Example: Arrays (data structure)

This program illustrates these new concepts:

• arrays (data collections)
• document.write to put output onto a new browser page
• Math.random() to generate random numbers

This program illustrates the use of an array to group together data items that have different values, but are related in some way or used in some common fashion. Arrays give us the ability to group values into collections that allow us to access the individual values systematically.

Arrays are one example (widely used) of a general concept called "structured data", or data structures. This is grouping data items together in such a way that relationships amoung the data items are implied, and so that the group can be manipulated as a group when desired or as individual elements when needed.

Input

This version requires no user input. Data values are generated randomly, uniformly distributed between 0 and 100, and truncated to 2 decimal places.

Output

The program prints out the values grade values stored in the array. It then prints the average grade. It then prints the largest grade.

Termination

The program ends automatically.
