You typically use an indexer if the class represents a list, collection or array of objects. In your case, you could provide an indexer to provide index-based access to a teacher's students. You would use an enumerator if your data is normally accessed sequentially.

What are indexers used for?

Indexers are a syntactic convenience that enable you to create a class, struct, or interface that client applications can access as an array. The compiler will generate an Item property (or an alternatively named property if IndexerNameAttribute is present), and the appropriate accessor methods.

What is indexer and use of it?

An indexer allows an instance of a class or struct to be indexed as an array. ... Array access operator i.e ([ ]) is used to access the instance of the class which uses an indexer. A user can retrieve or set the indexed value without pointing an instance or a type member. Indexers are almost similar to the Properties.

Which among the following are the advantages of using indexers?

Which among the following are the advantages of using indexers?

What is indexer clustering in Splunk?

Indexer clusters are groups of Splunk Enterprise indexers configured to replicate each others' data, so that the system keeps multiple copies of all data. ... This means that, if one or more indexers fail, incoming data continues to get indexed and indexed data continues to be searchable.

What is the correct syntax for declaring the indexer?

To declare an indexer for a class, you add a slightly different property with the this[] keyword and arguments of any type between the brackets. Properties return or set a specific data member, whereas indexers return or set a particular value from the object instance.

Can we have static indexer in C#?

Can destructors be overloaded?

Answer: No, we cannot overload a destructor of a class in C++ programming. ... Destructor in C++ neither takes any parameters nor does it return anything. So, multiple destructor with different signatures are not possible in a class. Hence, overloading is also not possible.
