A.Because you can get value stored at any address only through *.& is used to retrieve the address value.!

It is also called as 'Indirection operator' and it is used to get the value stored at pointer add.

For example;
consider int x=10;
int *y;
y=&x;
printf("value at Y is %d\n",y);
output is 10
bescause 10 is stored at address say 100(which named as 'x') and again we are declaring 'y' as pointer variable which holds address of another variable(here y holds adress of 'x')which is dereferenced using "&" opearator.

It is a very good platform to learn more programming.

By using * (pointer) symbol only we can found the answer.
Also pointer main work is to store the address of another variable.

@Govardhana Kj :
U r correct but output should be 100(address of x), coz u r printing y not *y . :) :)
printf("value at Y is %d\n",y);

No apurva is right. Output is 10 if we declare *y.

What if give int *y;
y=&x;
printf("%d",&y);

@Aabir :
int x=20;
int *y=&x;
y=address of x
*y=data of x;
&y == y(same)

No. Actually
y gives address of x
*y gives data of x
&y gives the address of y. The memory which contains the address of x.

For example;
consider int x=10;
int *y;
y=&x;
printf("value at Y is %d\n",y);
output is 10
it is wrong if you r printing *y only get value 10
otherwise it returns address

& is used to specify the address... eg &a specifies the address...
* and -> can be used to get the values of the pointer....

No error program:
float y=3,*i;
i=&y;
printf("value of y is %f",y);
printf("value of i is %f",i);
printf("value of y is %f",*i);
But we know address are only integers.
Then how it is assign floating point?

A. Yeah * is a symbol of pointer and we already know that pointer stores the address of the another variable.
