c - Initializer element code error -

-

जब मैं कोड के इस भाग को चलाता हूं: 

  void main () {int a = 5; स्थैतिक int i = a + 5; Printf ("% d", i); }   
 मुझे त्रुटि मिलती है:  प्रारंभिक तत्व स्थिर नहीं है   
 इसका क्या अर्थ है?   < P> 
 
 फ़ंक्शन गुंजाइश में स्थिर चर डेटा सेगमेंट में जाते हैं। कंपाइल समय पर डाटा सेगमेंट आरम्भिक किया जाता है। इसका मतलब है कि प्रारंभिक मान को संकलन समय पर जाना जाना चाहिए। आपके मामले में, प्रारंभिक मान (ए के मूल्य) स्टेक पर एक वैरिएबल से आता है जो केवल रनटाइम पर उपलब्ध है।

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)
