History of C

C is a general-purpose, high-level language that was originally developed by Dennis M. Ritchie to develop the UNIX operating system at Bell Labs. C was originally first implemented on the DEC PDP-11 computer in 1972.
In 1978, Brian Kernighan and Dennis Ritchie produced the first publicly available description of C, now known as the K&R standard.
The UNIX operating system, the C compiler, and essentially all UNIX application programs have been written in C. C has now become a widely used professional language for various reasons −
  • 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

Facts about C

  • C was invented to write an operating system called UNIX.
  • C is a successor of B language which was introduced around the early 1970s.
  • The language was formalized in 1988 by the American National Standard Institute (ANSI).
  • The UNIX OS was totally written in C.
  • Today C is the most widely used and popular System Programming Language.
  • Most of the state-of-the-art software have been implemented using C.
  • Today's most popular Linux OS and RDBMS MySQL have been written in C.

Why use C?

C was initially used for system development work, particularly the programs that make-up the operating system. C was adopted as a system development language because it produces code that runs nearly as fast as the code written in assembly language. Some examples of the use of C might be −
  1. Operating Systems
  2. Language Compilers
  3. Assemblers
  4. Text Editors
  5. Print Spoolers
  6. Network Drivers
  7. Modern Programs
  8. Databases
  9. Language Interpreters
  10. Utilities

Features of C Language

Image
Features of C Language C is the widely used language. It provides many  features that are given below. Simple Machine Independent or Portable Mid-level programming language structured programming language Rich Library Memory Management Fast Speed Pointers Recursion Extensible 1) Simple C is a simple language in the sense that it provides a  structured approach  (to break the problem into parts),  the rich set of library functions ,  data types , etc. 2) Machine Independent or Portable Unlike assembly language, c programs  can be executed on different machines  with some machine specific changes. Therefore, C is a machine independent language. 3) Mid-level programming language Although, C is  intended to do low-level programming . It is used to develop system applications such as kernel, driver, etc. It  also supports the features of a high-level language . That is why it is known as mid-level language. 4) S...

C can also be defined has

C can be defined by the following ways: Mother language System programming language Procedure-oriented programming language Structured programming language Mid-level programming language 1) C as a mother language C language is considered as the mother language of all the modern programming languages because  most of the compilers, JVMs, Kernels, etc. are written in C language , and most of the programming languages follow C syntax, for example, C++, Java, C#, etc. It provides the core concepts like the array, strings, functions, file handling, etc. that are being used in many languages like C++, Java, C#, etc. 2) C as a system programming language A system programming language is used to create system software. C language is a system programming language because it  can be used to do low-level programming (for example driver and kernel) . It is generally used to create hardware devices, OS, drivers, kernels, etc. For example, Linux kernel...

if else control statements

C if else Statement The if-else statement in C is used to perform the operations based on some specific condition. The operations specified in if block are executed if and only if the given condition is true. There are the following variants of if statement in C language. If statement If-else statement If else-if ladder Nested if If Statement The if statement is used to check some given condition and perform some operations depending upon the correctness of that condition. It is mostly used in the scenario where we need to perform the different operations for the different conditions. The syntax of the if statement is given below. if (expression){   //code to be executed    }   Flowchart of if statement in C Let's see a simple example of C language if statement. #include<stdio.h>      int  main(){     int  number=0;   ...
