Why do shotguns not have rifling?

Most shotguns are not rifled inside. With standard ammo like lead or steel shot, a rifled barrel would cause the pieces of shot to bunch up into a tighter pattern, which would defeat the purpose of using a shotgun. For shooters who to more tightly control the spread and impact point of their shot, there are chokes.

Does a shotgun have a rifled or smooth barrel?

Many shotguns come standard with a smooth bore barrel because that's what you need to have to shoot shot (shells that have bbs or multiple projectiles – these are used in bird hunting and other sporting situations). In addition to shooting shot, you can also shoot slugs out of a smooth bore barrel.
