C++ Program to make a bow tie

>>270886
Start by thinking about the output one line at a time, because that's what your program will be doing.
Each line will have a total of 2n + 2 characters. Since you most likely are going to use a loop for this, the amount of stars and spaces depends on what step you are on the loop. Let's say you are using i as your iterating variable. You would have 2i *s each line and the rest will be the spaces in between. That is just the total amount of characters each line is - the amount of stars each line (2n + 2 - 2i).
Since the spaces are in between the *s, each line can be summed up as: 'i' amount of stars + '2n + 2 - 2i' amount of spaces + 'i' amount of stars.
Here's some shitty pseudo code so you can do the work yourself.
loop (i = 1 to n)
{
print '*'*i + ' '*(2n + 2 - 2i) + '*'*i
}

There are way too many ways to go about it, all of the smart ones make use of a loop.
I'd personally make 4 triangles.
Here's my implementation in python

So the star-count on the left goes up to n and then start to decrease again. While printing n-(current count of printed stars spaces). And then does the same thing again in the line but prints the spaces first?
