This is the first video of C language series,
this video is very useful and helpful for you specially, for students
in this video we have learned,

Basic Structure of C Program:-
"The format or way according to which a computer program is written is called the structure of the program".
The program structure of different programming languages is different. C is a structured programming language.
It provides a well defined way of writing programs.


The whole program is controlled within main ( ) along with left brace denoted by “{” and right braces denoted by “}”.
If you need to declare local variables and executable program structures are enclosed within open brace “{” and “}”
and close brace this is called, body of the main function.
The main ( ) function can be preceded by documentation, preprocessor statements and global declarations.

Documentation section:
The documentation section consist of a set of comment lines giving the name of the program,
the another name and other details, which the programmer would like to use later.

Single line comments:
we can write single line comment with the double forward slash
for exaple:
// this is my first program

Multiple line comments:
The characters or words or anything which are given between this “/*” and this sign “*/”, won’t be considered by C compiler for
compilation process.These will be ignored by C compiler during compilation.

Preprocessor Statements or link section:
The preprocessor statement begin with # symbol and are also called the preprocessor directive.
These statements instruct the compiler to include C preprocessors such as header files and
symbolic constants before compiling the C program.

Definition Section:
All the symbolic constants are written in definition section.
Macros are known as symbolic constants.

Global Declarations:
The variables are declared before the main ( ) function as well as user defined functions are called global variables.
These global variables can be accessed by all the user defined functions including main ( ) function.

The main ( ) function:
Each and Every C program should contain only one main ( ).
The C program execution starts with main ( ) function.
No C program is executed without the main function.
The main ( ) function should be written in small (lowercase) letters and it should not be terminated by semicolon.
