STL & Generic Programming: STL Container Iterators

Listing 2: Breaking a single line of code into many

// This is equivalent to the body of the while-loop in <a href="/showArticle.jhtml?documentID=cuj0104becker&pgno=2">Listing 1</a>.
//
std::pair<std::string, int> pairNewEntry(strCurrentWord, 0); // 1
std::pair<std::map<std::string, int>::iterator, bool>        
   pairInsertResult = mapWordCount.insert(pairNewEntry);     // 2
std::map<std::string, int>::iterator 
   itEntryInMap = pairInsertResult.first;                    // 3
++(itEntryInMap->second);
