TRUE/FALSE question from an introduction to Arduino assignment

16. A suggestion your instructor found on the Internet (so it must be true) suggests one can solve overflow problem by declaring a variable as a long unsigned int. This declaration uses two 16-bit words to store a variable. The maximum value of an unsigned long int is 252 - 1 = 4,294,967,295 as opposed to 65,535 for an unsigned 16-bit int. Let's assume you are storing using the results from the millis() time function (this is a form of a counter). T/F: This is an effective solution to the overflow problem. (Hint: Calculate many days the maximum number of milliseconds you can store in an unsigned long int is and then compare length of time to how long you expect a machine you design would operate on a continuous basis.)
