Question

I have a string of the following form :

"(number) number"

So for example it may contain :

5 (5)

or

5 (3)

I wish to create an int variable which will hold the first value (in both cases 5), and a second int variable which will hold the value in the brackets (5 in the first case, 3 in the second).

What is the best way for me to parse this string and save the info in the variables as I wish?

Answer 1

my $str = "(5) 3";
my ($x, $y) = $str =~ /\d+/g;
print "$x\t$y\n";

If you are not sure that input has exactly two numbers, then safer code is:

my $str = "(5) 3 4 (8)"; 
my ($x, $y) = ($str =~ /\d+/g)[0..1]; 
print "$x\t$y\n";
