Dear Indira P
I got u and also agree with u but first copy the below program and run then see what i am asking:-

#include<stdio.h>
#include<conio.h>
int main()
{
 	const int a=10;
 	int *ptr;
 	ptr=&a;
 	printf("\n Now the value at memory : %u  is : %d  ",&a,a); 	
 	*ptr=11;
 	printf("\n Now the value at memory : %u  is : %d  ",&a,a);
 	getch();
 	return 0 ;
}
