POINTERS
========
a pointer is a variable whose value points to another variable's address.
in order to have a pointer actually point to another variable it is necessary
to have the memory address of that variable. to get the memory address of the variable,
put the & sign in front of the variable name. this is called the reference operator,
because it returns the memory address.

#include<iostream.h>
int main()
{
	int x; //a normal integer
	int *pointer; //a pointer to an integer
	pointer = &x; //READ IT, "pointer equals the address of x"
	cin >> x; //reads in x
	cout << *pointer; //NOTE the use of the * to outputthe actual number stored in x
	return 0;
}

/* notice that; the pointer is initialized to pointto a specific memory address before
it is used. if this was not the case, it could be pointing to any thing. 

  * the delete operator frees_up the memory allocated through new. to do so, the syntax 
  is as follows:
				delete pointer;
----------------
#include<iostream.h>
int main()
{
	int students;
	cout <<"Enter the number of students :";
	cin >> students;
	cout <<"\nNumber of students :" << students;
	cout << "\n\n";
	return 0;
}
-----------------
#include<iostream.h>
int main()
{
	int students;
	int *ptrstudents;
	ptrstudents = &students;
	cout <<"Enter the number of students :";
	cin >> students;
	cout <<"\nNumber of students :" << students
		<<"\nThat is: " << *ptrstudents << " students." ;
	cout << "\n\n";
	return 0;
}

on test..
*write an array of integers that creates an array of 10 integers
*int r=what(2,x);
 cout << what(x,r) << endl;
