History of C-Programming?

The base or father of programming languages is 'ALGOL'.O It was fist introduced in 1960. 'ALGOL' was used on a large basis on European countries. 'ALGOL' introduced the concept of structured programming to the developer community. In 1967, a new computer programming language was announced called as 'BCPL' which stands for Basic Combined Programming Language. BCPL was designed and developed by Martin Richards, especially for writing system software. This was the era of programming languages. Just after three years, in 1970 a new programming language called 'B' was introduced by ken Thompson that contained multiple features of 'BCPL'. This programming language was created using UNIX operating system at AT&T and Bell Laboratories. Both the 'BCPL' and 'B' were system programming languages.

In 1972, a great computer scientist Dennis Ritchie created a new programming language called 'C' at the Bell Laboratories. It was created from 'ALGOL', 'BCPL' and 'B' programming languages. 'C' programming language contains all the features of these languages and many more additional concepts that make it unique from other languages.

'C' is a powerful programming language which is strongly associated with the UNIX operating systems. Even most of the UNIX operating systems is coded in 'C'. Initially 'C' programming was limited to the UNIX operating system, but as it started spreading around the world, it became commercial, and many compilers were released for cross-platform systems. Today 'C' runs under a variety of operating systems and hardware platforms. As it started evolving many different versions of the language were released. At times it became difficult for the developers to keep up with the latest version as the systems were running under the older versions. To assure that 'C' language will remain standard, American National Standards Institute (ANSI) defined a commercial standard for 'C' language in 1989. Later, it was approved by the International Standard Organization (ISO) in 1990. 'C' programming language is also called as "ANSI C'.

This makes the language easily comprehensible and enables a programmer to redesign or create a new application. C is usually used as an introductory language to introduce programing to school students because of this feature.

2. Portability: Another feature of the C language is portability. To put it simply, C programs are machine-independent which means that you can run the fraction of a code created in C on various machines with none or some machine-specific changes. Hence, it provide the functionality of using a single code on multiple systems depending on the requirement.

3. Fast: It is a well-known fact that statically types programing language are faster than dynamic ones. C is a statically types programming language, which given it an edge over other dynamic languages. Also, unlike Java and Python, which are interpreter-based, C is a complier-based program. This makes the compilations and execution of codes faster.

Another factor that makes C fast is the availability of only the essential and required features. Newer programming languages come with numerous features, which increase functionality but reduce efficiency and speed. Since C offers limited but essential features, the headache of processing these features reduces, resulting in increase speed.

4. Modularity: The concept of storing C programming language code in the form of libraries for further future uses in known as modularity. This programming language van does very little on its own most of its power if held by its libraries. C language has its own library to solve common problems like in this we can use a particular function by using a header file stored in its library.

5. Portability: Another feature of the C language is portability. To put it simply, C programs are machine-independent which means that you can run the fraction of a code created in C on various machines with none or some machine-specific changes. Hence, it provides the functionality of using a single code on multiple systems depending on the requirement.

6. Dynamic Memory Allocation: One of the significant features of C language is its support for dynamic memory management (DMA). It means that you can utilize and manage the size of the data structure in C during runtime. C also provides several predefined function to work with memory allocation. For instance, you can use the free() function to free up the allocated memory at any time. Similarly, there are other functions data structures and memory allocations.

7. Mid-Level Programming Language: Although C was initially developed to do only low-level programming, it now also supports the features and functionalities of high-level programming, making it a mid-level language. And as a mid-level programing language, it provides the best of both worlds. For instance, C allows direct manipulation of hardware, which high-level programming languages do not offer.

8. Pointers: With the use of pointers in C, you can directly interact with memory. As the name suggest, pointer point to a specific location in the memory and interact directly with it, Using the C pointer, you can operate with memory, arrays, functions, and structures.
