问题 In linked list implementation, the insertion of a new node to the linked list is usually written like this: void push(struct node** head_ref, int new_data) /* 1. allocate node */ struct node* new_node = (struct node*) malloc(sizeof(struct node)); /* 2. put in the data */ new_node->data = new_data; /* 3. Make next of new node as head */ new_node->next = (*head_ref); /* 4. move the head to point to the new node */ (*head_ref) = new_node; (I took this code from http://quiz.geeksforgeeks.org

问题 My program crashes under a certain instance/case, it complies and runs fine otherwise. We were given a text file formatted like so: 12 JackSprat 2 1 65000 13 HumptyDumpty 5 3 30000 17 BoPeep 2 3 30000 20 BoyBlue 3 2 58000 0 we are required to read from file and store into a struct using a linked list. so far my code looks like this: #include <stdio.h> #include <stdlib.h> #include <string.h> #define NAME_LENGTH 20 typedef struct employeeData { int EMP_ID; char* Name; int Dept; int Rank; double

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . i received great help on my other questions in relation to this link list problem. My current problem is now that the head of the list remains null so i cannot actually link any nodes to it or print anything out to the console. The problem is the insert_node function, so when print is called the while loop doesn

问题 I am having trouble with my insert to the front of the linked list fucntion in C #define arrSIZE = 100; struct listNode { char data[arrSIZE]; struct listNode *nextPtr; }; typedef struct listNode ListNode; void insertHead(ListNode *sPtr, char value[arrSIZE]){ ListNode *newPtr = (ListNode *)malloc(sizeof(ListNode)); strncpy(newPtr->data, value, arrSIZE); if(sPtr ==NULL){ newPtr->nextPtr=NULL; sPtr = newPtr; }else{ newPtr->nextPtr=sPtr; sPtr =newPtr; } } 回答1: I can see why. -You're setting sPtr,

问题 Been a while since I used java. I want to use Java's built in linkedlist class but I want a custom node class that has children and siblings. How can I write a custom node class that Java's linked list will use? Just a matter of creating the node class and declaring a linkedlist class but just create a new constructor that will override javas? Thanks! 回答1: LinkedList uses a private Node<E> class internally. If this is just an academic exercise, given that the source code is available you

问题 an adress of a new list of the odd elements removed. I find this task quite complicated, and I would be happy if you could help to repair or improve my code. Here is what I've done by far: typedef struct list{ int data; struct list* next; } List; List* removeOddValues(List** source) { List* curr= *source; List* prev; List* odd= NULL; while (curr) { if ((curr->data)%2==1) //odd// { insertNodeToEnd(&odd, curr->data); //creating a new list of those odd elements// prev->next = curr->next; } else

问题 I'm trying to create a program that gets string input from a text file, inserting the content into a list, word by word. I also have to calculate the numbers of the duplicates. My program works fine for the small input text file (1 line of string). But whenever I feed it with a bigger text file, it crashes. Any help will be great. Here is my code: #include <iostream> #include <fstream> #include <sstream> using namespace std; class Bag { private: struct BagNode { string dataValue; int
