Ranges of arrays program in C#

Ranges of arrays program in C#
Write a program that: 
Reads 10 numbers, one by one, using a for loop. Use switch-case statement to do following: If the number is between 1 and 5, store it in one array, if the number is between 6 and 10, store it in a second array, if the number is between 11 and 15 store it in a third array. In all other cases display a message saying “The number is out of range! Enter a number between 1 and 15”.
         In the end, display the elements of each of the three arrays with some type of heading.
