Data Types In C: Size, Range and Usage.


DATA TYPES IN ‘c’

Data types are keywords which specify the type of data which is used in the programs of C language. Different data types have different storage capacities and different range of data.

There are mainly two main categories of data types.



PRE-DEFINED DATA TYPES/PRIMARY DATA TYPES

INTEGER TYPE DATA TYPES


Integer type data type is used to store a whole number or integer number


TypeSize(bytes)Range
int or signed int2-32,768 to 32767
unsigned int20 to 65535
short int or signed short int1-128 to 127
unsigned short int10 to 255
long int or signed long int4-2,147,483,648 to 2,147,483,647
unsigned long int40 to 4,294,967,295

FLOAT TYPE DATA TYPE

Float type data types are used to store a real number.

TypeSize(bytes)Range
Float43.4E-38 to 3.4E+38
double81.7E-308 to 1.7E+308
long double103.4E-4932 to 1.1E+4932

CHARACTER DATA TYPE

Character type data type is used to store Character type value

TypeSize(bytes)Range
char or signed char1-128 to 127

These are the keywords in C. auto double int struct break else long switch case enum register typedef char extern return union const float short unsigned continue for signed void default goto sizeof volatile do if static while The Keywords in Red are the data types they are used to define the data type of a variable. Example: int i; float f; char ch; long l; The Usage of these keywords will be covered as they arrive ...

Variable: Declaration, initialization and Usage

Variable Variables are the names given to some memory location where a value is stored; the variable is corresponding to the data or value input in it. RULES FOR DEFINING A VARIABLE / VARIABLE NAME: · A Variable name should not have name of any KEYWORDS in C. · A Variable name can be alphanumeric but should start with an Alphabet. · A Variable name should not consist of any special symbol other than “_” Underscore Symbol.  · A Variable should be defined before using it. VARIABLE DECLARATION: In this step, the variables are declared, this steps always occurs before using the variables. FORMAT:   EXAMPLE: VARIABLE INITIALIZATION: Providing a Value to any variable is called initialization. INITIALIZATION AT THE TIME OF DECLARATION: The variable can be given its value at the time of declaration. USAGE OF VARIABLE: Here is the example, to show how a vari...
