Homework # 6
In this homework, you will write a templated class hierarchy for sets and maps.
The class GTUSetBase is an abstract class with the following pure virtual member functions.
| empty | |
| Test whether container is empty | |
| size | |
| Return container size | |
| max_size | |
| Return maximum size | |
| insert | |
| Insert element, throws exception std::bad_pafram if the element is already in the set | |
| erase | |
| Erase element | |
| clear | |
| Clear all content | |
| find | |
| Get iterator to element | |
| count | |
| Count elements with a specific value | |
| begin | |
| Return iterator to beginning | |
| end | |
| Return iterator to end | |
The class GTUSet<T> derives from the base class and implements all of the functions appropriately. It will keep its data using dynamic memory techniques with shared_ptr STL pointers. Do not use regular pointers or STL container classes.
The class GTUMap<K, V> derives from GTUSet<std::pair<K, V> > and implements the following extra function
| operator[] | |
| Access element | |
| V& operator[] (const K& k);If k matches the key of an element in the set, the function returns a reference to its mapped value. | |
The class GTUIterator implements iterator operators such as *, ->, ++, , =, and ==.
You will also write the following global function
template <class T>
std::shared_ptr<GTUSetBase<T> > setIntersection<T> (const GTUSetBase<T>&, const GTUSetBase<T>&); The returned set is the intersection of the two sets
Write your driver program to test the all the classes and all of their functions. Do not forget to test the global function with sets and maps.
