How can I know the equal_range didn\'t find any match cases? like: multimap<string,string> mapdic;
Beginner question -- what do you usually use as a multimap? I want a function that takes a labelling function and partitions elements by each label. For example,
The question whether a multimap preserves the insertion order of identical 开发者_StackOverflow社区keys has been asked numerous times and I think it is pretty clear that the standard says it doesn\'t.
I\'m looking for the corresponding way, for Multimap, to iterate over entries of a Map, namely: Map<K,V> map = ...;
I have a problem 开发者_如何学Cwith the creation of a hash of arrays. I need a Single Key - Multi Data system:
I\'m still seeking an ideal solution to this question. To summarize, I am modeling a power subsystem in Java and I need a Directed-Acyclic-Graph (DAG)-type container for my data.
For exam开发者_JAVA百科ple a C++ vector is implemented using a dynamic array where each element uses consecutive memory spaces.
I am trying to use multimaps in C++. The main aim is that there is a map that stores the multimap pointer.
We were using a multimap<int,string> to store several hundred thousand items (>300K), when we realized we needed to add more data for analysis. So we created a class that held a few items and th
EDIT: Please note, I\'m NOT asking why multimap can\'t contain duplicate keys. What\'s the rationale behind multimap allowing duplicate key-value pairs? (not keys)
