My code: typedef pair<int,int> Pair tr1::unordered_map<Pair,bool> h; h.insert(make_pair(Pair(0,0),true));
How can I sort this vector by comparing the p开发者_JS百科air.first which is an std::string? (without providing a static compare function, nor use boost).std::vector<std::pair<std::string, bool&
suppose I have a s开发者_高级运维td::vector of pair. How can I use, efficiently, method std::find to see whether at least one element of the vector is not equal to (false, false)?
I have a private attribute in a class that is defined as vector<pair<char *, int> > data;. I add data to this vector with data.push_back(make_pair(p, r));. Later when I go to get the data
This question already has answers here: Closed 12 years ago. Possible Duplicate: What is the difference between using a struct with two fields and a pair?
I\'m new to Objective-C, so please don\'t judge me too much. I was wondering: Is there an equivalent of the C++ STL pair container I can use in Objective-C?
I\'d like to output some data to a file. For example assume I have two vectors of doubles: vector<double> data1(10);
I have got a std::list< std::pair<std::string,double> >, which I know is sorted according to the std::string ele开发者_开发问答ment.
In definition of pair class in c++ there are two typedefs. what are they for? there are no use of them in the code!
There are a couple of other posts about sorting a vector A based on values in another vector B. Most of the other answers tell to create a struct or a class to combine the values into one object and u
