*use data structure and object oriented programming language to solve the followin
you are required to do the following :
Add the following nonmember functions A nonmember function that read the Linked List info from a text file (info.txt) A nonmember function that write the linked List info to a new text file (new.txt) SeparateList: this function takes a linkedListType of students and two ArrayListType of students; if the student GPA>3 add it to List1 objects otherwise add it to List2, use the following prototype: void SeparateList (LinkedListType * obj, ArrayListType&List1, ArrayListType&List1);
* if you have a 1) class Student and 2) linkedListType.h and 3) ArrayListType.h
suppose that class student has a private attribute (double gpa ) and has setters and getters and whatever ....
suppose the ArrayListType has the following (suppose you knoe the implementation )
class ArrayListType { template
public: // Constructor ArrayListType(int size=10); ArrayListType(const ArrayListType& obj); const ArrayListType& operator=(const ArrayListType &obj); bool isEmpty() const; bool isFull() const; int listSize() const; int maxListSize() const; void print() const; bool isItemAtEqual(int location, const Type& item) const; void insertAt(int location, const Type& insertItem); void insertEnd(const Type& insertItem); void removeAt(int location); void replaceAt(int location, const Type& repItem); void retrieveAt(int location, Type& retItem) const; void clearList(); int seqSearch(const Type& item) const; void insert(const Type& insertItem); void remove(const Type& removeItem); int& operator[](int index); const int& operator[](int index) const;
