inside the template type list.
If a conversion could not be applied, the method would return a tuple of default constructed objects, and the **`valid`** method would return **`false`**, for example if the third (grade) column in our csv could not be converted to a float the conversion would fail.
