C/C++ :: Creating Singly Linked List / Loading Class Type Array

Aug 6, 2014

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.

#include <iostream>
#include <iomanip>
#include <fstream>

C++ :: Linked List To Store Student ID And GPA

Apr 2, 2014

So I have to store a student Id and gpa and name in a linked list. I keep getting error messages.

Like: lab 20.cpp(43): error C2628: 'Student' followed by 'int' is illegal (did you forget a ';'?)
(43): error C3874: return type of 'main' should be 'int' instead of 'Student'
(71): error C2664: 'Student::Student(const Student &)' : cannot convert parameter 1 from 'int' to 'const Student &'
Reason: cannot convert from 'int' to 'const Student'
No constructor could take the source type, or constructor overload resolution was ambiguous

#include <stdio.h>
#include <stdlib.h>
#include <iostream>
#include <string>
using namespace std;
struct Student {
string name;
double gpa;

C :: Linked List To Gather Student Info

Dec 17, 2014

The programme has to be a linked list to gather student info, (ie name, lastname, student no, and three grade); the first and last name must use malloc correctly, there must be an insert and delete function and a printfunction. and they must print out in alphabetical order.

Code:
#include #include #include struct student{
char *lastName;
char *firstName;
char dob[20];
char sID[20];

C/C++ :: Maintain Student Academic Records Using Linked List

Sep 16, 2014

Assignment on Linked List : Write a program that maintains student academic records using a linked list. The data structure is to be implemented as an array of structures. The fields of the structure are as follows:

• Student ID - this should be unique

• Last name

• First name

• Middle initial

• Course

• QPA

• Address

The program shall be menu driven. This means that the actions that the user can do with the program is govern by choosing an option. The menu shall look like this:

Student Records

1. Add student Academic Record

2. Edit student first name

3. Delete student record

4. View student record (by last name)

5. View all student records

6. Exit

For the edit and delete, the search value should be the student ID. What's lacking on my codes is for the 3rd option. What should I must do with it? These are my codes

#include<stdio.h>
#include<conio.h>
#include<string.h>
#include<stdlib.h>
#define M 10
#define FLUSH while(getchar() != '')

C++ :: Declare Template Type Object Inside Template Type Class Definition

Oct 12, 2013

Let me put it into the code snippet:

/**
This class build the singleton design pattern.
Here you have full control over construction and deconstruction of the object.
*/
template<class T>
class Singleton

[Code]....

I am getting error at the assertion points when i call to the class as follows:

osgOpenCL::Context *cxt = osgOpenCL::Singleton<osgOpenCL::Context>::getPtr();

I tried commenting assertion statements and then the debugger just exits at the point where getPtr() is called.

C++ :: Passing Class As Type In Template Class

Nov 30, 2013

I am trying to pass a class as a type to a template class. This class's constructor needs an argument but I cannot find the correct syntax. Is it possible?

Here is an example of what I described above. I did not compiled it, it is for illustrative purpose only. And of course argument val of the myData constructor would be doing something more useful than simply initializing an int....

template <class T>
class templateClass {
templateClass() {};

[Code]....

My real code would only compile is I add the myData constructor:

myData () {};

and gdb confirmed that it is this constructor that get called, even with dummy(4).

C++ ::  Getting Error With List Of Key Type

Oct 26, 2014

I have a Polymorphic class and some child classes, of which I need to make multiple instances of, using a list container. I've set the key type to be a unique pointer of the polymorphic class, and the values of each element pointing to a New Child instance, like so:

std::list<std::unique_ptr<Polymorphic>> polymorphic;
polymorphic.push_back(new Child(foo, bar));

The only problem is that when I try to push_back a new element, I get a compiler error, saying "No instance of overloaded function".Should I try and create a pointer object on it's own and push back that object as an element, it will work fine:

std::unique_ptr<Polymorphic> polym(new Child(foo, bar));
std::list<std::unique_ptr<Polymorphic>> polymorphic;
polymorphic.push_back(polym);

Is there some way I can push a new Child instead of having to create a Polymorphic pointer object and pushing that?

C# :: Convert Anonymous Type List Into Bindinglist?

Sep 26, 2014

So I query out data from multiple tables and I put it as anonymous type. But since I need to get the remove function going, my datagridview has to get datasource from a bindinglist, not just a list. What could I do from this situation? I already checked: [URL] but intellisense doesn't pick up the .ToBindingList() function for my query.

C++ :: Can Use Templates To Make A Multi-type Linked List?

Apr 28, 2014

If I wanted an int connected to a float connected to a string connected to a POD, would all I have to do is :

Code:

template<class T, class X>
struct node {
T data;
node<X> *next;
};

Or would I be forced into using polymorphism?

C :: Change / Fill List Without Changing Function Type

I am an IT student currently learning linked list. I have a problem with my code here. After I call addFront() my list doesn't change when I display it. How do I somewhat change/fill my list without changing the function type? I know it works on pointers still messed up with linked list.

C++ :: Expression Must Have A Class Type?

Apr 3, 2014

I am making a program that allows you to add two big numbers that are larger then what int can handle together. I think I have done everything to accomplish this but when I try to instantiate the program I get a error Expression must have a class type.

Here is my main file that is supposed to instantiate the program.

Code: #include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>

C++ :: Return Value For A Type Class?

Code:
returnType operatorOperatorSymbol (parameterList); // syntax for operator overloading
Class Fraction

public:
Fraction operator-(const Fraction& f1){

Is this even syntactically correct? It gives me errors. Im just trying to compile it without errors. I think the function makes sense since its returning a type Class

C++ :: Define A Class For A Type

Apr 29, 2014

Define a class for a type called CounterType. An object of this type is used to count things, so it records a count that is a non-negative whole number.

Include a mutator function that sets the counter to a count given as an argument. Include member functions to increase the count by one and to decrease the count by one. Be sure that no member function allows the value of the counter to become negative.Also, include a member function that returns the current count value and one that outputs the count. Embed your class definition in a test program and run sufficient tests to verify it all works correctly.

C++ :: Error / Expression Must Have A Class Type

Apr 15, 2015

I'm trying to learn recursion, and I'm using a simple array to experiment with it, but I have a couple of annoying errors that I don't understand why they're there. Here's the code:

Code:
#include <cstdlib>
#include <iostream>
using namespace std;
int largest(const int arr[], int lowerIndex, int upperIndex) {
int max;

[code]....

Now try to print the array backwards:

//Use a recursive algorithm to find the largest element in arr:
int largest(arr[], lowerIndex, upperIndex);//error: expected an expression

C++ :: Initializing Array Of String Type In A Class

Apr 28, 2013

I want to use this array as part of my class. I have tried several different angles trying to get it to work but with out success. I have been checking to see if it works by simply using "cout << dayName[3];" It is printing nothing at all. What is the proper way to initialize this array of strings?

First I tried this:
const string dayName[] = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"};

then I tried this:
const string dayName[7];
dayName[0] = "Sunday";
dayName[1] = "Monday";
dayName[2] ="Tuesday";
dayName[3] ="Wednesday";
dayName[4] ="Thursday";
dayName[5] ="Friday";
dayName[6] ="Saturday";

My implemetation file code and my header file code is here (header first):

//dayType.h, the specification file for the class dayType
#include <iostream>
#include <string>
using namespace std;
class dayType{
