Concepts to Practice User-written functions math.h Description For the prelab assignment, you are to write a function called log16() to calculate the logarithm base 16 of a number. You may call any function from math.h such as log() or log10() in your implementation of log16). In your main(), you should loop through powers of 2 starting at 1 (which is 2) up through 4096 and print these numbers along with their log16() - see sample output below. If (like me) you need a refresher on how to convert logarithms, here is some info from Purple Math (https://www.purplemath.com/modules/logrules5.htm): In order to evaluate a non-standard-base log, you must use the Change-of-Base formula: Change-of-Base Formula: logo (x) = loga(x) log.b) What this rule says, in practical terms, is that you can evaluate a non-standard-base log by converting it to the fraction of the form "(standard-base log of the argument) divided by (same-standard-base log of the non-standard-base)". I keep this straight by looking at the position of things. In the original log, the argument is "above" the base (since the base is subscripted), so I leave things that way when I split them up: logna) logam logh(x) = log alb
