PRIMARY DATA TYPES

DATA TYPES IS VERY IMPORTANT PART OF C LANGUAGE OR ANY OTHER LANGUAGE .
WITHOUT USING DATA TYPE YOU CANNOT UNDERSTAND THE TYPE OF ANY GIVEN DATA . DATA TYPE HELPS TO UNDERSTAND THE DATA WHICH YOU ARE INPUT FROM THE KEYBOARD , IT IS NUMERIC TYPE , CHARACTER TYPE OR DECIMAL TYPE .

*DATA TYPES:-

DIFFERENT TYPES OF DATA ARE COULD BE USED IN ANY LANGUAGE , IS CALLED ITS DATA TYPE .

for example:- name will always be alphabetic data , age is numeric data type , etc .

HERE WE SHALL DISCUSS ABOUT VARIOUS TYPES OF DATA TYPES WHICH ARE USING IN C LANGUAGE .

IN THIS POST WE SHALL DISCUSS ABOUT ONLY PRIMARY DATA TYPES .

1.) PRIMARY or PRIMITIVE DATA TYPES:-

THESE ARE FUNDAMENTAL DATA TYPE IN C INTEGER(int) , FLOAT(float) ,CHARACTER(ch) , DOUBLE(double) AND VOID(void). .

i.) INTEGER TYPE:-

INTEGER DATA TYPE ARE USED TO STORE WHOLE NUMBERS . INTEGER STORES 2 BYTE AND ITS RANGE IS FROM -32.768 TO 32.767 . INTEGER MEMORY STORY DEPENDS ON BIT OF THE COMPUTER , IT IS 16 BIT ,32 BIT OR 64 BIT .

*The following table provides the details of standard integer types with their storage sizes and value ranges −

ii.) CHARACTER TYPE:-

CHARACTER TYPE ARE USED TO STORE ALPHABETIC DATA .
CHARACTER STORES 1 BYTE IN COMPUTER MEMORY LOCATION AND ITS RANGE IS FROM -128 TO 127 .

*The Following table provides the detail of standard character types with their storage , sizes and value ranges .

iii.) FLOAT DATA TYPE:-

FLOAT DATA TYPE ARE USED TO STORE THE DECIMAL VALUES LIKE 3.8 ,0.05 ETC . FLOAT STORES 4 BYTE AND ITS RANGE IS FROM -3.4e382 TO 3.4e382 .

iv.) DOUBLE DATA TYPE:-

THE DOUBLE TYPE IS SAME AS FLOAT TYPE ONLY , WITH ROUGHLY TWICE THE PRECISION . DOUBLE DATA TYPE STORES 8 BYTE IN MEMORY LOCATION AND ITS RANGE IS FROM -1.7e308 TO 1.7e308 .
