Imagine that you are trying to store 32 Boolean values, and must access them frequently. Compare the time required to access Boolean values stored alternately as a single bit field, a character, a short integer, or a long integer. There are two things to be careful of when writing your program. First be sure that your program does enough variable access to make meaningful measurements. A single access takes much less time than a single unit of measurement (typically milliseconds) for all four methods. Second, be sure that your program spends as much time as possible doing variable accesses rather than other things such as calling timing functions or incrementing for loop counters.
