+/* Bounding Box 2D
+- = rectangle that completely encloses the circle (whole circle lies within the rectangle or on its boundary)
+- bounding box must be smallest possible rectangle that encloses the circle (square)
+[x] ask for x of the center of the circle
+[x] ask for y of the center of the circle
+[x] ask for radius of the circle
+[x] calculate 2D bounding box for given circle
+[x] print coordinates of 4 corners
+[x] print coordinates with 2 decimals
+[x] print as "Bounding Box - <CORNER_NAME>: (<X_COORDINATE> / <Y_COORDINATE>)"
+[x] order: TL (top-left), TR (top-right), BL (bottom-left), BR (bottom-right)
+[x] circle as typedef struct
