Will the base class constructor be automatically called?

Question

class Person
{
    public int age;
    public Person()
    {
        age = 1;
    }
}

class Customer : Person
{
    public Customer()
    {
        age += 1;
    }
         


        

Answer 1

Yes, the base class constructor will be called automatically. You do not need to add an explicit call to base() when there is a constructor with no arguments.

You can easily test this by printing out the age of the customer after construction (link to ideone with a demo).
