Answer Posted / mukesh
for and foreach are alias of each other.But syntax is different.
e.g for(my $i = 0; $i < 3; ++$i){print $i}
e.g foreach my $i (0 .. 2){print $i}
i.e in foreach we can take always only array of elements or
range of elements.But in for we dont have to take the array
or range always.here we can provide condition of the loop
where it is not true for foreach.
