     “C” Tokens

When we  a paragraph in any language the individual word and punctuation mark are called tokens

In c language tokens can be defined as small units keywords identifiers. Constants.

Example token

Keyword ‘do’ while,if,etc

Identifier

Constants

Strings

Special symbol

Operation +,-,\,* etc

Constants:

Constants is an entity which doesn’t changes during executions of program

Types of constant

A integer constants.

-1234,-1254

B floating point constants

12.1, 314, etc

Variable in “C”

Variable in entity which changes during execution program

DATA Types

Int:

‘int’ use to store integer value only no decimal points are allowed its takes 2 bytes of memory

Range: -32768 to 32767

Char

‘Char’

Char use to store single character only it occupies 1 byte of memory

Range: -128 to 127

ACSII(American standard information interchange)

It’s a one byte code ACSII number represents on unique character.

ACSII number of a character is use to represents a character in binary.

Float

“float” use to store float pointer it occupies 4 byte of memory

Rage: 3.4e-38 to 3.4e38

More types of data

Data types is mainly used to allocate the memory when we declare variable of any valid data type then computer allocates fixed size of memory.

To modify default behaious of data type in memory allocation “C” provide following type modifiers keywords

“Short”

Its default modifier for “int” and “float” data type.
