C#- New features Simple


One thing you definitely wouldn't attribute to C++ is that learning it is simple. This is not so with C#. The foremost goal for this programming language was simplicity. Many features—or the lack thereof—contribute to the overall simplicity of C#.

Pointers are a prominent feature that is missing in C#. By default, you are working with managed code, where unsafe operations, such as direct memory manipulation, are not allowed. I don't think any C++ programmer can claim never to have accessed memory that didn't belong to him via a pointer.

Closely related to the pointer "drama" is operator "madness." In C++, you have ::, ., and -> operators that are used for namespaces, members, and references. For a beginner, operators make for yet another hard day of learning. C# does away with the different operators in favor of a single one: the . (the "dot"). All that a programmer now has to understand is the notion of nested names.

You no longer have to remember cryptic types that originate from different processor architectures—including varying ranges of integer types. C# does away with them by providing a unified type system. This type system enables you to view every type as an object, be it a primitive type or a full-blown class. In contrast to other programming languages, treating a simple type as an object does not come with a performance penalty because of a mechanism called boxing and unboxing. Boxing and unboxing is explained later in detail, but basically, this technique provides object access to simple types only when requested.
