I need help in making a hollow parallelogram

[kamilhassaan]

I want this;

   **********
  *        *
 *        *
**********

So far, I got this;

#include <iostream>
using namespace std;
int main()
{
	int lines = 0 , row = 0;
	cin >> lines;
	
	for(int top_border=0 ; top_border<lines*3 ; top_border++)
	{
		cout << "*";
	}	
	cout << endl;
	
	for(int side_border=0 ; side_border<lines-1 ; side_border++)
	{
		cout << "*";
		for(int hollow=0 ; hollow<lines*3-2 ; hollow++)
		{
			cout << " ";
		}
		cout << "*" << endl;
	}
	
	for(int low_border=0 ; low_border<lines*3 ; low_border++)
	{
		cout << "*";
	}
}

How can I add space space before the left border?

#include <iostream>
using namespace std;
int main()
{
	int lines = 0;
	cin >> lines;
	
	for(int row=1 ; row<=lines ; row++)
	{
		for(int space=0 ; space<lines-row; space++)
		{
			cout << " ";
		}
		for(int star=0 ; star<lines*3 ; star++)
		{
			cout << "*";
		}
		cout << endl;
	}
}

Is there any way i can utilize this code for the space before the left border?
