Basic Inverse Pyramid Program!

[billybob1]

Can anyone please explain how i would manipulate the following program to reflect an inverse pyramid and how to also get an upside down pyramid?

#include <iostream>
#include <stdio.h>
using namespace std;

int main()
{
	int i, j, k, n;
	cout<<("Enter number of rows for pyramid: ");
	cin>> n;

	cout<<("\n");

	for (i = 1; i <= n; i++)
	{
		for (j = 0; j < (n - i); j++)
			cout<<(" ");
		for (j = 1; j <= i; j++)
			cout<<("*");
		for (k = 1; k < i; k++)
			cout<<("*");
		cout<<("\n");
	}
	cout<<("\n\n");

	system("PAUSE");

	return 0;
}
