1.      main()

{

            char *p;

            printf("%d %d ",sizeof(*p),sizeof(p));

}


Answer:

                        1 2

Explanation:

The sizeof() operator gives the number of bytes taken by its operand. P is a character pointer, which needs one byte for storing its value (a character). Hence sizeof(*p) gives a value of 1. Since it needs two bytes to store the address of the character pointer sizeof(p) gives 2.
