(C++) std::map

STL container for mapping two kinds of data types.

#include <map>

std::map<std::string, int> phonebook;

The std::string is the key (in this case a last name) and the int is termed the value (in this calse the persons telephone number).

One key can only have one value. If a key needs to have one or more values, use a std::multimap.

std::map code snippets

Note that among these are also more general container code snippets.

* IsKeyInMap, checks if a key is in a std::map

* GetValueInMap, get a value in a std::map

* Check if a key is in a std::map, IsKeyInMap

* Get a value in a std::map, GetValueInMap

* LoopReader, reading a container looped

* Reading a container looped, LoopReader

std::map compile errors

* 'operator+' not implemented in type 'std::map<int,double>' for arguments of type 'int'
