I need to write a program that draws a grid with different symbols and spaces. The overall shape that is printed on the screen shoudl be a circle that looks like a tire and wheel. There should be different symbols for the hub, the wheel, and then the outer tire and the rest all spaces. The user reads in the circumference of the tire and the program converts it into a radius that is used for the grid to draw the tire. I know I need a for loop to draw the shape, but I am confused as to how to start the drawing from the center of the grid? Can anyone help.
