Say, I have a std::vector<SomeClass *> v; in my code and I need to access its elements very often in the program, looping them forward and backward .
I have a code that looks something like: struct Data { int value; }; class A { public: typedef std::deque<boost::shared_ptr<Data> > TList;
Suppose I have a vector<int> myvec and I want to loop through all of the elements in reverse. I can think of a few ways of doing th开发者_如何学Gois:
I have a bunch of containers of object pointers that I want to iterate through in different contexts to produce diagnostics for them. I\'m struggling with the syntax required to define the functions..
I\'m using the following code to get an array of directories and their sub-directories where each contain file type extension: png. It works great but I need to 开发者_如何学Pythonbe able to output th
Does Python offer a way to iterate over all \"consecutive sublists\" of a given list L - i.e. sublists of L where any two consecutive elements are also consecutive in L - or should I write my own?
Starting from Visual Studio 2010, iterating over a set seems to return an iterator that dereferences the data as \'const data\' instead of non-const.
Having a hard 开发者_开发知识库time fixing this or finding any good hints about it. I\'m trying to loop over one file, modify each line slightly, and then loop over a different file.If the line in the
I am a C++ newbie trying to use a map so I can get constant time lookups for the find() method. The problem is that when I use an iterator to go over the elements in the map, elements do not appear i
So I have a Tree<E> class where E is the datatype held and organized by the tree. I\'d like to iterate through the Tree like this, or in a way similar to this:
