Descending order in Map and Multimap of C++ STL

We have discussed map in C++ STL and multimap in C++ STL. The default behavior of these data structures is to store elements in ascending order. How to ensure revers...

unordered_multimap and its application

Allows Duplicates: We have discussed about unordered_map in our previous post , but there is a limitation, we can not store duplicates in unordered_map, that is if we...

multimap find() in C++ STL

multimap::find() is a built-in function in C++ STL which returns an iterator or a constant iterator that refers to the position where the key is present in the multim...

multimap::emplace() in C++ STL

The multimap::emplace() is a built-in function in C++ STL which inserts the key and its element in the multimap container. It effectively increases the container size...

Multimap in C++ Standard Template Library (STL)

Multimap is similar to map with an addition that multiple elements can have same keys. Rather than each element being unique, the key value and mapped value pair has ...

multimap::begin() and multimap::end() in C++ STL

multimap::begin() is a built-in function in C++ STL which returns an iterator referring to the first element in the multimap container. Since multimap container cont...

multimap::crbegin() and multimap::crend() in C++ STL

multimap::crbegin() is a built-in function in C++ STL which returns a constant reverse iterator referring to the last element in the multimap container. Since multim...
