Circle draws a filled disk by iterating every integer cell within the axis-aligned bounding square around the center (xc, yc) and placing a Point for each cell whose distance from the center satisfies dx² + dy² ≤ radius². This approach is simple and correct without trigonometry, producing fully filled circles rather than outlines. Because Point::draw() enforces the safe-margin bounds check, cells near the console edges are automatically skipped. 
#include "include/headers/Circle.h"

​
Constructor

explicit Circle(float xc, float yc, float radius, short color, short character = 0x2588);
​
xc
float
required
Column position of the circle’s center.
​
yc
float
required
Row position of the circle’s center.
​
radius
float
required
Radius in console cells. The bounding square scanned is (xc - radius, yc - radius) to (xc + radius, yc + radius).
​
color
short
required
A ConsoleColor enum value applied to every filled cell (e.g. yellowF, blueF).
​
character
short
default:"0x2588"
Unicode code point written into each filled cell. Defaults to 0x2588 (█).

Methods

MethodReturnsDescription
draw()voidIterates the bounding square cell by cell and places a Point for each cell satisfying dx² + dy² ≤ radius².
translate(float dx, float dy)voidShifts the center by dx/dy. Applied only when the entire circle (center ± radius) stays within console bounds.
setCenterX(float) / getCenterX()void / floatCircle center X.
setCenterY(float) / getCenterY()void / floatCircle center Y.
setRadius(float) / getRadius()void / floatCircle radius.
setColor(short) / getColor()void / floatFill color attribute.
setCharacter(short) / getCharacter()void / floatFill character code point.

Example

#include "include/headers/Fazen.h"

Circle sun(50.0f, 10.0f, 8.0f, yellowF);     // yellow filled circle near top-center
Circle planet(30.0f, 30.0f, 4.0f, blueF);   // smaller blue circle

game.graphics.draw(sun);
game.graphics.draw(planet);

// Orbit the planet around the sun (simplified linear drift):
planet.translate(0.5f, 0.0f);
Console cells are not square pixels — a typical console font is roughly twice as tall as it is wide. As a result, circles may appear horizontally stretched (elliptical) depending on the font aspect ratio. To compensate visually, reduce the effective X radius or choose a font with a 1:1 aspect ratio such as a square pixel font.
