Pointers are an extremely powerful programming tool.   help improve your program's efficiency, and even allow you to handle unlimited amounts of data.
For ex.
#include <stdio.h>
  int main()
{
     int x;
     int *p; /* A pointer to an integer
     p = &x;
     scanf( "%d", &x );
     printf( "%d\n", *p );
 getchar();
 }
