What is C Programming Language? Basics, Introduction, History

C language is general-purpose computer programming language which is portable, procedural, structural and efficient modern programming language. It is also extremely powerful, popular, simple to use. It is structured complied programming language that was mainly developed to write an operating systems and various application. This language was developed by Computer Scientist Dennis Ritchie in 1972. 

Why and Where do we use C Language? 

C Language is a general-purpose programing language and due to it's portability, efficiency and can efficiently work on games, graphics, calculations required applications, enterprise applications. So, it is use to write the script of systems software and high complexity data manipulation software like: window, Unix is totally written in C, Linux, Metro game, Adobe, etc. 

Why is C so popular language?

C language is a popular language because it is a mother or base of all programming language. C is middle-level programming language which reduce gap between low-level and high-level programming language. It is also efficient, versatile and flexible to use memory management. So, It is excellent option for write high complexity data manipulation software. Like: Windows, Linux, Unix, Adobe, Data base, game, etc. Fact that ' today, many programming language is better than c language but does not in all platforms'.

Why is C known as C language?

C language is named as 'C language' because this language is succeeds language of other past language known as B.   

History Of C Language. 

In 1972, a great computer scientist Dennis  Ritchie written a new programming language called ' C ' language at the Bell Laboratory. It's basic ideas taken from 'ALGOl', 'BCPL' and 'B' programming languages. C Language provides all the feature of these language  and many more additional features and concepts that make it unique from other languages. 

  With the respects of time, it started evolving many different version of the this  language were released. But, at that time it become very difficult for the developers to keep up Update with the latest version for the system, which were already running under the older version. To assure that 'C' language will remain standards, American National standards Institute (ANSI) defined a commercial standard  for 'C' language in 1989, later it was approved by the international standard organisation (ISO) in 1990. C Language is also known as 'ANSI C'. 

Features of C language. 

Portable language

C Language  was able to be compiled with different compilers and it's design can run on most hardware platforms. So, it is portable Language. which means you don't have to know everything about the memory layout of your machine in order to write programs for it.

The C programming language also enables programmers to recompile their code without having any knowledge of assembly.

Built-in functions(Rich Library)

It has many functions which make easier for modern programmers to manipulate the various programs. like: printf(), while(), if(), scanf() and etc. automatically linked in by the compiler. A various of libraries exist which suggest an even greater selection of these type of command. 

Powerful and efficient language

It is a Powerful and efficient language because, it work as portable assembler and use for low-level programming and can be compiled by different compilers. It's efficiency makes easy to programmer write efficient code, and can improve runtime performance.

Quality to extend itself

It is eminently extensible. Because, it has  extended by many different languages, like: Java, python, etc. have possibility to extend C language in the same way with preprocessors like GNU Complier Collection(GCC)  or C lang. 

Open-source

It is open-source language, that's means this code is publicly available even online or offline and each programmer can modify it to manipulate their project to present better performance. 

It also enables programmers to create libraries for public purpose use based on their particular preferences.

Structured programming language

It is a structured programming language, that's means it has an opening and closing brackets for every block or define steps of code. It enable the programmer to use the extra space provided by these brackets to mention their code within each function, making everything easy to compile and simple to understand.

Middle-level language

It is a middle-level programming language. because, it can be used for low-level and high-level programming language. It's best choice for programmer because of its efficiency and portability experience.

Implementation of algorithms and data structures

It is provides best platforms for implementing the algorithms and data structures. So, it is known as low-level language. 

Procedural programming language

It is a procedural programming language, it means, it provides instructions to the computer in given order. It is known procedural because, the use of procedures and functions for tasks like input and output. It also enables the programmers to create reusable code in their compiler.

Dynamic memory allocation

It supports dynamic memory allocation, it means that a programmer can create and erase  sections of memory as required. It is an essential requirement of modern programming languages to know in advance programme how much space code will required. 

Pointer

It provides the feature of pointers. By which programmer can directly interacts with the computer memory by using the pointers and programmer can use pointers for memory, structures, functions, array, etc.

Limitations of C Language. 

Object-Oriented Programming System (OOPs)

(OOPs) is a programming concept which works on the principles of abstraction, encapsulation, inheritance, and polymorphism.

Run-time checking

At Run-time of code, programmer are not detect the errors or the bugs after each line of codes. Instead, the compiler shows all the errors after writing the whole program. So, It makes very complex the checking of code in large programs.

Namespace Implementing. 

Programmer does not implement the namespaces. A namespace is structured as a chain of commands which allow the programmer to reuse of names in different contexts. Without namespaces, programmer cannot declare two variables of the same name. But in C programming does not implement the namespace.

Low level of abstraction

It is a small and core machine language and it has minimum data hiding and exclusive visibility which affects the security of C language.

Lack of Exception Handling

When programmer compiling the code, various anomalies and bugs are occur. To find this occurs programmer use Exception Handling to catch the error and take appropriate responses. However, C does not exhibit this important feature.

Who discovered C language?

American Computer Scientist Dennis Ritchie (Dennis MacAlistair Ritchie) was developed C programming language in 1972. He was also co-developer of Unix operating system. 

Why we learn C language? 

C language is mother of all programming language. All high-level language are based on basic concepts and principles of C language. So, It is most powerful and popular high-level languages. In order to learn other high-level language(Java script, Python, etc) or To be a programmer, learn C language is highly beneficial to understand basic of language. It is use to write script of Operating system and device drivers. If you want to pursue programming career or software developer. Then, understanding of C language is required. 

To learn C language, follow our best course's with suitable examples, in order to be a programmer.
