C Language History

The history of the programming world shaping language development process

1972 - C Language Birth

Developed by Dennis Ritchie at Bell Labs for the UNIX operating system.

1978 - K&R C Book

Kernighan and Ritchie's "The C Programming Language" book was published and the C standard was established.

1989 - ANSI C Standard

ANSI C (C89) standard was accepted and the C language was officially standardized.

1999 - C99 Standard

New features added: inline functions, variable length arrays, complex numbers.

2011 - C11 Standard

Multi-threading support, improved Unicode support and atomic operations added.

Basic Features

The powerful features and advantages of the C language

High Performance

Compiles directly to machine code with minimum overhead and efficiently uses system resources.

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

Low-Level Control

Provides pointers and direct memory access for memory management and hardware control.

int *ptr;
int num = 42;
ptr = #
printf("%d", *ptr);

Portability

Code can be written to work on different platforms. High compatibility thanks to the ANSI C standard.

#ifdef _WIN32
  // Windows kodu
#else
  // Unix/Linux kodu
#endif
