C PROGRAMMING FAQs
What is C Programming Language?
C is a structured Oriented Programming language that is used for the development of software and used to writing various applications. It is a middle-level language that has both low-level and high-level features. It is considered the base of all programming languages It is the most popular and simplest programming language that is very flexible to use.
The History of C Programming Language
C Programming language was created in the 1970s by Dennis Ritchie. It is considered the successor of the B language. C was originally developed to write an Operating System called UNIX. The UNIX Operating System development started in the year 1969 and its code was rewritten in C in the year 1972.
What is C language used for?
It can be used to develop software like operating systems, databases, compilers, and so on. This language is machine Independent and extensively used to write various applications, Operating Systems, and other complex programs like Oracle Database, Git, Python interpreter, and more.
Why you should consider learning C?
C is an old language but still it is the most popular. It owes its popularity to the rise and success of UNIX. For beginners, it is one of the best and most suitable programming languages for learning. C is the base of all the programming languages that’s why those who know ‘C’ very well, can grasp all other programming languages very fastly. To be able to learn higher-level languages like C++ and Java you must have knowledge of C.
Key advantages of learning C language…
Easy to learn
Structured Language
It produces efficient programs
It can handle low-level activities
It can be compiled on a variety of computer platforms
C is Powerful and Flexible
C is highly flexible and machine Independent. It is universal and programs written in it can be compiled and run across many platforms, architectures and a variety of machines without losing any performance.
This makes C a great choice for creating systems and programs where performance really matters.
Facts about C Language
