MapType theMap;
Referring to the code sample above, which one of the following blocks of
code displays the string contents of the entire map theMap?
a) MapType::iterator it = theMap.first();
while(it!= theMap.end()) std::cout << it;
b) MapType::iterator it = theMap.begin();
while(it!= theMap.end()) std::cout << theMap[it];
c) MapType::iterator it = theMap.begin();
while(it!= theMap.end()) std::cout << (*it++).second;
d) MapType::iterator it = theMap |
