# C Programming – Introduction
Before we can begin to write serious programs in C, it would be interesting to find out what really is C, how it came into existence and how does it compare with other computer languages. In this article we would briefly outline these issues.
C is a programming language developed at AT & T’s Bell Laboratories of USA in 1972. It was designed and written by a man named Dennis Ritchie.
C is a powerful general-purpose programming language. It is fast, portable and available in all platforms. Possibly why C seems so popular is because it is reliable, simple and easy to use.
If you are new to programming, C is a good choice to start your programming journey.
This is a comprehensive guide on how to get started in C programming language, why you should learn it and how you can learn it.
# What is C (Programming Language)? – The Basics
Before getting started with C programming, lets get familiarized with the language first.
C is a general-purpose programming language used for wide range of applications from Operating systems like Windows and iOS to software that is used for creating 3D movies.
C programming is highly efficient. That’s the main reason why it’s very popular despite being more than 40 years old.
Standard C programs are portable. The source code written in one system works in another operating system without any change.
As mentioned, it’s a good language to start learning programming. If you know C programming, you will not just understand how your program works, but will also be able to create a mental picture on how a computer works.
C is a popular programming language which is commonly used by scientists and engineers to write programs for any specific application. C is also a widely accepted programming language in the software industries.
# Analogy between learning English language and learning C language
Communicating with a computer involves speaking the language the computer understands, which immediately rules out English as
the language of communication with computer. However, there is a close analogy between learning English language and learning C language.
The classical method of learning English is to first learn the alphabets used in the language, then learn to combine these alphabets to form words, which in turn are combined to form sentences and sentences are combined to form paragraphs.
Learning C is similar and easier. Instead of straight-away learning how to write programs, we must first know what alphabets,
numbers and special symbols are used in C, then how using them constants, variables and keywords are constructed, and finally how are these combined to form an instruction. A group of instructions would be combined later on to form a program.
