What's the difference between my ($variableName) and my $variableName in Perl? -

-

मेरे ($ variableName) और my $ variableName पर्ल में? कोष्ठकों को क्या करना है?

महत्वपूर्ण प्रभाव तब होता है जब आप एक ही समय में चर को प्रारंभ करते हैं इसे घोषित करें: 

  मेरी ($ a) = @ बी; # $ A = $ b प्रदान करता है [0] मेरी $ a = @b; # $ A = स्केलर @ बी (@ बी की लंबाई)

दूसरी बार महत्वपूर्ण है जब आप कई चर घोषित करते हैं। 

  मेरे ( एक, $ ख, $ C $); # सही, सभी चर को अब मेरी $ a, $ b, $ c; # $ ए को अब मौखिक रूप से स्कॉड किया गया है, लेकिन $ b और $ c नहीं हैं

यदि आप सख्त का उपयोग करें
