Introduction

C programming language is a procedural and general-purpose programming language created by Dennis Ritchie at the Bell Laboratories in 1972.

The C programming language offers various features and functionalities to the programmers. It includes low-level memory access, simple syntax, and a clean style. It makes the C programming language suitable for system programming like compiler development and operating system development.

C files have the file extension .c
There are other file extensions in C like the header files, but we would talk about them later.

Requirement

There are two(2) basic requirements to for coding in C:

  • A text editor to write C code. Examples
    • Vim
    • Notepad etc.
  • A compiler to translate the C code into a language that the computer will understand. Example: GCC

You could also use an IDE, which most times come with a text editor and compiler

Setup

There is not much to setup, once you have your test editor and Compiler

To check if your compiler is installed, run the following command in your terminal

gcc --version

You should see the version of the compiler you are using

Coding Style (Betty)

In this tutorial, we are going to be using the Betty Coding Style. To read more about the rules of this style, checkout Betty Repository.

And also a Video on how to install Betty in your Linux Based Computer here.

KeyWords

There are 32 keywords in the C programming language.

Keywords are reserved words in the language which has its own meaning to the compiler and cannot be used as a user-defined identifier

Keywords in C are as follows

KeyWords                                                                                                                                                      
auto break case char
const continue default do
double else enum extern
float for goto if
int long register return
short signed sizeof static
struct switch typedef union
unsigned void volatile while

You can also checkout my repo showing examples for each keyword here

Enough of the talk. In the Next Section, we are going to write some code.
