Objectives

In this lab you will review using arrays in programs as well as begin to use the Eclipse environment.

Requirements

Create a program that will declare and initialize an array with the date given below. Your program should then compute and display the total of the elements in the array, the average of the elements in the array, the maximum value in the array and the minimum value in the array. The values you should get from this data are displayed below. The text has examples that you can use as models.

Here is the data:

2683, 2654, 3090, 3325, 4881, 3300, 7456, 3780, 3232, 7270,

7773, 5553, 2850, 7619, 2762, 6965, 4539, 3131, 6066, 5404,

4183, 6830, 2424, 4517, 6599, 3714, 7351, 4243, 6688, 7819,

6449, 3781, 5565, 3283, 7427

Max value

Min value

7819

2424

Total

175206

Average

5005.885714

There are several important points that are general requirements for labs in this course:

§ Use a separate Eclipse project for each lab, unless otherwise instructed.

§ The name of the project should include your name as part of it. For example, I might name the project today \'Lab_1_Sarah\'. Note, you specify the name of the project when you create the project.

§ Include a comment at the beginning of each source file you submit that includes your name and the lab date.

§ Names for variables and other program components should be chosen to help convey the meaning of the variable.

Turn in an archive of the entire Eclipse project for each lab. Do not attempt to turn in individual files, some course management systems mangle such files.
