Q13: Subroutines

• Take out a piece of paper and put your name on the upper right corner.

• Write a subroutine with one parameter, an array of doubles. The subroutine should return the average of the doubles in the array.

Hint: Arrays have a property called length which returns the length of the array.

int[] arr = { 2, 4, 6, 8 };  // arr.length is equal to four
