Question

write the declaration for a default property for the customerlist class that uses an integer parameter named i to get or set a customer object at the specified index.

Answer 1

The query is about declaring a default index property in a class called CustomerList which allows accessing and modifying Customer objects at a specified index, using the parameter i of type integer.

Step-by-step explanation:

The student is asking about how to declare a default property in a class that manages a collection of objects. Specifically, they want to know how to implement a default property in the CustomerList class that allows getting or setting a Customer object at a given index using an integer parameter named i. Here's an example declaration in C#:

public Customer this[int i] {
get {
// Get logic here, such as returning the customer at position i in the list
}
set {
// Set logic here, such as setting the customer at position i in the list
}
}

This code snippet provides the index-access functionality required by the CustomerList class. The get accessor is used to retrieve the customer at the particular index, while the set accessor is responsible for assigning a Customer object to that position in the list.
