3. HEADER FILE
• A header file is a file with extension .h which contains C function declarations .
• There are two types of header files :
Files that the programmer writes and
Files that comes with a compiler.
• For Example:
stdio.h header file contains standard Input and Output functions.
string.h header file contains string handling functions.

int main()
{
-----Statements----
// comments after double slash
}

8. Comments in c
• A comment is a programmer-readable explanation;
• They are added with the purpose of making the source code easier for humans to understand,
and are generally ignored by compilers and interpreters.
• Example-
• Single line comment-
//(double slash);
Multiline comment-
/*---------
------*/
• This can span over to multiple line;

10. variables
• Variables are data that will keep on changing. A variable is nothing but a name given to a
storage area that our programs can manipulate.
• Declaration
<<Data type>> <<variable name>>;
int a;
• Definition
<<varname>>=<<value>>;
a=10;
• Usage
a=a+1; //increments the value of a by 1

11. Variable names-Rules

12. Constants
• Constants refer to fixed values that the program may not alter during its
execution. These fixed values are also called literals.
• Given below is the form to use #define preprocessor to define a
• const
• #define identifier value
