Introduction to C language | 1st session

Today is the first session of the c language so i will tell all the basics of c & other  .

What is C & its uses ?

• C is called a higher level compiler language which can be used for general purpose programming like for writing small  programs or to write complex application .
• The C language has been equipped with features that allow programs to be organized in an easy and logical way.
• C allows meaningful variable names and meaningful function names to be used in programs without any loss of efficiency and it gives a complete freedom of style .
• C has a set of very flexible loop structure & clean ways of making decisions & this provide an excellent basis of controlling the flow of program .
• C allows things which are disallowed in other languages: this is no defect but a very powerful freedom .
• C tries to make the best of a computer by linking as closely as possible to the local environment .

Now i will tell you some characteristics of C :.

Characteristics of C  :

• Small size
• Extensive use of function calls
• Loose typing -- unlike PASCAL
• Structured language
• Low level (BitWise) programming readily available
• Pointer implementation - extensive use of pointers for memory, array, structures and functions .
• It has high-level constructs.
• It can handle low-level activities.
• It produces efficient programs.
• It can be compiled on a variety of computers.

Basic C Program structure :

• Preprocessor Commands
• Type definitions
• Function prototypes -- declare function types and variables passed to function.
• Variables
• Functions

In the session  i will teach you about common functions, commands & also to write small programs so  be updated ...
& any doubt then i'm always ready to answer ;)
