Trouble printing an arrow

Feb 28, 2014 at 11:44pm
Here I've tried to separate the arrow by pritning the top part then the longest and last the opposite of the top piece. I worked my way form the inside out with the for loops but they don't seem to be coordinating correctly. Any hints so that this is printed?

What I want to print:
      *
      ***
***********
      ***
      *

  void printArrow(int n)
{

    for(int i = 0; i < n + 1; i++)
    {
        for(int j = 1; j < n; j += 2)
        {
            for(int k = 0;k < ((4*n+3)/2); k++)
            {
                cout << ' ';                  //sets the spaces

            }
            if(j == 1)
                cout << '*';            //prints the first start alone
            else
            {
                for(int h = 0; h <= j; h++)     //prints the rest
                    cout << '*';
            }
            
            cout << endl;
        }
    }
    for(int k = n + 1; k < (4 * n + 3);k++)   //middle/longest line in arrow
    {
        if(k == (4 * n + 3) - 1)                //prints the last star
            cout << '*';
        else                                //prints the rest
            cout << '*';
    }
    for(int x = n + 1; x == 0; x--)
    {
        for(int j = 0; j < n; j -= 2)
        {
            if(j == 0)
                cout << '*';            //prints the last start alone
            else
            {
                for(int h = 0; h <= j; h++)     //prints the rest
                    cout << '*';
            }
            cout << setw((n+1)*2) << endl;      //sets the spaces
            
            cout << endl;
        }
    }

Why don't you explain what you want the arrow to look like for 2 or 3 different given inputs?

For instance 6 and 13? What should the arrow look like for those two numbers?

oh lord, ill never understand the silly exercises they make you do to teach you loops.
