Data types in C

In C language, variables are associated with data types. Each data type requires a certain amount of memory space and performs specific operations.

There are some common data types in C language:

• int - used to store integer values.

• #char - Used to store a single character.

• float - Used to store single-precision floating point numbers.

• double - Used to store double precision floating point numbers.

The following table shows the data types in C language:

##unsigned char10 to 255float41.2E-38 to 3.4E 38double82.3E-308 to 1.7E 308

Data type	Number of bytes	Range
short int	2	-32,768 to 32,767
unsigned short int	2	0 to 65,535
unsigned int	4	0 to 4,294,967,295
int	4	-2,147,483,648 to 2,147,483,647
long int	4	-2,147,483,648 to 2,147,483,647
unsigned long int	4	0 to 4,294,967,295
signed char	1	-128 to 127

The following is the syntax of data types in C language:

data_type variable_name;

This is an example of C language data type,

Example

Real-time demonstration

#include >stdio.h>
int main() {
   // datatypes
   int a = 10;
   char b = 'S';
   float c = 2.88;
   double d = 28.888;
   printf("Integer datatype : %d</p><p>",a);
   printf("Character datatype : %c</p><p>",b);
   printf("Float datatype : %f</p><p>",c);
   printf("Double Float datatype : %lf</p><p>",d);
   return 0;
}

This is the output result,

Output Result

Integer datatype : 10
Character datatype : S
Float datatype : 2.880000
Double Float datatype : 28.888000
