C++ :: Compiler And Linker Errors For Linked List Class And Application
Aug 31, 2014
I am trying to write a program that will take a list of integers from a file and write them to another text file. I've been banging my head at this for days trying to get it to compile as it is riddled with linker and compiler errors.
We had to convert a single-line text editor which uses arrays to one that uses OOP and double-linked lists and I have been doing it in steps. I have, for the sake of convenience, put my headers, implementation and main all in one file.
I'm compiling this program in Hercules (the getch function uses C code).
I keep getting the error from the compiler saying "Undefined Symbol" for functions:
I've just started coding a "Mathematics" library for my own, just to practice some OOP concepts, but sadly I didn't get too far with it before the first errors appeared. That is, I created a Matrix.H and Matrix.CPP file (separate class) in a "Linear Algebra" folder.
However, when I run the code I get the following (linker?) error:
#include <iostream> #include "Matrix.h" using namespace std; int main() { Matrix<int> A(7,5); int row[] = {5, 10, 9, 11, -5};

I am using Visual Studio 2012 (stating this in case it could be related to the reason for which I get the error).
I have a project that is essentially a hot pot of C/asm (naked functions etc). The code gets injected into another EXE. It works fine when compiled in Visual C++ 6 but when compiled in Visual Studio 2008 it compiles fine but falls over in use.
Are there certain settings I need to look out for? I have optimization disabled and as far as I can tell the command line options for compiler/linker are the same (given the differences).
I have opened both builds in IDA and the 2008 build has more import and offset jumps are in different places.
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 use a SEH handler in my code, like this: __try { .. Some codes ... } __except( EXCEPTION_EXECUTE_HANDLER ) { TRACE(_T("Exception")); } but get the following compiler errors:

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{
my data structures and algorithms professor gave us the following assignment. We are to reimpliment a class we wrote earlier in semester called sequence(which holds a sequence of floats) using a linked list. However I am having trouble with the class's copy constructor and assignment operator, specifically when the sequence is not empty.

I am studying this sample code for linked list class node implementation. I am not 100% sure how this code keeps track of the head node. Here's what I know so far, and if you want to add/correct anything feel free to do so:
class Node { public: Node(); // constructor of class node without arguments Node(int, Node*); //constructor with arguments of int type and a pointer node type Node* next() const; void setNext(Node*); //member fun, returning a pointer of node type void setKey(int);
I am trying to implement a linked list using a class template, however each of my classes that I want in the list all inherit from an Account class. I have attempted to template the linked list class as account however Ive come into errors I can't resolve. How I can go about this?
The error exists within the customer.cpp class where it says
14IntelliSense: a value of type "Account *" cannot be assigned to an entity of type "CurrentAccount *"f:Further C++Assignment with TemplatesAssignmentCustomer.cpp229Assignment
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 have this piece of code from the book "Modern C++ Design" that checks for compile-time error. When i tried to compile it, i get the error "invalid application of size of to function type". How to make this compiler-time checker work?
i saved it with name PIYUSHAN.cpp.after compiling above program, it shows no errors, that means it get compiled successfully. but when I try to run this program it shows Linker error :
Undefined symbol add(int,int) in module PIYUSHAN.CPP Linker error : Undefined symbol sub(int,int) in module PIYUSHAN.CPP Linker error : Undefined symbol mul(int,int) in module PIYUSHAN.CPP Linker error : Undefined symbol div(int,int) in module PIYUSHAN.CPP
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>();

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 have an example where I have a variable belonging to a base class, but I would like to tell the compiler that it actually belongs to a derived class. How can I do this?
// base class: R0 // derived class: R1 // see function SetR1 for the problem class R0 { public: int a;
I'm a little confused by my programming assignment this week. I've been working at it Wednesday and I've made progress but I'm still confused as to how I'm supposed to do this. The class I made is called Stack, and it's derived from a template class called StackADT. We also utilize a class called unorderedLinkedList, which is derived from a class called linkedList.
We're supposed to implement all of the virtual functions from stackADT in the Stack class. The Stack data is stored in a an unorderedLinkedList, so what I'm confused by is how to implement a few of the Stack functions because there are no functions in unorderedLinkedList which we could call to manipulate the data.
As you can see from my attached code, I'm really confused by how I'm supposed to implement the pop() and top() functions, and I also think my initializeList() function is wrong. We don't have any similar functions in unorderedLinkedList to call, so I'm at a loss of how i'd access my unorderedLinkedList. My initial thought was to call the similar functions in the class that unorderedLinkedList was derived from, linkedList, but I'm unsure of this is what we're supposed to do, or if theres actually a way to access my unorderedLinkedList without having to use the functions from the base class.
NOTE: We're not allowed to modify stackADT, unorderedLinkedList, and linkedList.

I have been implementing a Hash Table class made, and ran into a bit of a problem in my Delete function. I have the hash table made up as
vector<list<HashNode<T,X>>> m_Table
My problem is when I iterate through the vector, and then the list in that current element to try and find the Node I want to delete, the STL list class gives me the error:
Error1error C2678: binary '==' : no operator found which takes a left-hand operand of type 'HashNode<T,X>' (or there is no acceptable conversion)
I have an issue. VS 2013 isn't recognizing objects that I've declared when I use class functions.I'm getting this error: "Line 14 and 15: Error C2228: left of '.asciiToFpc6' must have class/struct/union"...Here's the relevant code:
Additionally VS apparently doesn't like my bitwise operators in my class functions and doesn't think they're doing anything. It gives "warning C4552: ['|', '<<', '>>', '&'] : operator has no effect; expected operator with side-effect" for all of them, but it seems to me the code should work fine and actually accomplish things....
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 created a class called Point, in Point.h
I created a class called Rectangle in Rectangle.h and Rectangle.cpp
If I create an int main() function in Rectangle.cpp (that includes Rectangle.h), I can compile Rectangle.cpp and run the resulting program. Fine.
Question:
I create a separate file called main.cpp. I include Rectangle.h. But now the compiler complains.
Code: $ g++ main.cpp -o main /tmp/cc38JIph.o: In function `main': main.cpp:(.text+0x26): undefined reference to `Rectangle::Rectangle(int, int, int, int)' main.cpp:(.text+0x32): undefined reference to `Rectangle::getArea() const' collect2: ld returned 1 exit status If I can create a class in Point.h and use it in Rectangle.h, why can I not just use Rectangle in main.cpp?
And the files, of course:
file: main.cpp Code: #include <iostream> #include "Rectangle.h" using std::cout; using std::endl;
I have read the book over and over and I thought I understand "CLASS". But when I applied it and write the code the compiler tells me that there is a compiling error.
1. I have this method addProduct(Product* pProduct) in a Class called ProductRack, the code is in ProductRack.cpp file. The declaration of the Class methods and private variables are in ProductRack.h header file.
2. But when I call a method in the DeliveryCHute Class from the ProductRack Class I get a compiler errors which are these:
A.IntelliSense: a nonstatic member reference must be relative to a specific object B.error C2352: 'Project1::DeliveryChute::insertProduct' : illegal call of non-static member function
And this is causing the error:
if (Project1::DeliveryChute::insertProduct(pProduct) == false)
//THIS IS JUST ONE METHOD INSIDE ProductRack.cpp bool Project1::ProductRack::addProduct(Product* pProduct) { // Todo : Implementing if (Project1::DeliveryChute::insertProduct(pProduct) == false) return true;
