Hi Thanks for the reply. I managed to write and execute my perl program.
Now my next question is , I am following the learning perl Llama book.
There in Chapter 1, there is a function used whose output is
perldoc -u -f atan2
=over 8
=item atan2 Y,X
Returns the arctangent of Y/X in the range -PI to PI.
For the tangent operation, you may use the C<Math::Trig::tan>
function, or use the familiar relation:
sub tan { sin($_[0]) / cos($_[0]) }
=back
for this script, they said there should be a different output for this
program as opposed to the above output
#!/usr/bin/perl
@lines = 'perldoc -u -f atan2';
foreach (@lines){
s/\w<([^>]+)>/\U$1/g;
print;
}
but all i get is
perldoc -u -f atan2
as the output.
Am i missing something.
thanks for looking in
