array intro
filling and retrieving

You can review the syntax for arrays from yeterday's lecture. Today's code can all be written in main.

• Create an array of five doubles. Initialize the contents of the array by reading their values from the keyboard.
• [If you covered the avg method in yeterday's lecture:]
  Print out the average value. (Call the method we wrote in class.)
• Write a loop to repeatedly: Ask the user which entry they want to see (a number in 1..5), and print out the contents of that one location. If the user types in a number that is not in 1..5, then quit. ( You don't need to worry about a non-integer being typed.)

Here is a sample transcript:

Please enter integer #1: 16.5
Please enter integer #2: 1.5
Please enter integer #3: 0
Please enter integer #4: 3
Please enter integer #5: 9

The average of the number is 6.0.

What number do you want to see? 2
Entry #2 is 1.5.
What number do you want to see? 5
Entry #5 is 9.
What number do you want to see? 8
Good-bye!
