Overloading

• Different functions with the same name but different arguments: overloading
• Often used when different algorithms exist to obtain the same aim with different data types
  

  void getInput(int theInput) {
  std::cout « "an integer" « std::endl;
  }
  void getInput(std::string theInput) {
  std::cout « "a string" « std::endl;
  }

• Can be used in recursive algorithms to differentiate initialization and recursive step
  

  void retrieveData(std::string URL, int maxDepth, Digraph& G,
  bool localOnly, bool verbose);
  void retrieveData(std::string URL, int maxDepth, Digraph& G,
  bool localOnly, bool verbose,
  int currentDepth, VertexURL* vParent);
