Odd Magic Square NxN C++ code

The blogger interface is stupid it keeps formatting my input so I am attaching the whole cpp file. Get the C++ Code. Ofcourse rename the file remove the .zip extension

Magic Squares Algorithm & C++ implementation

Hi all,
This time around its something a bit tricky generating an odd magic square. Details are given everywhere. The wiki entry is sufficient, check it out http://en.wikipedia.org/wiki/Magic_square.

I base on the same logic which is commonly followed the one up one right stepping strategy. Here is the pseudocode,

 
//n is the dimension of magic square for a 3*3 square n=3; 

int magic[n][n]={0};

curRow=0, curCol=1;

oldRow=0, oldCol=0;

count =0;

for(i=1;i<=n;i++) 

{    

   for(j=1;j<=n;j++)      

   {       

      //See if we are into an empty cell       

      if( magic[curRow][curCol]==0 )       

      {           

          magic[curRow][curCol] = ++count;       

      }     

      else 

      {        
  
         //Move down from the previous row but keep the same column           

         magic[(oldRow+1)%n][oldCol] = ++count;           

         curRow = (oldRow+1)%n;           

         curCol = oldCol;       

      }        

      //Store the last row and column index        

      oldRow=curRow;       

      oldCol=curCol;        

      

      //Move one up and one right       

      curRow=(curRow-1)%n;       

      curCol=(curCol+1)%n;              

     

      //Wrap around the size       

      if(curRow<0) 

         curRow =n-1;

   }

}
