perl - How to make an object into an array reference? -

-

मेरे पास यह फ़ंक्शन है 

  array_diff (\ @ DNs, \ @prev_DNs);   
 को सरणी संदर्भों को तर्क के रूप में रखना चाहिए।  
 समस्या यह है कि मुझे  prev_ns  से ऑब्जेक्ट के रूप में  
  मेरे $ prev_Ns = YAML :: Syck :: LoadFile ('temp-previous_DNs.yaml'); प्रिंट डम्पर $ prev_DNs;   
 जो आउटपुट करता है  
  $ VAR1 = ['abcdef'];   
 मैंने कोशिश की है  
  array_diff (\ @ DNs, \ $ prev_ns);   
 लेकिन वह काम नहीं कर रहा है।  
 कोई भी सुझाव देता है कि कैसे  $ prev_Ns  एक सरणी संदर्भ को पास करें?  < / Div> 
 
 
 यह पहले से ही एक सरणी संदर्भ है, वास्तव में तो आप वास्तव में संदर्भ के संदर्भ को एक और के साथ prefixing करके पास कर रहे थे। आपको बस इसे  $ prev_dns  के रूप में देना होगा और इसे कार्य करना चाहिए।

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
