The C# typing system contains the following
categories: Value types Reference types Variables of the value types store data, while those
of the reference types store references to the actual data. Reference types are also referred to as objects. Value types store the data on the stack and Reference
types stores the data on the heap .

extensive set of operators that give the programmer detailed control over the
construction and evaluation of expressions. Most of C#’s operators fall into the following
categories:
