tabs to spaces with dev c++ v.4
i was just working with dev c++ v.4 and i have a question on the environment options part. it gives the option for (having to do with spacing and indentation) to have tabs into spaces. what does this mean and do? i first assumed that it simply just used tabs (so, for instance, you hit "tab" and then if you hit "backspace" it would delete that whole tab -- but apparently this ide just, when you hit "backspace" spaces back just one space, not the whole tab) as spaces, but i'm not sure now and i cant seem to figure it out. can anybody help me out with this?
