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.
consider int x=10;
int *y;
y=&x;
printf("value at Y is %d\n",y);
output is 10

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.
