Simple with std::map

main.cpp

#include <iostream>
#include <string>
#include <map>

enum TMemoryValue{YES=1, NO, MAYBE, UNKNOWN};

int main () {
  std::map<std::string, TMemoryValue> memorymap;
  std::map<std::string, TMemoryValue>::iterator it;
  
  memorymap.insert(std::pair<std::string, TMemoryValue>("Peasant", UNKNOWN));
  memorymap.insert(std::pair<std::string, TMemoryValue>("Woodcutter", UNKNOWN));
  memorymap.insert(std::pair<std::string, TMemoryValue>("Stonemasson", UNKNOWN));
  memorymap.insert(std::pair<std::string, TMemoryValue>("Blacksmith", UNKNOWN));
  
  memorymap.insert(std::pair<std::string, TMemoryValue>("WoodWalls", UNKNOWN));
  
  //memorymap["Peasant"]=YES;
  (*memorymap.find("Peasant")).second = YES; //don't create Peasant if it dont exist...
  
  if((memorymap.find("Peasant") != memorymap.end()) && ((*memorymap.find("Peasant")).second == YES)){
    (*memorymap.find("Woodcutter")).second = MAYBE;
    (*memorymap.find("Stonemasson")).second = MAYBE;
  }

  for(it=memorymap.begin(); it != memorymap.end(); it++){
    std::cout << "Object: " << (*it).first << " (" << (*it).second << ")" << std::endl;
  }
 
  return 0;
}

Du kan använda std::make_pair för att korta ner koden.

memorymap.insert(std::make_pair("Peasant", UNKNOWN));
