size() Vs. length() vs. Storing Length Value Before Entering for Loop

Compares use of size(), length(), and stored length of array when used in a for loop

size() Vs. length() vs. stored array length when used in a for loop. This will ultimately show that the stored length is 17 times faster the using length() and 22 times faster than using size() in a for loop.
One must weigh the code savings by using size() and length() in a for loop. When only a few iterations are needed, size or length are inconsequential. For a large number of iterations, calculating the length of an array before entering a loop is preferred.
