From your question it is not clear what you want to do. Before you can do anything in programming you need to have it clear and express it in plain english.

Do you want to convert an integer variable into a string representation of different bases (binary, hex & octal)? And convert a string representations of a number (with binary/hex/octal) back to an integer?

There's various ways you can do this, are you supposed to code the conversion from scratch or use libraries?

The binary conversion is very easy to do from scratch, with a for loop and some bit shifts.

The hex conversion is easy enough too you can use the %x in a printf, or use std::hex in a cout statement. I think think you can also use std::hex in a cin or a buffered string also, to do the opposite conversion.

Did you try Google? Also I think you should have taken note of what the mod posted on your last thread.

There are probably APIs for doing it but the easy way if you had to write your own is to create a lookup table. Base 2 to Base 26.
