•          Assisted by Brian W. Kernighan, Ritchie wrote a book The C Programming Language (1978). Or known as K-R C / classic C.

Why Using C ?

•          Flexibility : close to low level machine language yet easy to understand.

•          Portability : used from micro computer to super computer.

•          A well known programming language in many forms of implementations: O/S, scientific application, business app., etc.

•          Supported with a large number of libraries.

     C Structure

•          C language is a structural programming language.

•          It consist of functions.

•          There is no separation between function and procedure (if you are from Pascal language background).

•          Each C program has one main function called –surprisingly– main.

•          Program will be started from the first line of the main function.

•          C language is case-sensitive.

•          Every statement should ended with a semi-colon(;) .
