C Sharp :: Coding For Quantities In Online Shopping Carts?
Jan 11, 2013
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 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.

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:

My project is on an online shop in which you can manage a shop(adding ,deleting ,clearing and modifying items) also you can switch to different shops(all shops are same)
Code:
#include<iostream>
#include<fstream>
#include<conio.h>
#include<stdlib.h>
#include<string.h>
[Code] ....
The logical problem is serious because i am not able to find the error!!! There is some problem with display lines in void shop()-->if(mode=='s') and if(mode=='d'). I add only one item but in output screen i see two items(sometimes >2)
*note* to run the above display lines in the output screen....first register--->add atleast one item--->see your shop

}
I need a stopping case when user press enter array get closed and add '' at the end but how to do that?

This program works on an online compiler but force closes on codeblocks after entering the elements.
#include<iostream>
using namespace std;
int two_print(int x, int one[999]) {
int two[999][999];
for(int k=0, r=x; k<=x; k++, r--)

I have a script that checks and compares two lists from an offline dictionary. Dictionary.txt which has a lot of words in it. input.txt will compare to dictionary.txt and print out anything that matches in CMD.
However, instead of using an offline dictionary is there anyway to make a code check an online dictionary? If so, would this process be slow or fast?

I want to make an online application which will connect to my database to do the stuff, but I don't want the credentials to be stored somewhere in the program or in an external file somewhere in the computer or hardcored in anyway in the code.
I think that a good solution is (but I don't know how to implement it): on program execution, the credentials will be downloaded from my website somehow in an encrypted type maybe, from an api or so.
I've not tried before to make an online application, it's the first time. But I do have knowledge of SQL and PHP and I want to try a project like this.
The technology I am going to or can use is:
* Visual C# (in Visual Studio 2010 Ultimate)
* MySQL Connector/NET
* MySQL Database on a shared host
* PHP (if needed)

I just spent 3 hours writing and debugging 37 lines of code. Is this normal or am I "below average" in coding abilities. I come from a C background and decided to write C++ code that I finally got right as shown below for the specific example:
Code: #include <iostream>
#include <fstream>
#include <string>
#define SPACE_SEARCH 10
using namespace std;
[code].....
I think it was more the learning along the way that consumed atleast 75% of my time for this specific case. But then again, I read that programming always entails learning along the way and so its somehow no excuse for the long time taken in this specific case.
So as a matter of interest, what pace do all of you operate on, on average? i.e. LOC/day, Debugs per day or any other indicator of productivity?

Im having problems coding this
A = P(1 + r/n)nt
//Declared test cases
float principal = 200000.00, annualInt = 0.03;
float years = 10.0;
float calcInterest1(float principal, float years, float annualInt) {
float interest1;
float nt = annualInt*12;
float A = principal+annualInt;//Accrued Amount
interest1 = (A = (principal*(1+years/100))pow(nt));// A = P(1 + r/n)nt
return interest1;

Write a program that computes how many feet an object falls in 1 second, 2 seconds, etc., up to 12 seconds.
1.Have a procedure called FallingDistance which has one input parameter, seconds, and one output parameter, distance.
2. Compute the distance in feet an object falls using this formula: d = ½ gt2
(where g = 32.2)
3. The main program should call FallingDistance within a loop which passes the values 1 through 12 as arguments.
4. Print a table with seconds and falling distance in feet.
Sample Output (This program has no input)
Seconds Distance
================
1 16.1000
2 64.4000
3 144.9000
4 257.6000
5 402.5000
6 579.6000
7 788.9000
8 1030.4000
9 1304.1000
10 1610
11 1948.1000
12 2318.4000
In C++, the procedure is called a function. Instead of using an output parameter, your C++ function FallingDistance should return a result of type double. This is what I created:
#include <iostream>
#include <cmath>
#include <string>
using namespace std;
const double g =32.2;
double fallingDistance(double);
[Code] ....
which gave me this error:
1>------ Build started: Project: Lab 6, Configuration: Debug Win32 ------
1> Source.cpp
1>c:usershanahdocumentsschoolprogamming ilab 6lab 6source.cpp(27): error C2065: 'fallingdistance' : undeclared identifier

I am writing a program where all work is done in the class methods. Main is used to call the methods. I need to know how to get a loop to work without any variables in main that can be used outside the methods. This is what I have in main:

#include <string>
using namespace std;
#include "FerryBoat.h"
int main() {
//create a constructor for a ferry boat
FerryBoat myBoat('B', 20, 'A');

I have to do a strobe moodlight lab and it says to use ticks. But I don't quite understand ticks. Do you just input it in like Ticks 1 = new Color(0,0,0); or do you have to do something do something else.
