2.4.4 String Operators

The final set of operators that we will consider are those that operate specifically on strings. Remember, though, that we can use numbers with them, as Perl will do the conversions to strings when needed.

The string operators that you will see and use the most are . and x. The . operator is string concatenation, and the x operator is string duplication.

use strict; my $greet = "Hi! "; my $longGreet = $greet x 3; # $longGreet is "Hi! Hi! Hi! " my $hi = $longGreet . "Paul."; # $hi is "Hi! Hi! Hi! Paul."
