Data type in C programming language

Here we divide the data into four main sections. They are as follows

1. Basic Data Type ( Ex- int, char, float, double )
2. Derived Data Type ( Ex- array, pointer, structure, union )
3. Enumeration Data Type ( Ex- enum )
4. Void Data Type ( Ex- void )
   

Basic Data Type

Signed and unsigned vocabulary can be understood in C programming language. The basic bases of basic data types are built on integers and floating data types. Basic Data Types 32-bit or 64-bit operating systems have different memory sizes. The following is the amount of memory required for a 32 bit operating system.

Data Types	Memory Size	Value range	Format Specifier
char	1 byte	−128 to 127
signed char	1 byte	−128 to 127	%c
unsigned char	1 byte	0 to 255	%c
short	2 bytes	−32,768 to 32,767
signed short	2 bytes	−32,768 to 32,767	%hi
unsigned short	2 bytes	0 to 65,535	%hu
int	2 bytes	−32,768 to 32,767
signed int	2 bytes	−32,768 to 32,767	%d. %i
unsigned int	2 bytes	0 to 65,535	%u
long int	4 bytes	-2,147,483,648 to 2,147,483,647
signed long int	4 bytes	-2,147,483,648 to 2,147,483,647	%lli, %lld
unsigned long int	4 bytes	0 to 4,294,967,295	%llu
float	4 bytes	1.2E-38 to 3.4E+38	%f
double	8 bytes	2.3E-308 to 1.7E+308	%lf
long double	10 bytes	3.4E-4932 to 1.1E+4932	%Lf

 

 

 

 

 

 

 

 

 

int

Integers can consist of zero, positive and negative values. But should not be decimal. You can use this for the integer variable.

 Ex. A student ID number, customer age

int student_ID, intcustomer_age;

Float and Double

Uses float and double to enter any real number. You can think of almost any mathematical number as a real number. That means you can add whole numbers, logical numbers, irrational numbers to this. But we cannot add imaginary numbers to this.

 Ex. - 0, 1, 2, 3, 4,  3/4, 0.125, 0.333

The main difference between Claude and Double is their size. That is, double  includes 8 bytes and float has 4 bytes. Larger real numbers can be used for doubles and smaller real numbers can be added for floats. There are a maximum of six decimal places that can be entered for float.

float salary, iteam_price;
double speed_of_light;

char

The char keyword is used to enter character type variables.

char test = 'K';
