Back to Procedural Programming

Below is the complete code for the Back to Procedural Programming Try It Out! problem.

List<Person> parentsOfTeenagers = new List<Person>();

foreach (Person person in people)
{
    foreach (Person child in person.Children)
    {
        if (child.Age > 13 && child.Age < 30)
        {
            parentsOfTeenagers.Add(person);
        }
    }
}

Overall, this isn’t too bad. It’s still fairly understandable, though I’d say it’s substantially less clear than the original LINQ query. It’s definitely longer, and involves more nested statements.
