[Dev-C++] Can anyone figure this one out?

[<Tre...@ao...>]

To me, this code looks fine. When I execute the program it should give me a 
reverse of the first pattern when I choose pattern2, but it gives me the same 
output as pattern1.  
#include<iostream>


using namespace std;

//*****function prototypes
void getPattern1(int &, int &);
void getPattern2(int &, int &);

   
int main()

{
   int pattern = 0;
   int lines = 0;
   int stars = 0;

   cout << "Enter 1 for pattern1 or 2 for pattern2: " << endl;
   cin >> pattern;

   if (pattern == 1)
   {
        getPattern1(lines, stars);
   }
   else
   {
        getPattern1(lines, stars);
   }
return 0;
}


//*****functions*****
void getPattern1(int &lines, int &stars)
{       
      lines = 9;
      while (lines > 0)
      {
        stars = lines;
        while (stars > 0)
        {
            cout << '*';
            stars--;
        }
        cout << '\n';
        lines--;
      }
}
void getPattern2(int &lines, int &stars)
{

      lines = 1;
      while (lines < 10)
      {
        stars = lines;
        while (stars < 10)
        {
            cout << '*';
            stars++;
        }
        cout << '\n';
        lines++;
      }
       
 }
