C++ :: Program To Save List Of Items With Associated Attributes
Nov 22, 2012
I'm supposed to write a program that is able to save a list of items such as books, CDs, or DVDs. The items that are saved must have attributes associated with them. For example a book has a title, author, publisher, and ISBN.
I'm supposed to create a program that is able to save the database of items to a file on the hard drive and also retrieve it from the hard drive.
The user should be able to
1. Enter items
2. Display a list of the items
3. Save the list to disk
4. Read the list from disk
5. Sort the list
6. Exit the program
I know I should use arrays and structs but I don't where to start.

I wrote this program to create a list of medical resources and their attributes, a task I have been performing repeatedly lately. I'm still fairly new to C++, so I thought to create a structure "Resource", and then an array of those structures "city[300]". My problem is that the input doesn't seem to be happening: the program runs, but when it prints to screen/writes to the file at the end, all the shows is:
Resource Type:
Name:
Address:
Phone:
Website:
for every resource that was input. All the fields are blank.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
struct Resource {
string typeID;
string name;

I'm trying to run so called student-administration program.I got functions that can read and write student data, but the one saving the data from about 30 students has some problem that I can't figure. (warning: I'm quite new to C programming)so this is the code:..I guess I can't use global variables as function arguments?
Code:
//global variables
static char ReturnName[31];
static char ReturnFirstName[31];
static float ReturnAverage;
}
[code]....
incompatible types when assigning to type 'char[31]' from type 'int'

I am trying to develop a GUI using MFC, but I am having trouble using CFiledialog to save a file. The problem is, the file is not getting saved to the folder when I use the CFiledialog. Below is the code I am using.
Code:
CString szFilter = "XNRep Files (*.xnrep)|*.xnrep||";
CString s = "xnrep";
CString t = "";
CFileDialog fileDlg(FALSE, s, t, NULL, szFilter);
if(fileDlg.DoModal() == IDOK)
{
std::ofstream file;
[Code]....
After the file dialog opens up, I enter the name of the file and select OK button. But the file does not show up in the directory I am saving to.

I need to do a code that gave me Original string, uppercase string, lowercase string, reverse string (if letter is upper then convert to lower, and if lower then convert it to upper) and uppercase first (first character of each word in uppercase).
I need to do it in functions but i dont know hot to use strings. The program should provide the option to save the outputs in a file.

I am trying to write a menu program that will be broken down into a series of calls to function for each of the menu items. Two of the menu items will be simple programs which I wrote.
I want two of the functions to run one of the two programs I am trying to include as items in the menu.
So far I am only familiar with variables, loops, if statements, and I just learned how to write functions.
The problem I am have is that I don't quite understand how to write a function that will run one of the two programs. Also I am having a hard time writing the program in away that would allow the user to select the menu items.

This time I need to generate random shapes (circles, rectangles, squares, and ellipses) with random attributes with C, to html.
I am able to create specific shapes with random attributes, but I am unsure how to have the function create a random shape...
Also, the function "box" is meant to create a black border around the shapes. It does this, but I do not know how to make it so that the other shapes do not show up along the lines of this "box."
I guess it appears that certain shapes are "layered" over top of others? ie. My circles/ellipses always show up on top of the rects/squares/box.Currently I have this:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define NO_SHAPES 10
#define X_RANGE 797
#define Y_RANGE 397
[Code] .....

I have a vector of Car* objects - vector<Car*> cars
Each object in the vector has an integer attribute called passengers, which can be returned using the function getPassengers().
How do I sort the vector by the objects' passenger int? I know I need to use sort() and presumably a comparison function but I'm not quite sure how.

i am trying to create a firework display by reading in the fireworks off a .xml file, which will then iterate through and launch each firework.
I followed a tutorial on dinomage to find out how to use tinyxml, i learnt that i can store the attributes into char pointers but i dont know how to convert them to GLfloats to store them in my class variables.
I did try using atof but when i ran the program i got loads of errors which im guessing is because the pointer only stores the address which im passing to my variable.
Update
i have found out that tinyxml is not compatible with vs2010 but tinyxml 2 is, so i have changed my code but am still having trouble loading my attributes i have added error checking, and it prints out that the xml has loaded but then it wont load the root
updated code
my code: Firework.h
Code:
#ifndef FIREWORK_H
#define FIREWORK_H
#include <cstdlib>
#include <GLGL.h>
#include <string>
[Code].....

I needed to change Default Text attributes (font and color) . So I wrote following code , UnicodeTextOut function. I called this function once in each 55ms to update the display screen. but I observed that my Screen used to become grey like a crash after sometime . If I use Minimize an Maximize window , the screen was restoring back for some time.
When I thought over the code , I got my mistake that CreateFont initialization should be done once in the program and probably outside the function.
void UnicodeTextOut(int x, int y, CString s, UINT justify,int GreyScaleFlag) {
HFONT hFontUnicode;
HFONT hfOld ;
hFontUnicode = CreateFont(16, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0, _T("Aerial"));
[Code] ....
Then I shifted the line hFontUnicode = CreateFont(16, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0, _T("Aerial")); in my screen class constructor and made hFontUnicode global .
This solved my problem as expected. Why a system crash after certain no of CreateFont calls ?

I have to write a c++ program to read html code and do bunch of stuff. One thing that i have to do is to count the no of attributes and sort them in descenting out and print out only first 10 frequently used attributes. I counted them using maps and sorted them using multimaps but now dnt knw how to print only 10 elements
for(std::map<string, int>::iterator it = Element.begin(); it != Element.end(); ++it)
Elements.insert(pair<int, string>(it->second, it->first));
for(std::multimap<int, string>::reverse_iterator it = Elements.rbegin(); it != Elements.rend(); ++it) {
cout << "Element: " << it->second << " : " << it->first << endl;
}
This is how i did it . How to display only 10 elements and not all the elements.

I rote this code in my program
JSONNode::const_iterator iter = root.begin();
for (; iter!=root.end(); ++iter) {
const JSONNode& arrayNode = *iter;
std::string type = arrayNode["type"].as_string();
if(type == "node")
[code]......
But when i try to ptint id of second item std::cout<<"Item Id ->>>>>>>>>>>>>" << collection[2].GetId() << std::endl; it gets a blank value. but size of the collection is 82, get the correct value for the collection size.

I'm working on creating a windows form with a listbox, textbox, and 2 buttons (add,remove). I need a way of removing every string matching the contents of the textbox from the listbox. Here's what I have:
for (int i=0;i<listBox1.Items.Count;i++)
{
//...
listBox1.RemoveAt(i--)
}
Seems to work, but I need a way to show a error message once the user clicks 'remove' and no items in the listbox match.

I am creating a student management system (using classes) for my assignment and am stuck with designing UI. I made the classes but am not sure what the best control is to display items from a Dictionary<> object. Right now I am using the ListView because of the columns in details view...just want to know if there is a better, simpler control I could use if i want to display data (without using sql)...or is the good old "next" and "previous" option the simplest?
