What Are The Reasons To Learn C #?

By The Editorial Team

On June 11, 2019

In Snippets

The C # offers various basic and advanced C # concepts. C # language is both for beginners and professionals. C # is a .Net Framework programming language.

The C # consist all C # themes, control instructions, objects and classes, inheritance, constructor, destructor, this, static, sealed, polymorphism, abstraction, abstract type, interface, namespace, encapsulation, properties, indexer, arrays, strings, regular expressions, exception handling, multiple sub-processes, IO files, collections, etc. C # is a general-purpose, object-oriented programming language that refers as “C sharp”. It was developed by Microsoft led by Anders Hejlsberg and his team members within the the.Net initiative and permit by the European Association of Computer Manufacturers (ECMA) and the International Standards Organization (ISO). C # is famous amongst the languages for Common Language Infrastructure, and the latest version of C # is version 7.2. C # is very much related to Java syntactically and is simple for users who have the basic knowledge of C, C ++ or Java.

A bit of.Net Framework

The .Net applications are multiway platform applications, and the Framework can utilize from languages such as C ++, C #, Visual Basic, COBOL, etc. It is planned in a way so that other languages can use it.

Why #?

C # has various other reasons to be famous and in demand. Some of the reasons are mentioning below:

1. Easy to start: C sharp is high-level language, so it is similar to additional popular programming languages such as C, C ++ and Java and, therefore, it is easy to learn for everyone.

2. Widely used to develop desktop and web applications: C # is broadly used to expand web applications and desktop applications. It is single, and mainly popular languages utilize in the professional desktop. If someone wants to build Microsoft applications, C # is the language.

3. Community: the more significant the community, the better the measure that new tools and software will be developed to improve it. C # has a vast community, so the developments are made to exist in the system and not turn into extinct.

4. Game development: C # is broadly utilized in game development and will carry on dominating. C # incorporates with Microsoft and, therefore, has a broad target audience. The features of C # like automatic garbage collection, interfaces, object orientation, etc. make C # a trendy game development language.

Starting with programming in C #:

Find a compiler:

There are several online IDEs, like GeeksforGeeks ide, CodeChef ide, etc., which can be utilized to run C # programs without installing.

Windows: Since the C # produces within the Microsoft .NET framework initiative, it offers several IDE to execute C # programs: Microsoft Visual Studio, Visual Studio Express, Visual Web Developer

Linux: Mono can be utilized to run C # programs on Linux.

Programming in C #:

Since C # is very similar to other syntactic languages, it is simple to code and learn in C #.

Programs can be written in C # in any text editors such as Notepad ++, gedit, etc. or in any of the compilers. After printing the code, save the particular file with the extension cs.

Reasons to learn C sharp

Modernized language

C # is an add-on version of C ++. Previously programmers had the C language, which utilized. C ++ started adding orientation to objects in C, and C ++ became the “real” application creation language for Windows (according to C ++ developers). C ++ was utilize to write infrastructure and applications which is low level, while Visual Basic developers use to write business applications.

C # brings VB’s rapid development pattern to the world of C ++ developers, with several clear changes. C # takes the benefits of .NET Framework, which means it has the right to use a powerful forms engine, like the VB developers, have had for many years. New data types have been extra, Like the type of decimal data to perform financial computation.

Type of security

C # is a secure type, which means several things. For example, programmers cannot make use of uninitialized variables. In C ++ it is straightforward to declare a variable and then verify its value. The C # compiler will inform the user if the user tries to utilize a variable before they have initialized it to some value. With C #, user cannot go past the end of an array, as a user has been capable of doing in C and C ++ for years.

Object-oriented

In C # simple data types can be treated as objects, which mean that an int has associated methods. For example, a programmer can utilize the ToString method to get a string value for int, as shown follow.

Int Counter = 14;

Console.Write (Counter.ToString ());

Besides, literal strings can be treated as objects and support a range of methods, like Trim, ToUpper, ToLower, and many others, as shown here:

Console.Write (“hello, world” .ToUpper ());

Capabilities in several languages

C # can allow the programmer to interoperate with any other language in the .NET platform. C # also facilitates the concept of error handling in various languages.

XML Comments

C # supports the beginning of XML comments. Far from being just one more way to append comments to the code, XML comments can become the part of the documentation. Comments are positioned in XML format and can then be utilized as necessary to document the particular code. This documentation may comprise sample code, parameters and indication to other topics. Finally, it makes intellect for a developer to document their code since those comments can become documentation self-regulating of the source code. This C# general purpose language was initially produced by Microsoft to be utilized to develop applications on the Microsoft platform, and C # developers like the language because it is pleasant to apply and well designed. If a programmer wants to build apps for the Microsoft platform, then the programmer must naturally learn C #.
