C is one of the oldest currently used programming languages and is one of the most widely used programming languages. It has been constantly used in applications that had previously coded in assembly language. This includes the UNIX computer operating system.
C has directly or indirectly influenced a lot of the later programming languages, such as C#, D, Go, Java, JavaScript, Limbo, LPC, Perl, PHP, Python, and Unix's C shell. Despite all these new languages, C still remains a popular programming language.
C#, also known as C sharp, is an object oriented programming language. C# is a multi-paradigm programming language. It includes strong typing, imperative, declarative, functional, procedural, generic, object-oriented (class-based), and component-oriented programming disciplines.
C# is based on the C programming language. It was originally developed by Anders Hejlsberg for Microsoft for use in its .NET framework. The C# language was later approved as a standard by Ecma (ECMA-334) and ISO (ISO/IEC 23270:2006). C# is one of the programming languages designed for the Common Language Infrastructure. C# is intended to be a simple, modern, general-purpose, object-oriented programming language.
