I am currently trying to add to a linked list in sorted order but I have reached an impasse. I can get it to add in sorted order if it belongs in the beginning or second in the list. If i were to type in 9 then 4 i would get 49, but if i type in 5 it changes it to 559. I'm just at a loss and need some sort of direction.
#include "singly_linked_list.h"
#include <iostream>
using namespace std;
void add_node(node*& head_ptr, const int& payload){
if (head_ptr == nullptr) {
node* my_node = new node();
my_node->data = payload;
I been ask to create a sorted linked list module, and to test each function with 1 unit, 2 +.so i wrote my addtofront function( we have to use the same as the teacher)
but i cant seem to test it because it always display a seg fault.... i dont know what i did wrong....how do i call this function in main to display a string i want?
So I've been working on a sorted linked list homework assessment and I've been stuck on a problem for a while now. Below is my code for inserting a new object into the linked list, for some reason it keeps crashing whenever I try to malloc temp. (between the "checkpoint" and "after malloc" printf statements) .
Code:
int SLInsert(SortedListPtr list, void *newObj){ SortedListPtr curr = list; SortedListPtr temp = NULL; if(list->obj == NULL) /*if the list is empty insert obj into the first node*/ { list->obj = newObj; free(temp);
// Write a function called insertEntry() to insert a new entry into a linked list.
Have the procedure take as arguments a pointer to the list entry to be inserted (of type struct entry as defined in this chapter), and a pointer to an element in the list after which the new entry is to be inserted.
// The function dveloped in exercise 2 only inserts an element after an existing element in the list, thereby prenting you from inserting a new entry at the front of the list.
(Hint: Think about setting up a special structure to point to the beginning of the list.)
This is a working version of the exercise, but I don't think I'm doing what's asked. I was able to add an element to the beginning of the list using an if statement, not creating a special structure that points to the beginning of the list. How would I go about creating a special structure that points to the beginning of the list to add a new element at the beginning of the list?
I wrote function to add to elements in the list, but when I call printList function it returns me empty list ! I'm new with linked list in C
Output:
Empty list List is empty add element at the begining New node with packet num 245 List is not empty add element at the end New node with packet num 486
Linked list: Empty
Main:
Code:
int main(){ struct node * start ; start = NULL; int i; /*Check if list is empty*/ if(start == NULL){ printf("Empty list
I've been struggling with linked list for a few days. I've tried performing a few operations. Here is my code. the add_begin() function doesn't seem to work.
#include<iostream> using namespace std; struct node { int data; node *next;
Ok so I am having difficulty adding nodes to my linked list....
how to add a third node while keeping track of the address...Thats where I get lost..I don't know how to keep track of the addresses of the next node..
#include <iostream> using namespace std; typedef struct Node{
I was trying to reverse a linklist in reverse direction using the recursion. I was able to reverse n - 1 element but it is not printing the first one. Below is my code.
Code:
typedef struct linklist { int data; linklist *next; };
void add(int data,linklist **node) {
[code]....
This is happening since recursion is starting from second node, which is due to reason not printing the first one when recursion print values from stack once
node != NULL
Condition is met.
Currently I am using below statement for printing the first element;
reverse_recur(node); printf(" Print In Reverse Order %d ",node->data);
At the line number 65 that's my sort method first i sum up all the value in the nodes after that i want to sort the Nodes In ascending order but the method is not working ...
#include <iostream> #include <conio.h> using namespace std; // Node Class
Now, when I iterate back through my list (I want to start at the tail and work my way towards the head), I can only ever get the 1st node to print, then the 2nd node is garbage, which means, to me, that I've linked something wrong.
I have a .cpp file which contains 5 smaller defined classes. In my missile class I have a default constructor and a constructor that I invoke
class Missile{ private: bool isHuman;
[Code]...
My issue is when creating and adding the pointer object; it doesn't seem to create a new instance of the class-the Missile objects all share the same xPos value which is always the first xPos when the "fire" command is given. The "Missile *missile = new Missile(xPos, yPos, true);" line does not seem to create a new instance of the object with different variables but instead creates a new object with the same variables. Is it necessary for me to always make a separate .cpp and .h file for any class I want to create multiple instances of or can I keep the smaller classes in the same file and still create a new separate instance of the class?
I need to make singly and doubly linked list classes that can insert elements. Once the lists are created, I need to order the linked list elements according to a certain pattern.
Implement a recursive function named void printBack(DoublyLinkedNode<T>* node) for the class DoublyLinkedCircularList which will print out the elements in the list from back to front. The function is initially called with the first node in the list. You may not make use of the previous(prev) links
This is my solution where I got 2 out of a possible 3 marks:
template<class T> void DoublyLinkedCircularList<T> :: printBack(DoublyLinkedNode<T>* node) { if(node->next == NULL) //Correct- 1 mark return 0; else printBack(node->next); //Correct - 1 mark cout << current-> element << " "; }
I am having a bit of difficulty with implementing an object oriented program that uses both linked lists and operator overloading. The program calls for adding and multiplying polynomials together, with each single polynomial being represented as a node of a linked list (which is further a data member of an object of a class I have defined to implement this program). For example:
polynomial A will be: 3x^4 // 1 node of a linked list polynomial B will be: 5x^2 // 1 node of a linked list polynomial C will be blank for the time being. // empty list
Now, I need to use operator overloading so that this following line of code can be implemented:
C = A + B;
C should now be: 3x^4 + 5x^2.
The checklist of which parts of my code that work:
constructor works; copy constructor works; destructor works; operator= works; print function needs work but i can worry about that later; operator* work on later
Here is my code:
#include <iostream> using namespace std; struct termNode { int exp; // exponent int coef; // coefficient termNode * next;
[Code] ....
For the time being I need to add multiple nodes together (with the result being in descending order). So for example:
polyType a(2,3), b(4,5), c(6,7), d; d = a + b + c; d.print(); // should print out 7x^6 + 5x^4 + 3x^2, but it will only print out: 3x^2 + 7x^6
For school we have to create a blackjack game using windows form. I had to store the images of each card into a sorted list so i created a class called cardList and created a constructor which contained the the sorted list called cards. So it looks kinda like this:
public class cardList : Form1 { SortedList cards = new SortedList(); public cardList()
[Code]....
There's probably a few other errors, I'm still trying to figure this whole c# thing out. why the error tells me (on the line that contains c.cards.GetByIndex(cardNumber);) that cards is inaccessible due the its protection level.
I am writing a class that dynamically allocates an array that holds a user-defined number of test scores (test scores go from 0 to 10 both included). Once all the test scores are entered and validated (values only between 0 and 10, both included), the array should be passed to a function that sorts them in ascending order. Another function should be called that calculates theaverage of all the scores.The main program should display the sorted list of scores and the average of the scores with appropriate headings.
I'm trying to write a function that takes two linked lists and creates a third one with only the common elements.
It assumes the first list (the caller) has no dups, but it doesn't seem to be working. The program doesn't crash, it just hangs when it is supposed to display L3 (the third list)..everything else runs and is displayed fine.
I have a linked list comprised of chars like so...
Code:
node1 - "p" node2 - "o" node3 - "p"
I need a function that will take in three perameters...node *replaceChar(node *head, char key, char *str)Stipulations of this function. head is the head of the list, 'key' and 'str' are guaranteed to contain alphanumeric characters only (A-Z, a-z, and 0-9). str can range from 1 to 1023 characters (inclusively). So if I call this function with these perameters..
Code:
node *head == /*the head of the list to be examined*/ char key == "p"char *str == "dog"The new list will look like this... node1 - 'd' node2 - 'o' node3 - 'g' node4 - 'o' node5 - 'd' node6 - 'o' node7 - 'g'
All instances of 'p' were replaced with 'dog' I have a toString function which takes in a string and converts it to a linked list and returns the head. So assume that you can call the function on str = "dog" so...
Code:
toString(str) == /*this will return the head to the list made from the str*/
If it's unclear what my question is...I am stumped on how to write the replaceChar function the one that takes in three perameters..
I am currently working on a program and Originally I was to create a bash program to extra information from youtube and create a table of users, views, titles, duration, etc. (I sent each to a txt file)..Then I was to create a C program to use the extracted information. In this case Users and read in the conents of user.txt and construct a linked list to hold the information. Then print from the Linked list.I managed to do that,
What I have to do now is start reading in The other files and construct a table. And radix sort it by views. But to get to the radix sort part I get stuck on reading in all the files correctly and having the linked list hold them. I keep getting seg faults when I change my code.
