Question
Write a program that explains the symbolic table clearly.
Answers
In Perl, the symbol table is a hash that contains the list of all the names defined in a namespace and it contains all the functions and variables. For example:
Perl
sub Symbols
{
my($hashRef) = shift;
my(%sym);
my(@sym);
%sym = %{$hashRef};
@sym = sort(keys(%sym));
foreach (@sym)
{
printf("%-10.10s| %s
", $_, $sym{$_});
}
}
Symbols(\%Foo::);
package Foo;
$bar = 2;
sub baz {
$bar++;
} 123456789101112131415161718192021222324252627282930313233343536
sub Symbols { my($hashRef) = shift; my(%sym); my(@sym); %sym = %{$hashRef};  @sym = sort(keys(%sym)); foreach (@sym) { printf("%-10.10s| %s
", $_, $sym{$_}); } } Symbols(\%Foo::); package Foo; $bar = 2; sub baz { $bar++; }
