You are going to implement a program that creates an unsorted list by using a linked list implemented by yourself. NOT allowed to use LinkedList class or any other classes that offers list functions. It is REQUIRED to use an ItemType class and a NodeType struct to solve this homework. The “data.txt” file has three lines of data 100, 110, 120, 130, 140, 150, 160 100, 130, 160 1@0, 2@3, 3@END You need to 1. create an empty unsorted list 2. add the numbers from the first line to list using putItem() function. Then print all the current keys to command line in one line using printAll(). 3. delete the numbers given by the second line in the list by using deleteItem() function. Then print all the current keys to command line in one line using printAll().. 4. putItem () the numbers in the third line of the data file to the corresponding location in the list. For example, 1@0 means adding number 1 at position 0 of the list. Then print all the current keys to command line in one…
Assume a Node class has been defined using the Node class implementation in your texttbook, except that the data members have been declared public instead of private. This means that the code shown below has direct access to the data members defined inside the Node class. Type the EXACT output of the following code segment. You may assume that the code compiles and executes without errors. Node *ptrl; Nodecchar> *ptr2; Node *top; char ch: ptr1 = new Node; top = ptrl; ptrl->item = 's'; ptrl = new Node; top->next = ptrl; ptr1->item = 'R'; for (ch = "E'; ch >= 'A'; ch--) ptr2 = new Node; ptrl->next = ptr2; ptr2->item = ch; ptrl = ptrl -> next; ptrl->next = nullptr; ptrl = top; while (ptr1 != nullptr) cout tem next;
I'm stuck on this question and I don't know how I should be approaching this. What should I do? My code so far: ----------------- #include <iostream> using namespace std; class Student{ public: Student():grade(0.0){} void setGrade(double value){ grade = value; } void setName(string value){ name = value; } void setMajor(string value){ major = value; } double getGrade(){ return grade; } string getName(){ return name; } string getMajor(){ return major; } void addStudent(double grade, string value1, string value2){ Student::setGrade(grade); Student::setName(value1); Student::setMajor(value2); } void display(){ cout<<"Name: "<<Student::getName()<<endl; cout<<"Major: "<<Student::getMajor()<<endl; cout<<"GPA: "<<Student::getGrade()<<endl; cout<<"Grade: "; } private: class GPA{ public: GPA(){} void getLetterGrade(double grade) const{ if (grade >= 3.5){ cout<<"A"; } if (grade >= 2.5…

1.A) The median of a set of integers is the middle-most integer in size. That is, half the integers in the set are less than or equal to the median, and half the integers are greater than or equal to the median. For example, the median of {99, 1, 10, 6, 2} is 6 since 1 and 2 are smaller than 6 and 10 and 99 are larger than 6. Implement a method median( ) with no parameters that finds and returns the median of the integers in a data array. Use this keyword in meaningfully. Assume that the data array is an instance variable of Data class. Write a parameterized constructor to allocate and assign values to data array. Assume that the array has odd length. Write main () in a separate class constructor to use the Data class.
