Origin of C Programming Language

History and Development

The C programming language was created by Dennis Ritchie at Bell Laboratories between 1972 and 1973. It was developed as a successor to the B programming language and was originally designed for the Unix operating system.

  • Founder : Dennis Ritchie (September 9, 1941 – October 12, 2011)
  • Year : 1972-1973
  • Place : Bell Laboratories, USA
  • Purpose : Initially developed for Unix system development

  • Dennis Ritchie - Father of C
Advantages of C
  • Middle-level language with low-level capabilities
  • Fast and efficient execution
  • Portable across different platforms
  • Rich set of built-in operators
  • Extensive library support
  • Foundation for many other languages
Disadvantages of C
  • No runtime checking
  • Lack of object-oriented features
  • No direct support for multithreading
  • Manual memory management
  • No string handling built-in

Key Concepts in C
  • Memory Management : Understanding stack vs heap, malloc, free
  • Pointer Arithmetic : Address manipulation and memory access
  • Preprocessor Directives : #include, #define, macros
  • Storage Classes : auto, static, extern, register
  • Bit Manipulation : Bitwise operators and operations
  • Standard Library : stdio.h, stdlib.h, string.h, math.h
First C Program - Hello World

The "Hello, World!" program is a simple C program that displays the message "Hello, World!" on the screen. It's often used as a starting point for learning a new programming language. Here's the code:

   #include <stdio.h>
  int main() {
  printf("Hello, World!\n");
  return 0;
  }
