C/C++ :: Creating Singly Linked List / Loading Class Type Array
Aug 6, 2014
I've written this class and struct to create a singly linked list. The data is stored in the binary file which I've opened and read. I'm trying to load said data into a class type array. The errors I'm getting are "incompatible types in assignment of 'StatehoodInfo' to char[3]" Lines 130-134 is what I was working on.
I am having difficulty getting my program to run. I have looked and looked many times trying to figure out what I am doing wrong. I have a hunch that it's my load function that's acting up, but from my perspective, my creation of my singly linked list looks good. From the creation of my singly linked list, does anything stand out as being abnormal?
I was trying to write a function in C to delete a node(only from the middle) from a Singly Linked List. I wrote one but not sure if the code will work fine under all test conditions. I have tested it and shows no error so far.
Code: void deleteAt(struct node *root, int number){ while(root->link != NULL) { if(root->link->item == number) //checks if the next node is the element to be deleted { root->link = root->link->link; //points the link of the element to be deleted to the element before the element to be deleted } else root = root->link; } }
Well, basically, what I've been doing was creating a class that would implement the concept of Double Linked List, but that would behave like a queue ( the STL implementation is deque, or Double Ended Queue ).
The problem occured when I have been trying to generalize the class using templates. I mean, why use only integers ? Why not double or char or what not ?
Worked perfectly before including all the template stuff..
// Source.cpp <=> Main.cpp #include <iostream> #include "DList.h" using namespace std; int main(void) { DList<int> *list; list = new DList<int>();
[Code] .....
The errors returned by the compiler:
Error1error C2955: 'Node' : use of class template requires template argument listc:usersjumperdesktopc++ otherdouble linked listdouble linked listdlist.h6 Error2error C2955: 'Node' : use of class template requires template argument listc:usersjumperdesktopc++ otherdouble linked listdouble linked listdlist.h6
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.
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 am working on a program that is supposed to eventually be able to evaluate bridge hands, but one of the first things I need to do is create and load an array. The program is supposed to read in hands from a file (each line in the file is a hand of 13 cards), evaluate these hands based on a list of rules, and display the results.
Here is the file that will be used for the program:
2C QD TC AD 6C 3D TD 3H 5H 7H AS JH KH 3C 4C 2D AC QC 7S 7C TD 9C 4D KS 8D 6C 2C 3C KC JC 4C 8C 7C QC AC 5C 9C 6C TC 5H 3S 4D KC 9S 3D 4S 8H JC TC 8S 2S 4C 2S 5D 6S 8S 9D 3C 2H TH 2H 6D %S 8S 7S 4D 3H 4S KS QH JH 5C 9S 2C QD TC AD 6C 3D TD 3C 5H 7H AS JH KD QS 2C QD TC AD 6C 3D TD 2C 5D 7H AS JH KD 2H 6D TS 8Z 7S 4D 3H 4S KS QD JH 5C 9S
I've gone through and wrote out what the program is supposed to do and what I think is needed and what steps to take to accomplish this, but am getting stuck on the array. If you can't tell I'm extremely new to this and am still learning. I'm not sure how to create and load an array like this since it seems to me there'd be two elements per index, a suit and a value.
Also, the instructions mention that I will need a data structure to hold the cards in an ordered manner. I'm really confused on this as well, if I'm using an array, how does the data structure come into play?
Can the data structure be used in place of the array?
Here is the code I have so far, but keep in mind that at the moment all it actually does is open the file (The "File is open" message will be taken out as the code progresses, I just threw that in there to make sure the file was actually being opened):
//#include <program3.h> #include <iostream> #include <string> #include <fstream> using namespace std; int main() { char handsArray[]; ifstream bridgeFile;
[code]....
The input should be sorted by suit and the rank within the suit and be displayed in teh following format:
Clubs 10 6 2 Diamonds A Q 10 3 Hearts K J 7 5 3 Spades A Points = 16
I am creating linked list of memory blocks. Allocate a block of 512 bytes and insert into the first node of list. then Allocate a 2nd block of same size and add to the list. now free each block from the list.
How would I go about creating a tree like structure using linked lists, I am thinking of making a rubix cube solver program, what I want to do create nodes that each do one operation like turn left, right, up, down but I dont know how to go about starting this.
I need to create a templated doubly linked list, with an iterator class within the list class. This program is to function just like the STL list class but I only need to implement functions that I am using, My trouble is I am kind of clueless on the iterator part and the fact that the list is templated is giving me syntax grief. I have pasted the code I have done so far.
1. On the syntax implementing the list and iterator functions outside of the class 2. I am not sure when to deference the iterator in the functions, but think I have it right so far 3. For the reverse function can I copy the list into a new list in reverse then re add them to the original list overwriting the same values? I have the code I have so far there 4. For the iterator erase function, I am not sure if I am deleting the node correctly. 5. I am not sure if I need template <typename T> above the iterator functions. Does the iterator class need to be a template? Right now it is not.
// Templated doubly linked list class
#include <iostream> using namespace std; template <typename T> class list { private: Node *head; Node *tail;
In the program I'm writing, I'm creating a linked list of students with individual data read from a file. At the moment, I have written two functions to accomplish this; one that creates a student node and fills it from a line file, and a second that calls on the first to create a linked list. It seems to work fine except for one thing; It seems that EOF is being reached first, but the function continues on anyways? Here is my code so far...
I've written code for a selection sort algorithm to sort through a singly linked list, However, it only brings the smallest node to the front, but doesnt swap positions of any of the remaining nodes, even though they are not in order.
I am trying to write a generic linked list in c, but for some reason i keep getting errors saying "incompatible pointer type. This is the code and erros:
I am trying to use a class Student and declare it as a list type. I can pushback but without changing the List.h or Node.h how can I print the data in list2?
I'm trying to develop a program that stores a list of hw assignments in the form of "Date,Assignment name,grade". I have functions that add,remove, and delete from a list, but I would also like to search and delete a particular date found in the list. From here, split - Splitting a string in C++ - Stack Overflow I've tested Evan Teran's method to split a string, but I'm unsure of how to implement it in my code.
List.h Code: #ifndef LIST_H #define LIST_H #include <string> using namespace std; class List{
