I'm trying to make a function that lets me pass an index and a string and will insert the string at that index in the linkedlist... here is so function i have so far:
Code:
typedef struct node {
char* value;
struct node* next;
} LinkedList;
void llAddAtIndex(LinkedList** ll, char* value, int index) {

I'm still trying to insert a node at a passed index in a linked list. This is my function, it doesn't work but i feel like it's close.
Code:
void llAddAtIndex(LinkedList** ll, char* value, int index) {
LinkedList* newNode = (LinkedList*)malloc(sizeof(LinkedList));
newNode->value = value;
LinkedList* prevNode = *ll;
for(int i = 0; i < index; i++){

I have a program and function i'm having an issue understanding. Here is what it's doing in the main.
int main() {
orderedLinkedList<MemberDO> memberList;
MemberDO::readFromFile("Member.dat", memberList);
return 0;
}
So it is creating a linked list object using the MemberDO class type which has a int, string, char and double. Then it will call the readFromFile static function in the MemberDO. So this is where my problem is I have this function
void MemberDO::readFromFile(char *fname, orderedLinkedList<MemberDO>& list) {
}
How do I read in each individual data member from the input then create a new MemberDO object and insert the objects into the linked list specified in the second argument list?
Here is the MemberDO class declarations
class MemberDO {
private:
int key;
string lastName;
char firstInitial;
double dues;

I'm having trouble inserting a node in a nth position into a double linked list. My for loop is giving me an exception handler error and I can't link the node after the new node is inserted back to the new node. Here is my code,
void mylist::insertpos(const int &pos, const string &s, const int & c) {
listnode* temp1 = new listnode(s,c);
temp1->s =s;
temp1->next = NULL;

I attached my header file incase you need to see the definitions for my objects.
It is suppose to insert items in Linked List in sorted ascending order and no duplicates are allowed.The code complies but it creates duplicates out of order.
ListRetVal CSortedList :: InsertItem(const ListItemType &newItem)
{
ListItemNode* newLNode = new ListItemNode();
newLNode->value=newItem;
newLNode->next=NULL;

How to randomly insert certain numbers into a linked list with 10 nodes. Meaning I want to put for example numbers 1 5 10 15 20 25 30 35 40 50 in random locations in the linked list.
View 1 Replies View Relatedis this correct? I used this sorting with numbers i don't know if it is the same with strings. When I run it, there are no errors detected, but when i try to view it, the inputs does not appear.
void add(node **h, node **t){
node *temp, *ptr;
char s[20];
temp = (node*) malloc(sizeof(node));

printf("Fruit: ");
scanf("%s", temp->fruit);

I'm trying to figure out how to insert a node into a linked list at a particular location based on a time..I have this declared outside of everything globally.
Code:
struct aTime {
char name[LENGTH];
int time;
struct aTime* next;
};
struct aTime* head = NULL; And then this function that is used to add nodes (aTime structs) to a linked list. It adds the first node fine, but not subsequent ones. I think this is because I have while p-> != NULL but it is always going to be null when the function is called since I create a new aTime struct. So I guess my question is how, after one struct has been added at the beginning, do I point to the head node and traverse the list, insert a node, and make sure everything is still linked? Do I need another temp aTime struct?
Code:
void add_time(char name[LENGTH], int seconds)
{
struct aTime *p;
p = (struct aTime *) malloc(sizeof(struct aTime));
if (head == NULL)
{
strcpy(p->name, name);
p->seconds = seconds;
}

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 storing info in a vector but I want to store certain info at a particular index. I am new to using vectors and am unsure about have to do this. I am aware of the insert method but am confused on how to use it to store at a particular index.

I am creating a to-do list application and to store the tasks on the list, I am trying to create a linked list. the code for it so far is as follows:
public class Node //Class for nodes which make up a linked list {
//Declaring the data to be stored in each node and next variable to point to the next node
public string title;
public string description;
public string priority;
public string finish;
public string complete;
[Code] ....
The problem with this arises when I try to create a new node from another class like so:
createForm create = new createForm(); //Creates an object reference to createForm
create.ShowDialog(); //Shows the createTask form for creating a new task
//Declares variables and stores the return value of methods in createForm
string _title = create.getTitle;
[Code] ....
The variables _title etc.. all store values from text boxes as string. However, the code creating the object says the the variables cannot be implicitly converted from type 'string' to 'int'. Why this error is happening??
why strcmp() doesn't return true when comparing a string constant with a string that was acquired via a linked list. By the way, the data in the linked list was taken from a text file. Does that imply that there's a new line () character in the string from the linked list?
Code:
struct Node{
char ACNO[15];
struct Node *next;
[Code]....
My program takes in an input file from the command line and converts the string from the file into a linked list and then depending on the command it will manipulate the string to either reverse the list, print the list, or take a character out...I'm having trouble taking a character out, my code compiles fine but doesn't change the string at all
Code:
#include <stdio.h>
#include <stdlib.h>
#define SIZE 1024

I'm new to strings. I want to know how to insert a string right in the middle of another string.Is it possible to do that? for example my first random word is 12345678 and the 2nd random word is jimmy I would have to write .
This in my code uno.insert(4,dos); for jimmy to be printed in the middle of the first string,but what if my 1st random word is has more than 8 characters what would I do in that case?
Code:
cout << "type random word" << endl;
getline (cin , uno);
//greatavenue
cout <<"enter random word#2"<<endl;
getline (cin , dos);
//_coconut_
uno.insert(5,dos);
cout<<uno<<endl;
//great_coconut_avenue
im using a for loop to find the index values of the tied high scores and store them into string list then reference list in the second for loop to output it to screen however it isnt letting me use an array with index i as an index its self.
void printHighest(Student s[], int length){
int index;
string list[10];//you're never going to have more than 10 people with a tieing highscore.
index = findMax(s, length);
[Code] ....
For the time being I simply removed the idea of string list and just put the contents of the second for loop into the if statement above it. However, I am still curious as to if I can reference an index of an array in an index of another array.
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.
template <typename T>
LList <T> LList <T>:: common (LList <T> &B)//common fct

Let's say i have a string "file.txt" and i want to insert "_out" to make it look like "file_out.txt"
I don't know how to do this ....
I would like to insert some character after each number of my string .. I found how to insert before each character, but what I want is :
string str = "12 + 5"
insert ^ after each number
Output = "12^ + 5^"
Code:
// 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.)
#include <stdio.h
struct entry1 {
int value;
struct entry1 *next;
};
[code]...
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've been typed out a C program to let the user define the size of their string , and key in characters for this string , the program would then prompt the user for a character to search for in the string and return it's index value. Eg. Index of c in abc is 2. My code is as shown:
#include<stdio.h>
#define SIZE 20
int search(char x[SIZE+1] , int n , char s);
int main(void){
char x[SIZE+1] , s;
int n , index;
[Code] ....
However , after I key in my characters for the string , the program does not prompt me to input a character to look for, it just prints it out and returns some funny number. But the program works just fine is I move this portion to the top :
printf("Enter alphabet to find: ");
scanf("%c",&s);
