I'm trying to create a sieve (prime sieve). A nice quick simple one using boolean expressions. I remember on Visual Basics it began by creating like X number of boolean variables and then sieve them out by classifying them as false... and so on. How to a create a large group of boolean variables? I think it was something like p(i) and i=X, which X determined how many to create. It was something like this I think. So, technically i is like a variable itselt because when I go through the loop, I should be able to go through steps like... p(4) = false; p(6) = false; p(8) = false; ... all the way until I reach 2X. So, how do you create this variable? Thanks, I appreciate it.
