c++ - Destructor query -

-

I have this program, where I am passing a vector in the context of the function myFunc and Inside this function, I am adding some element to the vector.

I am not releasing the object with the new object, because now ignore the memory leak due to this.

After MyFunc () execution is complete I know how many times the constructor and the district was called.

Output is: 

  before 5 7   
 I am creating 5 objects so that  Ctor  is  5 . But why is  dtor   7 ? Where does the additional two counts? Am I missing something?  
  #include #include using namespace std; Stable int CTOR = 0; Fixed int dtor = 0; Classes Myclass {Public: Myclass (Int N) {i = n; Ctor ++; // cout & lt; & Lt; "MyClass CTOR" & lt; & Lt; Ctor & lt; & Lt; Endl; } ~ Myclass () {dtor ++; // cout & lt; & Lt; "Mylcass DTOR" & lt; & Lt; Dtor & lt; & Lt; Endl; } Private: int i; }; Zero myFunc (vector & lt; MyClass & gt; & amp; m); Zero myFunc (Vector   
 
 
 The vector creates a copy around the object, but only your  int < / Code> Manufacturers' increments  ctor . It is not accounted for copied objects, and because you have not provided one, the compiler has provided it for you.  
 Add  
  MyClass (const MyClass & amp; rhs) i (Rhs.i) {++ ctor; }   
 To see if he balances the count.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered. Especially when trying to connect like the example for Mono Touch string dbName = path. Cobain (environment. Gatefolder path (environment specialfolder personal), "mydb.db3"); // The following line will be called coolestation, where is the database, // to make it if it does not exist, and call a delegate that creates the necessary tables (only when the database file was newly created //) CSConfig.SetDB (DbName, true, () => {CSDatabase.ExecuteNonQuery ("Subscriber Integer Primary Key Attribute, Name Text (50) No, Number, Date First Text (30)");); There is no difference when I try to use the methods of CSConfig and when I cscfif If I try to pass 3 aggregates to STDB (3) then I get the invalid ...

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
