Introduction to C Language ( RunC 0 )

C Language

A First step in modern programming languages.

C Programming Language is developed by Dennis M and Ritchie at Bell Labs. Which is first publicly available in 1978.

C is very basic language

• Easy to learn
• Structured language
• It produces efficient programs
• It can handle low-level activities
• It can be compiled on a variety of computer platforms

Programming Language :

Every Programming Language will have set of predefined Keywords and Identifiers.

Keyword which is very new for you... am i right ?

Keywords are the reserved words used in programming. Each keywords has fixed meaning and that cannot be changed by user.

Keywords are defined by the Creators of that programming language.

Eg : int i;

Here "int" is a Keyword (Don't get confuse we will discuss it later)

Eg : Word "Good" from english... This will give same meaning in any sentense.

In the same way Keyword will give same logic in any program written by the Programmer (It's you, You are C Programmer).

Identifier ? (what I have to identify here ? oh no)

In C programming, identifiers are names given to C entities, such as variables, functions, structures etc.

give unique name to C entities to identify it during the execution of program.

Eg : int i;

Here "i" is a Identifier (Don't get confuse we will discuss it later)

Identifier is used to identify the Variables names declared by the Programmer.

Simply the name which given to the variable in your program snippet.

Now you Know What is a Keyword and What is a Identifier.

Note :If you want to learn Programming Lanaguage you should know how to compare your daily life with the programs so it makes easy to understand.
