You can allocate a std::vector which allocates aligned heap memory by defining your own allocator. You can allocate a c-style array on the stack using declspec align. But can you declare a tr1::array which guarantees that the element at index zero will be aligned? ...

Hi everyone! Rookie C++ Programmer here again I'm using VC++ VS2008 and making an attempt at creating an array of arrays. All objects I wish to store I want to put on the heap. In the arrays it's all just pointers. Here's some code: Grid.h #include "Tile.h" class Grid { public: Tile* grid_ptr[8][8]; ... ... }; Grid.c...
Hi there, I'm looking for a way to store a serialized value of eg. IDs in a column. In before claims that this is not an optimal design: the column is used for IDs of associated records, but will only be used when displaying the record - so no queries are made with selection on the column and no joins will be made on this column either....

The code seems to be working only on the first array element which is 0. If I try to search for other records, it cannot find them. I don't know why. boolean blnFound=false; String strP=getString("Inpu...
Hello everyone, I am trying to sort an array that contains numbers that range in substantial values.

I was going through the exercises at http://rubykoans.com/ and I was struck by the following Ruby quirk that I found really unexplainable: array = [:peanut, :butter, :and, :jelly] array[0] => :peanut #OK! array[0,1] => [:peanut] #OK! array[0,2] => [:peanut, :butter] #OK! array[0,0] => [] #OK! array[2] => :and #OK! array[2,2] ...

I have a string of tags that are usually separated by a single space, but the spacing may be inconsistent due to user input, hence the multiple spaces I added. $somestring = "<h1> <a> <h5> <img> <a> <strong>"; I'd like to store the tags into an array instead for easier manipulation. How can this be done with PHP? ...
I have a 2-dimensional array of pointer to char and initialising it in a header file. The problem is this: it doesn't complain getting assigned a const char[] but does not like me assigning const char* (as shown in the code). It gives me an error "initializer element is not constant". const char lang[8] = "English"; const char * langPt...
