What differences between monarch and president?

A monarch typically inherits their position and serves as a symbolic or ceremonial leader, often with power limited by a constitution or parliamentary system. In contrast, a president is usually elected by the public or an electoral body and holds executive authority, often with responsibilities for governance and decision-making. Monarchies can be absolute or constitutional, while presidential systems vary in their degree of power and responsibilities. Overall, the main differences lie in the method of obtaining power and the scope of authority.
