Below are the some important special operators in c language

Operators	Description
sizeof (var_name)	This operator returns the size of the variables in memory.
&	This returns the memory address of operator variables.
*	This operator returns the pointer of the variable.

EXAMPLE :-

// Special operators in C.

#include <stdio.h>

int main()

{

int p;

float q;

double r;

char s;

printf("Size of int=%lu bytes\n",sizeof(p));

printf("Size of float=%lu bytes\n",sizeof(q));

printf("Size of double=%lu bytes\n",sizeof(r));

printf("Size of char=%lu byte\n",sizeof(s));

return 0;

}

OUTPUT

Size of int = 4 bytes Size of float = 4 bytes Size of double = 8 bytes Size of char = 1 byte
