Making these horizontal lines vertical

igotabuginmyeye (12)
Hey all! Been racking my brain working on getting the horizontal lines within the diamond trying to make them vertical.

I'm guessing that I need to take the if-else pair (line 32) outside of the brackets and perhaps upwards beneath the initial for loop (line 19) but anything i try results in disaster!

#include <iostream>

using namespace std;

int main()
{
   int n;
   int j;
   char border;
   char fill;

   cout << "Enter Diamond radius: ";
   cin >> n;
   cout << "Enter border character: ";
   cin >> border;
   cout << "Enter a fill character: ";
   cin >> fill;
   
   for (int i = (1-n); i < n; i++)
	{
		for (j = 0; j < abs(i); j++)
		{ //outer spaces
			cout << " ";
		}	

      cout << border;

		if(abs(i) != (n-1)) //if not the first or last row, print a second "A"
			{
				for (int k = 1; k < 2*((n-1)-abs(i)); k++)
					{ //inner spaces
						if (j % 2 == 0) //if on an even row output spaces
							{
								cout << " ";
							}
						else //if on an odd row output the fill character
							{
								cout << fill;
							}
			
					}
						cout << border;
			}

		cout << endl;
   }
}


Thanks guys!

I think you need to include this line...
# include <cmath>

To get them vertical?

All works fine without it. Why is it necessary?

On line 32 replace j with (k+i)
