## Construct a Simple Query

Realm offers an expressive and intuitive way for querying data. Here's a simple example of querying for all `Person` objects and filtering the result based on age.

```cpp
int main() {
auto realm = realm::open<Person, Dog>({.path=path});
auto results = realm.objects<Person>().where("age > $0", {17});

for (const auto& person : results) {
std::string name = person.get_property<std::string>("name");
int age = person.get_property<int>("age");
std::string dogPurchasePower = (age >= 18) ? "can legally buy a dog in California" : "cannot legally buy a dog in California";
std::cout << "Customer " << name << " is " << age << " and " << dogPurchasePower << std::endl;
}

return 0;
}
```

## Building Realm

In case you don't want to use the precompiled version, you can build Realm yourself from source.
