/* 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

|
[x] bounding box as typedef struct
