#include <stdio.h>

void main()
{
	// declare the variables:
	int nNumber;
	int *pPointer;

	// now, give a value to them:
	nNumber = 15;
	pPointer = &nNumber;

	// print out the value of nNumber:
	printf("nNumber is equal to :  %d", nNumber);

	// now, alter nNumbe through pPointer:
	*pPointer = 25;

	// prove that nNumber has changed as a result of the above by printing its value again:
	printf("nNumber is equal to : %d\n", nNumber);
