The error is correct -- you can't do that in todays C++. Have you been introduced to [FONT=Courier New]new[/FONT]/[FONT=Courier New]delete[/FONT]?

You may want to make your tables -- and [I]dummy[/I] input --have [FONT=Courier New]int[/FONT] type. A character [FONT=Courier New]0[/FONT] ([FONT=Courier New]'\0'[/FONT]) is not the same as [FONT=Courier New]'0'[/FONT]. Either that, or use [FONT=Courier New]'0'[/FONT] and [FONT=Courier New]'1'[/FONT] in the [FONT=Courier New]char[/FONT] table.

You're actually entering the [FONT=Courier New]%[/FONT] character, aren't you? If so, you'll need to use more complicated input handling, because the [FONT=Courier New]%[/FONT] character is not a valid character in a floating point representation; or else consider entering a fraction such as [FONT=Courier New]0.1[/FONT].
