So Iwas playing with the newly standardized unordered_map from the STL.The code I have is kinda开发者_开发问答 like this, I just create an unordered_map, fill it up, and print it out:
I want to store ~3,000,000 double values at unsigned int indices under VS2010 C++. I use a std::tr1:unordered_map<unsigned int, double> for this purpose. Unfortunately, when I try to store value
I\'m trying to use an iterator to output an integer in a multilayered unordered_map and I\'m having trouble with it, the error is below the code.
I have the following code where I wanted to eliminate the element I created initialy with the value 10. I\'m having trouble setting up an iterator and erasing it. How is it done?
In the program below I\'ve a typedef map. What I want to do is to implement a hash table. I\'m trying to use unorder开发者_如何学Goed_map since I heard that is the efficient as it takes O(1) time. I u
I have a few problems regarding a custom allocator for an unordered_map. I have a large dataset and I need to hash on a string as key. So I came to know that providing a custom memory allocator would
I am new to a lot of these C++ libraries, so please forgive me if my questions comes across as naive.
How can I sort an u开发者_StackOverflow社区nordered_map by key? I need to print an unordered_map sorted by key.std::unordered_map<int, int> unordered;
I\'m using the std::unordered_map from gnu++0x to store a huge amount of开发者_StackOverflow社区 data. I want to pre-allocate space for the large number of elements, since I can bound the total space
Is there a reason that std::tr1::unordered_map left out the equality (==) operator, which exists for std::map ?
