Question

私は初心者です。私はこれを持っています..

%categories = (
    'Announcements' => ['Auctions', 'Bands-Seeking-Members', 'Boutiques', 'Charity'],  
    'Appliances' => ['Dishwashers', 'Fireplaces/Wood-Burning-Stoves', 'Microwaves'],  
    'Auto-Parts-and-Accessories' => ['Auto-Accessories', 'Car-Audio-and-Video],  
    'Baby' => ['Baby-Clothing', 'Backpacks-and-Carriers', 'Changing', 'Cribs-and-Playpens'],  
    'Books-and-Media' => ['Blu-ray-Discs', 'Books:-Children'],  
    'Clothing-and-Apparel' => ['Boys-Clothing', 'Boys-Shoes', 'Costumes']  
);

これを印刷するために必要です..

• Announcements  
 -Auctions  
 -Bands-Seeking-Members  
 -Boutiques  
 -Charity  
•Appliances etc  

これはこれまでのコードです..

while( my ($cat,$subcat) = each %categories) {      
    print qq~• $cat
~;  
    print qq~- $subcat
~;  
}  

これを印刷しています..

• Clothing-and-Apparel  
- ARRAY(0x1e959c0)  
• Announcements  
- ARRAY(0x1e95590)  
• Auto-Parts-and-Accessories  
- ARRAY(0x1e95740)
