perl function qq
www.igiftmoc.aedi
The qq function in Perl is used to quote a string with double quotes, similar to the "" operator. It is used to create interpolated strings where variables and escape sequences are replaced with their values.
Here is an example:
my $name = "John"; my $age = 25; my $str = qq(My name is "$name" and I am $age years old.); print $str;
Output:
My name is "John" and I am 25 years old.
In the above example, the qq function is used to create a string containing the value of $name and $age. The variables are enclosed in double quotes and the string is interpolated, which means the values of the variables are replaced with their actual values in the string.
