String Operators

• In Perl, there are two ways to concatenate a string:
• If you are printing it, simply include the string scalar in double quotes.  Example:

print "Welcome back $salutation $firstName $lastName";
• Remember, single quotes will return the string verbatim, but double quotes will evaluate the contents of the string and return the result.
• Otherwise, use the period:

$fullName = $firstName . $lastName;
$maleFullName = "Mr." . $firstName . $lastName;
• You can easily repeat a string in Perl by using the letter x and the number of times you wish to repeat the desired string.

$cheer = "Go Bearcats! " x 3;
• Interestingly, you can also use * to do the same thing.
