C++ :: Linked List Set Function - Forbids Comparison Between Pointer And Integer
May 5, 2014
I'm trying to write a function called 'set' that sets the value of the i'th cell to val on my linkedList, and then returns the previous contents. I am stuck on it due to compiling errors:
template <typename T>
T set(Node<T> *head, int i, const T &val) {
for(int n = 0; n < i; n++)
if(head == val) {
val = i;
} return val;
} #endif
When I try to call it in the main() I get these errors:
node_utils.h: In function ‘T set(Node<T>*, int, const T&) [with T = int]’:
node_demo.cpp:26:38: instantiated from here
node_utils.h:161:2: error: ISO C++ forbids comparison between pointer and integer [-fpermissive]
node_utils.h:162:3: error: assignment of read-only reference ‘val’
So, I understand that I can't compare head & val on my if-statement -- But what do I do?
I think I am doing it right but im getting a couple of errors that i cant fix ...
#include <iostream> using namespace std; int main(){ int x [8] [8], r, c; for(c = 0; c <= 8; c++){ cout << " Enter a number from 1 to 7 " << endl;
[Code] .....
these are the errors :
assignment15_meem.cpp: In function âint main()â: assignment15_meem.cpp:7: error: no match for âoperator>>â in âstd::cin >> x[c]â assignment15_meem.cpp:10: error: ISO C++ forbids comparison between pointer and integer
This is some code that simulates files and directories the same way an operating system does so. I commented out every std::string occurrence because I got the :
terminate called after throwing an instance of 'std::length_error' what(): basic_string::_S_create
I was having problems changing the value of my head node I passed it as an argument as head which would be the address. The parameter was defined as struct node *head. like this
I tried manipultaing pointer values to change head node value but it did not work. I saw some code online which used pointer to pointers(in code below) to change head node value it worked I dont fully understand why. Would like better understanding of why.
Would also like to know why the argument call needed &head instead of just head.
remove = deleteNode(&head,found); opposed to remove = deleteNode(head,found);
I've been playing around with making a linked list in C and am having trouble adding to the beginning of the list. For the add_beg() function: the statement "head = newNode" only works locally. This leads me to believe this is a pointer problem. However, the add_end() function works correctly. Ideally, I would like to print "0 1 2 3 4" after using the add_end(root, 0). Currently, print only gives me "1 2 3 4".
#include <stdio.h> #include <stdlib.h> //Create a node struct typedef struct node { //data int val;
I'm having a bit of an issue here. I have a linked list where each node contains a pointer to a string (which has been malloc'd when the node was created and inserted) and a pointer to the next node in the linked list.
I'm creating a function which will free the node (or effectively delete it). However, I'm receiving a free(): invalid pointer error.
I am having trouble modifying a linked list. I am writing a function to delete the last node from the linked list, but it gave me incompatible types error.Here is my struct:
It gives me the following errors: initialization from incompatible pointer type at line: PCB_p temp = process_list assignment from incompatible pointer type at line: process_list = temp
I am getting and infinite loop for loop pointer variable current which points to head and is incremented by current->next in while loop. I use the pointer variable the same way in my display routine and it works. Here is listing of code.
#include "stdafx.h" #include<iostream> struct node{ int data; node *next;
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:
The log file gives me: In function ‘memFileAlloc’ assignment makes pointer from integer without a cast..When compiling the drivers for the Matrox card in the DL580. The offending code is:
Here are the errors: no matches converting function `concat' to type `class Dlist (*)(class List<int>, class List<int>)' error candidates are: template<class T> Dlist concat(Dlist, Dlist)
no matching function for call to `concat(Dlist&, Dlist&)'
I can't understand what the compiler is trying to tell me.
I'm trying to create a function that allows insertion anywhere in a linked list...here is what I have so far but am a bit confused on where to go from here
I'm writing a linked list program for class that has a simple text based menu and I believe I am nearly done, it just wont recognize my "count" function as a function and I don't know why. The error comes up at line 70.
I have a linkedList search function given and I am having a little trouble getting it to work. I've made a few attempts with no success. Given normal search code:
template <class Type> bool orderedLinkedList<Type>::search(const Type& searchItem) const { bool found = false; nodeType<Type> *current; //pointer to traverse the list
current = first; //start the search at the first node
[Code] .....
My attempt to make it a recursive search:
template <class Type> bool orderedLinkedList<Type>::search(const Type& searchItem) const { //bool found = false; nodeType<Type> *current; //pointer to traverse the list current = first; //start the search at the first node
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.
I'm have troubles with this program that requires me to make a search through a Linked List and find a specified value. It also needs to be a template function. I've completed the rest of the program fine and everything runs ok except for the search function. Code below:
The program I have below. If you copy and paste it it should work. However, When I uncomment my search function I get lots of errors and I think it has to do with incorrect syntax of it being a template. Need to do this search function:
Linked.h header file
Code: #ifndef LINKED_H #define LINKED_H #include<iostream> template <class T> class Linked { private: // Declare a structure for the list
i am having trouble figuring out inorder traversal in this assignment. I was given this function definition in the homework i have to declare it. The problem i am having is how to use pointer to function to traverse the list.
void CBSTree<NodeType>::InOrderTraversal(void (*fPtr)(const NodeType&)) const; void CBSTree<NodeType>::InOrder(const CTreeNode<NodeType> *const nodePtr ,void (*fPtr)(const NodeType&)) const; //nodePtr is a pointer to a NodeType object (this is a recursive function, initially this points to the root). //fPtr is a pointer to a non-member function that takes a const reference to a NodeType object as input, and //returns nothing
I know without the pointer to function parameter it will be like this.
It fills the singly-linked list with 0 through 9 and calls a function to prompt the user to search for a number. I don't see any glaring errors, I was just wondering what could be done to simplify it or if there's anything I missed.
I am trying to write a function to return the first element of a link list queue. I am not real sure how to implement this. I have include a copy of the struct for my Node & queue.
