One way is to use the manipulators dec, hex and oct
There is no std bin manipulator as far as I know so you have to write those functions yourself.
However hex is easy to convert to bin and back. Take each hex character separately
and write the 4 bit bin equivalent.
e.g. 25b3 == 0010 0101 1011 0011 (the spaces are to make it easier to see)

Another way is to write a function with two arguments. One for the number to convert and one for the base.

Then just call this function when you need a conversion.

Like maybe a finance program that keeps all the amounts in pennies. Only when a report or display is need does the program need to display dollars and cents with a $ and a decimal point. So this program only needs to call the conversion function when an amount needs to be reported oir displayed.

This leaves a program free to keep data values in the most convenient form.
