C++ choose overloaded constructor for a stack object by condition -


i want this:

if (customlocation.isempty()) {     kurl url; } else {     kurl url(customlocation); } /* use url */

any reason can't do

kurl url; if (!customlocation.isempty()) {     url = kurl(customlocation); } /* use url */

or
