Answer the following questions true (T) or false (F)
1. STL ranges [first, last) are always ‘half-open’ – from the first element to a designation for one past the last element.
2. Given a map m, the expression m["value"] will return NULL if there is no string named "value" stored in the map.
1. True
Explanation: Note the begin() and end(),and the rbegin()and rend() member functions that all the sequence containers have. They provide a ‘half open’ range from the first element in the container to one past the last. The rbegin() and rend() members provide a range from the last to past the front, as a reverse_iterator would traverse.
2. False
This will actually add a new entry to the map associated with the key "value" that has the default entry for the map container type.
