Question

C++ Code! This code was written/implemented using the "class format." How would I go about in converting it to the "struct format?"

#include <iostream>

#include <iomanip>

using namespace std;

class ListNode{

public:

string course_name;

string course_number;

string course_room;

ListNode* next;

ListNode(){

this->next = NULL;

}

ListNode(string name, string number, string room){

this->course_name = name;

this->course_number = number;

this->course_room = room;

this->next = NULL;

}

};

class List{

public:

ListNode* head;

List(){

this->head = NULL;

}

void insert(ListNode* Node){

if(head==NULL){

head = Node;

  

}

  

else{

ListNode* temp = head;

while(temp->next!=NULL){

temp = temp->next;

}

temp->next = Node;

}

}

void print(){

ListNode* temp = head;

while(temp!=NULL){

cout << left << setw(20) << temp->course_name

<< setw(10) << temp->course_number

<< setw(10) << temp->course_room << "\n";

temp = temp->next;

}

}

};

int main() {

List l;

ListNode* n1 = new ListNode("Calculus 1","Math 1","SCMA 221");

ListNode* n2 = new ListNode("C++ Programming","CSP 31B","SCMA 150");

ListNode* n3 = new ListNode("Discrete Math","CS 55","SCMA 127");

ListNode* n4 = new ListNode("Java Programming","CS 26A","SCMA 352");

l.insert(n1);

l.insert(n2);

l.insert(n3);

l.insert(n4);

cout << "Courses for Tim Apple:\n";

l.print();

  

return 0;

  

}

Answer 1

structures:

structure is a collection of heterogeneous type of data means different data types under a single name.

and stucture is similar to class , both holds a collection of different data types.

syntax: struct structure_name

{

type variable_name;

type variable_name;

................  

} structure_variable;

#include <iostream>

#include <iomanip>

using namespace std;

struct ListNode {

string course_name;

string course_number;

string course_room;

ListNode* next;

ListNode(){

this->next = NULL;

}

ListNode(string name, string number, string room) {

this->course_name = name;

this->course_number = number;

this->course_room = room;

this->next = NULL;

} };

struct List {

ListNode* head;

List() {

this->head = NULL;

}

void insert(ListNode* Node) {

if(head==NULL) {

head = Node;

  }

  else {

ListNode* temp = head;

while(temp->next!=NULL) {

temp = temp->next;

}

temp->next = Node;

}

}

void print() {

ListNode* temp = head;

while(temp!=NULL){

cout << left << setw(20) << temp->course_name

<< setw(10) << temp->course_number

<< setw(10) << temp->course_room << "\n";

temp = temp->next;

}

}

};

int main() {

List l;

ListNode* n1 = new ListNode("Calculus 1","Math 1","SCMA 221");

ListNode* n2 = new ListNode("C++ Programming","CSP 31B","SCMA 150");

ListNode* n3 = new ListNode("Discrete Math","CS 55","SCMA 127");

ListNode* n4 = new ListNode("Java Programming","CS 26A","SCMA 352");

l.insert(n1);

l.insert(n2);

l.insert(n3);

l.insert(n4);

cout << "Courses for Tim Apple:\n";

l.print();

  return 0;
