Data Types In C Programming

         C Programming supports different types of data types. The different data types require different memory for storage. There four basic data types int, char, float and double.
           The 'int' is used to store the integer value, 'char' is used to store any character, 'float' is used to store the floating value and double is used to storing the double value.
         Different data types also have a different range. Ranges may vary from compiler to compiler. The below specifiers on 32-bit GCC compiler.

Basic Data Types	Data Types withe type qualifiers	Size(bytes)	Range
char	signed char	1	-128 to +127
	unsigned char	1	0 to 255
int	int or signed int	2	-32768 to 32767
	unsigned int	2	0 to 65535
	short int or signed short int	1	-128 to 127
	unsigned short int	1	0 to 255
	long int or signed long int	4	-2147483648 to 2147483647
	unsigned long int	4	0 to 4294967295
float	float	4	3.4E-38 to 3.4E+38
double	double	8	1.7E-308 to 1.7E+308
	long double	10	3.4E-4932 to 3.4E+4932

              The size of the operator can be used to fin the size of variables. The following program can be used to find the size of the variable

#include <stdio.h>
main()
{
        printf("sizeof(char)=%u\n",sizeof(char));
        printf("sizeof(short)=%u\n",sizeof(short));
        printf("sizeof(int)=%u\n",sizeof(int));
        printf("sizeof(long)=%u\n",sizeof(long));
        printf("sizeof(float)=%u\n",sizeof(float));
        printf("sizeof(double)=%u\n",sizeof(double));
        printf("sizeof(long double)=%u\n",sizeof(long double));
}

The output is
