Printing Output

• You can print output to the the screen (STDOUT) using the print() function

print("Hello world\n"); #print hello world, followed by a newline

As with most functions, the parenthesis are optional:

print "Hello world\n"; # same thing

$a = "10";

print "$a"; # 10

print $a * 5; # 50

print "$a * 5"; # 10 * 5
