In Perl, what does a scalar variable always begin with? 1. @ 2. # 3. $ 4. %

The dollar sign ($) ...............

Scalar variables always begin with a dollar sign ($). For example, $example is considered a scalar variable, @example is considered and array, %example is considered a hash, and any line beginning with # would be remarked statement.
