I feel that I should use sort with some kind of comparator but I'm lost right here: std::sort(vectorOfPairs.begin(), vectorOfPairs.end(), MyComparator); bool MyComparator(pair<int, int> a, pair<int, int> b) { if(some_kind_of_comparison){ return true; } return false; } I...

2. Using Custom Comparator If you don’t want to use the default order, you can write your own comparator and pass it to thestd::sortfunction. A comparator takes two pair objects and returns a bool indicating whether to put the first value before the second value. A comparator can be ...

VS 2015不显示相关的调试数据,只有原始的内存数据,这是因为在VS之后的新版本加入一个新的功能,可以自定义设置相关的数据显示格式,而在VS2015中相关的显示格式没有像VS2013等前期版本的那样做。 一、现象 最近使用vs2015调试C++程序,结果发现了一个很奇怪的问题:调试时无法查看stl里面string,vector,list等容器类的值...
