  1. Scalar Data •In PERL, scalar data represents single values such as numbers, strings, and references.

PERL automatically handles the conversion between different data types, making it easy to perform operations on scalar values without worrying about type casting. Scalars can store any type of single value,

  Scalar Syntax • Syntaxfor declaring scalars in PERL: ```perl my $age = 25; my $name = "John"; my $salary = 50000.50; ``` In this example, we declare three scalar variables: $age (integer), $name (string), and $salary (floating-point number).
