c++ - Outer class containing inner class - instantiate the inner class as a member of the outer class -

-

Currently I am trying to compile the following code:

terminallog.hh 

  #ifndef TERMINALLOG_HH # defined TERMINALLOG_HH #include & lt; String & gt; # Include & lt; Sstream & gt; # Include & lt; Iostream & gt; Class terminology {public: terminology (); Virtual ~ terminology (); Class warning {public: warning (); Private: Child lines; }; Friend class terminology :: warning; Protected: Private: Warning Warning; };   
 terminallog.cc  
  // stripped code Terminallog :: Terminallog () (this warning-> warning;} Terminology :: Warning :: Warning () {This-> lineended = true;} // hidden code   
 OK, as you're probably estimating ARDA, its failure ;-) My compiler is saying:  
  G ++ src / terminallog.cc inc / terminallog.hh -o test -Wall -Werror file contains src / terminallog.cc: 8: src / ../ Inc / terminallog.hh: 56: Error: Terminallog: Warning Terminology :: Warning Src /../ inc / terminallog.hh: 24: Error: Conflict with Previous Declaration Zero Terminal :: Warning (Std :: string) a ????   
 Leaves me out of options I am clearly doing something wrong, although I do not know how to solve it. I appreciate any pointers.  
 thanks in advance

  Warning (); Valid C ++ syntax is not valid - If you want to initialize the  warning  member, then use the initial list (in this case - the default constructor is said to be contained!). . Terminallog :: Terminology (): Warning () {// Other Constructor Code} // Note that 'Warning: Warning ()' applies to 'awake' inherently applied , Then Terminal Log :: Terminology () {} // will be

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.

Python's equivalent for Ruby's define_method? -

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)
