Data Types in C

Variables in C are associated with data type. Each data type requires an amount of memory and performs specific operations.

There are some common data types in C −

• int − Used to store an integer value.

• char − Used to store a single character.

• float − Used to store decimal numbers with single precision.

• double − Used to store decimal numbers with double precision.

The following table displays data types in C language −

Here is the syntax of datatypes in C language,

data_type variable_name;

Here is an example of datatypes in C language,

Example

 Live Demo

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

Here is the output,

Output

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