C language was born in the mid-1960s and was developed by Dennis Ritchie of Bell Labs. Its original purpose was to write the kernel of the Unix operating system. It is inspired by programming languages ​​such as BASIC, ALGOL, and FORTRAN, and has key features of structured programming, pointers, data types, and compilers. The first C program was written in 1972 and was called "Hello, world!", demonstrating its simplicity and portability.

Where does c language start?

The origin of the C language

The birth of the C language originated in the mid-1960s, developed by Bell Laboratories Developed by computer scientist Dennis Ritchie.

Start the engine

The C language was originally developed to write the kernel of the Unix operating system. Rich wanted to create a programming language that was both efficient and portable. At the time, existing programming languages ​​were primarily targeted at specific machine architectures, and C was designed to be independent of hardware platforms.

Sources of inspiration

When designing C, Ritchie drew on several existing programming languages, including:

  • BASIC: An easy-to-use programming language for beginners
  • ALGOL: An algorithm-oriented and structured language
  • FORTRAN: A language for scientific computing

Key Features

Early versions of the C language contained some key features that would become its signature features Features:

  • Structured Programming: Supports the use of parentheses, if-else statements and loop structures
  • Pointers: Allows manipulation of memory locations Direct access
  • Data types:Defines basic data types such as int and char
  • Compiler:Translates C programs into machine code
  • Portability: Writing C programs can be easily ported to different computer platforms

First C program

In 1972, Rich wrote his first C program, a simple program called "Hello, world!" The function of this program is to print the "Hello, world!" string to the console. This program demonstrates the simplicity and portability of the C language.

Since then, the C language has continued to develop and improve, becoming a widely used programming language for developing various operating systems, applications, and embedded systems.
