How does a variable's amount of space used correlate to its ablity to hold data. For example do a Char and an Int use the same amount of memory, or does a Char use less because it only needs to store numbers 0-255? Also if a charecter is written to a file does the file really contain 3 numbers representing the letter, or is it saved in bianary (or perhaps some other base system)?
Thanks,
