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.

#include <stdio.h>

int main() {
   // datatypes
   int a = 10;
   char b = 'S';
   float c = 2.88;
   double d = 28.888;
   printf("Integer datatype : %d\n",a);
   printf("Character datatype : %c\n",b);
   printf("Float datatype : %f\n",c);
   printf("Double Float datatype : %lf\n",d);
   return 0;
