C++ :: Program To Make Shopping List - One Line Per Entry
Jan 9, 2015
OK I'm making a simple program to make a shopping list. I would like the program at start up to load the previous shopping list that was saved as a text file. The format is one line per entry which consists of the category or Isle, and the item description. Here's an example:
3 Dog Food
Produce Sweet Onions
I reading the first word, and then I want to read the rest of the line which may have more than one word... the problem is my code hangs... or goes into the old infinite loop. It doesn't see the end of file.
Here is my code:
void
addItemsFromFile(vector<item> &shoppingListVector) {
string word;
char buf[30];
if (fileExists("shoppinglist.txt"))
[Code] .....

I have written an program to emulate a shopping list. Everything works fine, until I try to read in from a file. Here is my read and write code (the write code looks like it is working ok, but I figured I would include it just in case), and an example of what happens to a list that has been written, then read back in.
I took this list, and wrote it to a file, then read that file back in. The .txt file looks like everything was written out properly, but when I try to read that exact same list back in, this is what I get:

I am new to programming, and trying to make a C# Windows Forms program, to easy our weekly dinner-planning.
I would like to make something the work like the attached Picture.
A combobox for each day, where i can select a stored dinner with recipe.
To the right it will automaticly make a shoppinglist, which I can print.
If for example i have selected 2 dinners which both needs 500 grams of meat, i should automaticly write 1000 grams of meat.

I'm learning C# and having fun and I've been practicing by working on this little data entry console application. Basically the user inputs first name, last name, age, gender, employee id, then I ask the user if he/she wants to add another entry, if yes then loops back at the top, and if no, it prints out the amount of entries added. The issue I'm having is that the entry list is never kept or stored when adding another entry, it replaces what was entered before which is not what I'm looking for. I don't know how to stuff one entry list information seperately in an array so that I can print out which ever entry the user decides to choose once he/she is done adding entries. Is there a way to make this work?
Here is my program code:
using System;
namespace Ch02_Exercises_12
{
class Program {
static void Main() {
string firstName;
string lastName;
string input;
sbyte age;
char gender;

So I'm reading a file line by line and storing it backwards into a list. So if the file has has this format...
1
2
3
4
The code should store each line in a list as such...
4, 3, 2 ,1
Instead the code will store the last variable in all nodes. So the final list will look like this...
4, 4, 4, 4
Here is my code...
struct node *head = NULL;
int i;
while(read(in, &i, sizeof(int)) != 0) {
struct node *temp = malloc(sizeof(*temp));
temp->line = &i;
temp->next = head;
head = temp;
}

I am trying to create an on-line product store. I'm having trouble with setting up the code to correctly acknowledge quantity desired per product item in the shopping cart at check-out. I want to be able to capture multiple impressions/hits/clicks per item and increase the # in the quantity box each time someone clicks on the same item. For example, if product A is clicked 3 times, then the quantity in the shopping cart should show "3". If it's clicked 5 times, it should show "5" and so on ... However, right now, it's showing the product multiple times in the shopping cart with a quantity of "1" for each time the item was clicked. How can I correct this?

I want the numbers to be put into the array until it hits a new line. Maximum number of numbers is 1000. What can I replace that while loop with to stop it from reading further into the input file?
Code:
while (input != '
'){
for(i=0; i<1000; i++)
fscanf(ifp, "%lf", &auctions_prices[i]);

I want to make an object, which moves from x1,y1 to x2,y2 in a straight line, also make a sinus over the line (so the x,0 is the line itself, and cux,cury is the object. So the object will move as a sinus over the line. How do I do this in c++?

I have this program. I am trying to do this Circular List but i think something going wrong. The first of all is the list.The second is if my code for delete and select function are correct and the third i would like my program getting a "n" number of names and then make the circural list then print it and then when i select a number delete every node until give us the only one left.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define SIZE 10
#define NUM_PER_LINE 6
typedef struct node {
char name[SIZE];
struct node * next;

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?

My program takes in an input file from the command line and converts the string from the file into a linked list and then depending on the command it will manipulate the string to either reverse the list, print the list, or take a character out...I'm having trouble taking a character out, my code compiles fine but doesn't change the string at all
Code:
#include <stdio.h>
#include <stdlib.h>
#define SIZE 1024

So for class I have to make an array of structures for a basic contact list in a phone.
I understand the bones of the program and how to go about doing most of it but as far as arrays of structures go I am blind.
Code:
struct phone
{
char FirstName[16];
char LastName[16];
int Number[11];
};
struct phone numbers[friends]; //friends is a variable assigned by the user What I am a bit confused about is say the user enters 30 as how many friends they have. How would I assign a value to the 3rd struct for LastName?

I am trying to make a linked list. When I compile my code, I get an error saying 'current' is not declared in this scope. I don't understand because I have declared in the first line of my functions body. The variable is local to the function so I don't understand what the problem is.
#include <iostream>
#include <cstdlib>
using namespace std;
class LinkedList {

I have created a program which does tokenization to the whole line. The basic idea is if you have this ***HELLO%%SIR.
Then you have 8 tokens (2 words + 6 symbols). My algorithm is the following :
BEGIN OF THE LOOP
IF CHARACTER IS NOT AN ALPHABETIC LETTER
INCREASE THE COUNTER OF ITEMS ONE TIME
INCREASE THE COUNTER OF ARRAY ONE TIME
END IF
[Code] ....
And here is the implementation :
[C] C Words Tokenizer - Pastebin.com
First of all it is not an exercise from university. It is my reflection. What is your opinion about that exercise? It is useful? Tokens must be only the words between delimiters? I am analyzing the whole line.
Secondly I want to print the symbols and the words I don't want to use strtok to do this because I think that function line_tokenizer will not reusable due to strtok and the fact that puts the ' ' after the word each time it is called. (strtok) Is there any other idea in order to have the OUTPUT :
Code:
Give the sentence:
***HELLO%%SIR.
Analyzing...
The line has 8 token(s).
Symbols : ***%%.
Words : HELLO SIR
