What is data structure in C with example?

Linear data structures in C store the data in a sequential or linear fashion. The memory location of each element stored can be accessed sequentially. The elements may not be present adjacently in the memory, however, each element is attached to the next element in some way. Example - arrays, linked lists, stacks, etc.

Can a list contain elements of a specified type?

List<T> can contain elements of the specified type. It provides compile-time type checking and doesn't perform boxing-unboxing because it is generic. Elements can be added using the Add (), AddRange () methods or collection-initializer syntax. Elements can be accessed by passing an index e.g. myList [0].

List<T> Characteristics

Creating A List

• The List<T>is a generic collection, so you need to specify a type parameter for the type of data it can store. The following example shows how to create list and add elements. In the above example, List<int> primeNumbers = new List<int>(); creates a list of int type. In the same way, cities and bigCities are string type list. You can then add eleme...
