STL’s Associative Containers
BRUCE R. SUTHERLAND · Apress eBooks · 2014
All of the STL containers you have seen so far have stored individual data elements. In this chapter you will be introduced to associative containers. These containers associate a key with the data values that you are inserting. In the case of the map and unordered_map containers, you are required to supply a value to use as the key, whereas the set and unordered_set containers automatically generate keys from the data you supply. I'll explain the differences between each of these containers as I work through some examples in this chapter, beginningwith the set container. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
