unordered_map<eg,int,eg_hash>mp; unordered_set<eg,eg_hash>st; mp[eg(1,2)]=1; mp[eg(5,3)]=55; st.insert(eg(534,4235)); st.insert(eg(5,634)); getchar(); } 其中hash<int>()是一个hash模板类对象。该类重载了函数调用运算符,所以我们使用hash<int>()(xxxx)来计算xxxx的哈希值。

Set、Map: 对于map、set来说如果是基本类型,默认从小到大。但如果是自定义类型或者非基本类型(比如vector这种),那么就需要自己重载相应的规则。 举例: 我知道的map重载从大到小的几种方法: 1、Lambda: auto cmp=[](intx,inty){returnx>y;}; map<int,int,decltype(cmp)> p(cmp); ...
When using unodered_map, you need to specify two types as parameters - one for the key, and one for the value. E.g. std::unodered_map<int, std::string> Igor Tandetnik
