C# has a #define directive. It indicates blocks of code to be compiled. Most programmers go for C# when developing desktop applications. C# programs are compiled to an intermediate language independent of the language. It provides automatic garbage collection features. Unlike C, pointers are not used in C# programming. When calling unmanaged libraries on the virtual machine, C# supports the limited use of pointers. There is no use of header files. The declaration of functions and classes are not needed. Their definition may be done in any order. The classes can be nested. Global functions or variables are not available. Static constructors initialize default values for all the variables. The C# program code is more legible due to the formalized concept of get-set methods. The use of delegates manages the events. In general, C# is much more efficient than Java and runs faster.
C# has more primitive types. In the array concept, indexers allow the access of objects. The multi-threading in C# is more simple. Unlike Java, it supports the operator overloading. The codes written in C# are much more robust, cleaner, faster and more comfortable. C# is intended to be used only in Windows operating system. Console based multiplatform applications can be written in the C# programming language. It is a more high-level language than C++. C# consists of a large framework with pre-developed components, which makes useful for server-side programming. C# is full of features that make programming development faster and easier, generally at the cost of flexibility and runtime performance. Boxing and unboxing are the two features that make C# a unique language. Delegates provide support for flexible implementation of callbacks. It reduces the complexity of code and the logical errors. Enumerations increase the robustness of the code. It provides type checking. C++ is better than C. C# is far superior to C++.
