Implementation of Levenstein's distance in C++. If you are looking for simple/pure implementation of it, please refer Levenshtein.cpp->int levenshtein_distance(std::string target, std::string source, int kMaxCost). 

However, if the dictionary is big and you are looking for ways to boost performance, then you need to use trie data structure + Levenshtein distance algorithm. MyNode class implements simple tree structure and provides Levenshtein distance search.

Levenshtein.cpp file has testNode() and testDict() functions for code profiling. Use runLookup() method for term lookup.  

To compile:
g++ -g MyNode.cpp Levenshtein.cpp -lrt -o dict
