Why for loop is used in array?

If we know how many loop iterations we need before the loop begins, a for-loop is out best choice. In this example, the array is larger than needed, which means that some of the array is unused. The variable count drives the for-loop so only the filled array elements are accessed and the unused elements are ignored.
