C# Programming: How do I code this please ?

This problem requires use of a switch statement. The Society for Planetary Awareness has commissioned an application that tells which grouping a planet belongs to the inner planets, the outer planets, or beyond the planets. The application must accept an integer value from the user that represents a planet's position in order of distance from the sun (1 - Mercury, 2 - Venus, and so on). Respond to the user with a message based on this table: Position entered 1 2 3 4 5 6 7 8 9 >=10
