Explanation
- Constants:
MOVE_SPEED: Defines how much the object moves per key press.
- printPosition Function:
- Outputs the current position of the virtual object in 3D space.
- handleInput Function:
- Handles user input to move the object.
- Uses
_kbhit()and_getch()from<conio.h>to check for and get keyboard input. - Moves the object based on the pressed key:
Wmoves the object forward (decreaseszcoordinate).Smoves the object backward (increaseszcoordinate).Amoves the object left (decreasesxcoordinate).Dmoves the object right (increasesxcoordinate).Qmoves the object up (increasesycoordinate).Emoves the object down (decreasesycoordinate).Xexits the simulation.
Advertisement - Main Function:
- Initializes the position of the virtual object at the origin (0,0,0).
- Displays control instructions.
- Enters an infinite loop where it continuously prints the object’s position and handles user input.

Usage
- Initial Position: The virtual object starts at the origin (0,0,0).
- Controls: Use the specified keys to move the object in 3D space. Press
Xto exit the simulation.
