C++ :: Invalid Use Of Template Name ND Without Argument List

Dec 31, 2013

#ifndef BSTCLASS_H_

[Code]....

-'ND' is not a type; when I use it as a parameter
or
-invalid use of template name 'ND' without argument list; when I use it as a return type.

On some lines I try access the elements inside of 'ND' variables and I get errors saying that those elements don't exist for the given pointers.

C++ :: How To Remove Last Argument In Variadic Template

Nov 1, 2013

I wonder if it is possible to remove the last argument in an argument pack? Below is an example on what I want to accomplish:

template<template<int...> class A,int... Ints>
A<remove_last_int<Ints...>::list> func(const A<Ints...> & a0)
{
A<remove_last_int<Ints...>::list> a;
...
//Here a set the members of a based on a0.
...
return a;
}

For example, I want the return a A<1,2> value from (const A<1,2,3> & a0)

C++ :: Argument Deduction Of Function And Class Template

Jun 20, 2013

When we use a function template, we use a function template like a regular function, for example,

Code:
template<class T>
void foo(T t1, T t2)
{
}
foo(1,3);

Based on the arguments passed to foo, the compiler can deduct the type T. But on the other hand, when we use a class template, we always need to specify the type, for example,

Code:
template<class T>
struct sum {
static void foo(T t1, T t2)
{
}
};
sum<int>::foo(1,3);

Here we can't call sum::foo(1,3), otherwise we get compiler errors. My question is why the compiler can't deduct the type based on the arguments passed to foo? In addition, if we call function template foo like this,

Code:
foo(1, '3');

Then we get compiler errors. We need to specify the type like foo<int>(1.'3'). Since '3' can be always treated as integer, why we need to specify the type here?

C++ :: Write A Template That Accepts Argument And Returns Its Absolute Value

Nov 19, 2014

Write a template that accepts an argument and returns its absolute value. The absolute entered by the user, then return the total. The argument sent into the function should be the number of values the function is to read. Test the template in a simple driver program that sends values of various types as arguments and displays the results.

#include <iostream>
using namespace std;
template <class integertemplate>
integertemplate totalint (integertemplate integers) {
cout << "How many integer values do you wish to total? ";
cin >> integers;

C++ :: Passing A Function Pointer As Template Argument To A Class

Aug 15, 2012

I have in the past written code for templated functions where one function argument can be either a function pointer or a Functor. Works pretty straightforward.

Now I am in a situation where I am actually trying to pass a function pointer as template argument to a class. Unfortunately this does not work, I can pass the Functor class but not the function pointer. Below code illustrates the issue:

Code:
#include <string>
#include <iostream>
#include <sstream>
#include <cstdlib>
// For demonstration
const char * external_library_call() {
return "FFFF";

[Code] .....

The idea is to have the definition of the Record class simple and readable and have a maintainable way to add auto-conversion functions to the class. So the lines I commented out are the desirable way how I want my code to look. Unfortunately I could not come up with any way that was close to readable for solving this.

C :: Modifying Linked List - Passing Pointer As Argument

Feb 27, 2015

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:

Code:
typedef struct PCB{
int id;
struct PCB *next;
struct PCB *prev;
}PCB_rec, *PCB_p;

Here is my function to delete the last node (given the pointer is pointing at the last node of the list):

Code:
void del_last_node(PCB_p *process_list){
PCB_p temp = process_list;
if (temp->prev != NULL){
temp = temp->prev;

[Code] ....

And here is how I called the function:

Code: del_last_node(&process_list);

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

C :: Exponent Program - Expression Evaluates To A Function Which Is Missing Argument List

I am new to C programming and I am trying to compile and run an exponent program my instructor posted for us but it is giving me an error saying:

Warning c4550: expression evaluates to a function which is missing an argument list.

Why this is happening (she doesn't seem to find anything wrong with the code). From what I could gather there is some issue with the math but idk. It is supposed to prompt for the number and the exponent to raise it to, then calculate and output the result.

C++ :: File IO Inside A Class - No Instance Of Overloaded Function Getline Matches Argument List

Jan 24, 2012

Hey I am trying to use the getline() function to read a line from a file. For some reason Visual Studio 2010 gives me the following error. "No instance of overloaded function "getline" matches the argument list". The piece of code that produces the error is in a class in a separate .h file and is executed as a method of the object. I'm almost certain it has something to do with either the compiler thinking I am calling another getline in a different namespace or my parameters for the function are incorrect. Here is the code:

C++ :: Trying To Add Template Class To Maintain List

May 12, 2013

I wrote this menu-driven program that maintains a list of restaurants. The program runs fine as it is right now, but my problem is I need to create a new array template class to maintain the list of restaurants, and when a new restaurant is added it must be created dynamically.

I'm having a hard time figuring out what exactly I need to do for this. Templates confuse me allot and I've read all the sections on templates here and in my book, but i'm still lost. The dynamic memory part is throwing me off as well.

main.pp

#include <iostream>
#include <string>
#include <iomanip>
#include "Restaurant.h"

Restaurant.h

#pragma once
#include <iostream>
#include <string>
#include "FTime.h"

C/C++ :: Linked List Template Search

Feb 6, 2015

I have a linklist program I've written that seems to work just fine at least, it outputs the right information. However when it comes to the end and says press any key to continue, it crashes when I press a key says debug assertion error rather than just exiting. I haven't gone back and put in comments yet, I know I need to get used to commenting as I go />/>

#ifndef LIST_H
#define LIST_H
#include <iostream>
#include <cstdlib>
using namespace std;
template <class T>
class LinkList {

[Code] ....

Another bit of information. It was working without crashing when I only had the intlist functions called. When I added the doublelist is when I began getting the error however now if I remove the doubelist and go back to just having the intlist calls it still gives the error.

C++ :: Removing Element From Template Linked List?

Nov 11, 2013

I have been trying to implement a way to remove a post from a list of posts implemented with a template doubly linked list. I have thought that the best way to do this might by operator overloading, but I have digressed. I have just thought of using a isEqual that checks equality, but when trying to implement i'm getting weird errors.

This is within my class wall, which is a linked list of wall posts, getPostInfo is within the class WallPost.

bool isEqual(WallPost const & a, WallPost const & b)
{
if(a.getPostInfo() == b.getPostInfo())
return true;
else
return false;
}

I have several instances of the error "void illegal with all types" on line 3. It also is complaining about a not being a arithmetic, unscoped enum, or pointer type. I am assuming that it is because my getPostInfo function is a void.

C/C++ :: Error C2512 With Template Linked List?

Oct 29, 2013

I have made a Template Class that I named ArrayList(to coincide with ArrayLists in Java)and it works for the primitive types string, int, double, etc.; however, when I try making the ArrayList with a class object instead of a primitive type it gives:

"error C2512: 'ArrayList<Missile>::listCell' : no appropriate default constructor available"

And I am not sure why. My ArrayList Class is defined by:

template <class type> class ArrayList{  
    struct listCell{
        type dataStorage;
        listCell *next = nullptr;

[Code] ....

The error takes place in the add method of the ArrayList class:

void add(type toAdd){
        size++;  
        if (head == nullptr){
            head = new listCell();
            head->dataStorage = toAdd;

[Code] .... 

only when I use a class object instead of a primitive storage type.

The class "Missile" has been defined and compiles successfully, and the code calling the add method is here:

    ArrayList<Missile> missiles;
    Missile *missile;  
//Constructor and Deconstructor not shown  
    void fire(){
        missile = new Missile(xPos, yPos, true);
        missiles.add((*missile));
    }  

why this causes an error?

C++ :: Linked List Node Passed As Parameter / Argument Pointer To Pointer Notation

Jan 17, 2014

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

bool deleteNode(struct node *head, struct node *delptr)

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);

#include "stdafx.h"
#include<iostream>
