Swapping sections of an array with each other in C++ -

-

Is there an easy way to swap the squares (sections) of arrays with each other? That is, I have an array: 

  array [0] = 1; Array [1] = 2; Array [2] = 3; Array [3] = 4; Array [4] = 5; Array [5] = 6; Array [6] = 7; Array [7] = 8; A function called   
 and  swapSections (startX, endX, startY, endY) that these values ​​are given too much,  limit the values ​​set by endX Swaps - startX  with values ​​from  x range to  start  to  endY , so from my example ...  < P> If  x range = 2  and  startX = 0  and  y category = 3  and  startY = 5 , it The array [0] and the array will give the space [1] where the array [5] and the array [6] are, and then the array [6] holds after the array [7] All of which are pushed down one by the other, I'm not sure how to go about this, and I was physically copying memory into a temporary array, but I think there is a better way of doing this is. (BTW will be the last result from my example):  
  array [0] = 6; Array [1] = 7; Array [2] = 8; Array [3] = 3; Array [4] = 4; Array [5] = 5; Array [6] = 1; Array [7] = 2;    
 
 
 You want to see it and it's slice.

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.

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...
