This code is a work in progress, but I'm trying to write a program that takes inputs for the coordinates and dimensions of both a line and a circle and prints them out in the terminal window as if it were a 81x26 graph. I have just supplied sample inputs to test this out, but for some reason the shapes are not printing with the appropriate orientation to what should be the x and y axises. I have tried a bunch of different ways of trying to fix this problem and have had no luck. Hoping someone can help. Thanks

Looks OK to me:

It's not perfectly round because characters are taller than they are wide.
EDIT: That's only the first few rows on my output. Based on the comment and a second look at the code, I think rows and columns are getting mixed up.
for (int col = 80; col >= 0; col--) {
for (int row = 25; row >= 0; row--) {
cout << drawSpace[row][col];
}
cout << "\n";
}
There's a newline after every "column". Swapping the two for lines may produce what you want.
