Given my druthers, I'd avoid long if tests in the first place. I'd rather do something like:
bool fTest1 = A == B ;
bool fTest2 = C ;
bool fTest3 = f(1,2,3) ;
bool fSuccess = ( fTest1 | ftest2 ) & fTest3 ;
if ( fSuccess )
...
Otherwise something like this:
if ( A == B
&& ( C == D
|| E == F
)
&& Z > Y
) {
...
}
else
{
...
}
YMMV, of course.
The former is far easier to debug, test, log, etc.
