Introduction to C Programming

Introduction to Programming.

To solve a computing problem, its solution must be specified in terms of the sequence of computational steps such that they are effectively solved by a human agent or by a digital computer.

Introduction to Programming Language.

1. The specification of the sequence of computational steps in a particular programming language is termed as a program

2. The task of developing programs is called programming

3. The person engaged in programming activity is called programmer

Introduction to C Programming

C is a general-purpose computer programming language developed in 1972 by Dennis Ritchie at the Bell Telephone Laboratories for use with the Unix operating system. C is a structured programming language, which means that it allows you to develop programs using well-defined control structures (you will learn about control structures in the articles to come), and provides modularity (breaking the task into multiple subtasks that are simple enough to understand and to reuse). C is often called a middle-level language because it combines the best elements of low-level or machine language with high-level languages.  

Where is C useful? 

C’s ability to communicate directly with hardware makes it a powerful choice for system programmers. In fact, popular operating systems such as Unix and Linux are written entirely in C. Additionally, even compilers and interpreters for other languages such as FORTRAN, Pascal, and BASIC are written in C. However, C’s scope is not just limited to developing system programs. It is also used to develop any kind of application, including complex business ones. The following is a partial list of areas where C language is used: 

1. Embedded Systems

2. Systems Programming 

3. Artificial Intelligence 

4. Industrial Automation

5. Computer Graphics

6. Space Research
