 #include <stdio.h>
  
  int main ( ) {

	void setTo5 (int *p) /* takes in a pointer */
	{
		*p = *p - 22; /* the value the pointer points to assigned to that value - 22 */
	}

      int n = 27;
      setTo5 (&n); /* takes in the address of n */
      printf ("n = %d\n", n);  /* should print n = 5 */
      return 0;
  
  	
  }
