                    Data types in Perl are:

    Scalar
    Array
    Hashes
                

                    Scalar variables in Perl are a single unit of data. Different types of scalars in Perl are string, character, floating point, large group of string, webpage, etc.                

                    Hash in Perl are declared using the % sign.                

                    The elements of the array can be number, string, characters, etc.                

                    Array declaration in Perl is done using @.                

                    The valid way to extract the size of an array in Perl is:

    $size = scalar @array_name 
                

                    Hash in Perl is a set of key-value pairs.
