Map Index Operator

<source lang="cpp">

1. include <map>
2. include <iostream>

using namespace std; class Data { public:

 Data(int val = 0) { mVal = val; }
 int getVal() const { return mVal; }
 void setVal(int val) {mVal = val; }

protected:

 int mVal;

}; int main(int argc, char** argv) {

 map<int, Data> dataMap;
 dataMap[1] = Data(4);
 dataMap[1] = Data(6);
 return (0);

}

use map as an array

<source lang="cpp">

1. include <algorithm>
2. include <iostream>
3. include <map>
4. include <utility>

using namespace std; int main( ) {

  const char* word[] = { "A", "B", "C", "D","E" };
  const char* clue[] = { "a", "b","c", "d","e" };
  map<string,string> dictionary1;
  transform( word, word+sizeof(word)/sizeof(word[0]), clue,inserter( dictionary1, dictionary1.end() ),make_pair<string,string> );
  cout << "There are " << dictionary1.size() << " words in the dictionary\n\n";
  cout << "The clue for POPS is \"" << dictionary1["POPS"] << "\"\n"
     << "The clue for TAT is \"" << dictionary1["TAT"] << "\"\n"
     << "The clue for ESPO0 is \"" << dictionary1["ESPO0"] << "\"\n";
