Hi Reza,
we may prevent Power to gobble up terms by e.g. converting the terms
into a string. If you then copy the resulting expression to the
clipboard as "plain text" the quotes are not copied. Here is an example:
(1+a)^3+(1-a)^5/.Power[x_,n_Integer]:>Nest[#<>"*("<>ToString[x]<>")"&,"1",n]
there is an superfluous 1* that will not hurt.
hope this helps, Daniel

After computing the terms, I use the "InputForm", and then give the results to FFC compiler. The problem is that FFC does not accept "power" function. Therefore, terms such as "a^2" must be written as "a*a". Because there are many terms in the weak form of my problem, manual conversion of power terms takes a long time (and probably is subject to errors).
