Question: What are the advantages of pointers,give me programs containing variables and pointer variables?

Answer: POINTER IS JUST LIKE A VARIABLE WHICH HOLDS THE ADDRES OF ANOTHER VARIABLE.POINTER IS DENOTED BY ASTERIK(*) SIGN.POINTER HAVE VERY IMPORTANT USE IN 'C' LANGUAGE.
/*PROGRAM DEMONSTRATES THE CONCEPT OF POINTER */
#include <stdio .h>
#include<conio.h>
void main()
{
int a=10;
int *m;//pointer type declaration
clrscr();
printf("the value of a==%d",a);
printf("the value of a==%d",*m);
printf("the adres of a==%u",&a);
printf("the adres of a==%u",m);
getch();
