I think you are confusing value with representation. What you are
describing is an operation on the decimal representation of some integer
values. As both C and C++ (along with most other computer languages)
explicitly do not represent integer values in a decimal form whatever
you do will have to consider changing the representation to the one that
is relevant to the manipulation you wish to do.
The obvious way in C++ is to create a stringstream, feed the values into
it without whitespace and then read an int value out of it. That process
will automate all the conversions for you even if it is not particularly
efficient.
However there is a major question; why do you want to do this? Perhaps
the they should all be strings all the time.
