My specific request is for retrieving values that are stored to a CompactFlash card. I am able to store values (we call them recipes) to the CompactFlash card as .csv file. I just haven't been able to figure out the code to retrieve this information back to the touchscreen.
Code:
// Create a new folder if it doesn't exist
CreateDirectory("/recipes");
//Create the file if it doesn't exist
CreateFile("/recipes/recipe.csv");
//open the file
hfile = OpenFile("/recipes/recipe.csv", 2);
[Code]....
Now with that said, I would like to retrieve these values from the .csv file.
I am trying to retrieve the first three bits of a number. The code that I am using should work but it isn't giving me the correct result when trying certain numbers. Below is the code I am using:
unsigned short num1, num2 = 0;
unsigned short num = 65535// binary 111111111111111
num1 = num && 0x07;// gives me 1 but should give 7(111)
num2 = num >>3;//gives me 8191, which is correct
Why I am not getting the first three correct bits(111)?

Consider a program that simulates a card game, with multiple player hands and a deck to draw from. Each hand can use an array to represent the cards it contains; sometimes it is useful to also declare an additional variable for each hand (or deck) indicating exactly how many cards are present.
1) Describe a simple function that would manipulate both the array representing a hand and the number indicating the size of the hand.
2) Describe a simple function that might be able to manipulate the array without referring to the hand size variable at all.
3) Generally, if the array was passed as a parameter to a function, how often would the hand size be included as a parameter?
I am doing a project where i need to develop a C# windows application. I need to receive data in my laptop (windows 7) using BLED 112 Dongle from NRF 8001 which is Bluetooth Low Power. Actually NRF 8001 is connected to a sensor and it is streaming the sensor's data. I need to receive those data using Dongle and save those data.
I tried doing this by using the library provided by 32feet.net but using this i could only discover the device but wasn't able to connect my Dongle to NRF 8001. So i couldn't proceed further and i am stuck since couple of weeks already ....
I already tried searching in the internet but didn't find much info however i recently i got a API for my Dongle in this link

I have the records "File attached"
My query is

How do i put the record Accounting in the same row to avoid duplication.
I have a C# program going and want to be able to call the DLL and receive back the data requested through a pointer.Below is the DLL import within my C# code.
Code:
[DllImport("MyTest.dll")]
public static extern int ReadNetwork(Byte[] ROM_ID); Below is the code in the DLL Code: int _stdcall ReadNetwork(unsigned char* Array1)
{
ReadDevice(readBackArray);
for(i = 0; i < 20; i++)
{
Array1[i] = readBackArray[i];
}
[code]....
I've tried changing the return values in the DLL's ReadNetwork() function and that works ok, so I know I'm calling the DLL and it runs ok, but printing the result back is where I'm having the problem.
When i execute the program it gets the right data for the first array but the scound either doesn't work at all or just gets to much data. i've tryed using getline and the "cin" for what the file would be in this case "myfile" there is also one more array that must be retrieved from the file.

I was struggling the last 2 days with this C script supposing to open a list of strings (input as fopen(argv[1])and allowing to access to any element of the list. I created an array *gcm[10000] and a pointer *(*gcm_ptr[10000] = &gcm. However, when I try to list whatever n[i], it always gives me the last entry.

I'm writing a simple text adventure style program in order to practice C++. I originally used char to get whether the user wanted to go north, south etc, requiring they enter W, A, S, or D, and then I used a switch statement, rather than a bunch of else if blocks to move in the appropriate direction. Last night I started updating the code and wanted to require the user type an actual string like "go north" to move, so I'm in the process of converting it over to getline();.
The way it works is the user will input "go north", and if the string is equal to "go north" it will set a variable to 1, 2, 3, or 4, so I can keep the switch statement. The program compiles but whenever it asks for user input, it always hangs waiting for 2 separate lines of input regardless of whether or not you put a space between your command. The move function is as follows:
void movement() {
bool loop = true;
int roomNorth = 0;
int roomWest = 0;
int roomSouth = 0;
int roomEast = 0;
int dirOption;
string dir = "";
[code]....
I read that it could be an issue with getline and the new line characters, which is why I added the cin.ignore in there...so yea the code will wait for 2 separate lines of input and then always outputs "Invalid direction!" regardless of the input.
I have a vc++ project file which reads data from access 2007 database.

How can i execute the above statement with "[String]" without errors?

Suppose your program has many concrete subtypes of Person, and each person will have their own file saved, with their type stored in that file. When reading the files to create the people again (of their proper types), what is the best method to maximize performance (and elegance by shortening the code)? Here is what I have so far.
First I used if statements, which is terrible, and now I've improved the performance logarithmically using std::map. I still suspect there is a better way, especially if there are going to be hundreds of different classes. If you want to test it, you can change the PATH constant to whatever path you want, or just leave it as an empty string, and the files will be created in the same directory as your cpp file. The part I'm trying to improve is pointed out in the comments.
struct Person {
std::string name;
Person (const std::string& newName) : name (newName) {}
virtual ~Person() = default;
};
struct Guy : Person {using Person::Person;};
struct Girl : Person {using Person::Person;};

I have to store large amount of data and retrieve the same data then write into file in C++. Currently I am using vector to store and retrieve. But vector is taking more time to store and retrieve the element. Is any other best data structure to store and retrieve large amount of data in unordered way?
Example code:
int I1 = 700,I2 = 32, I3 = 16;
//declare and resize the vector size
vector< vector < vector < vector<DOUBLE> > > > vPARAM;
vPARAM.resize(I1, vector< vector < vector<DOUBLE> > >

I need to write a program that will allow the user to enter a number "n" and the program tell you that the nth prime number is .....

The deck of cards so it is populated with all 52 cards. Once you have populated the deck, you need to shuffle the deck. Here is a simple algorithm you might consider for this purpose:
For each card up to the middle of the deck generate a random number modulus the size of the deck, swap the current card with the card at that location done
To implement this requirement you need to implement and use the following functions:
void initDeck(Card * deck);
i was reading trying to get it how to display the out put, all i got to is how to declare the arrays. How to start it also i saw some examples have " struct card"
the display should look like this:

3c 3h 3s 3d
4c 4h 4s 4d
5c 5h 5s 5d
6c 6h 6s 6d
7c 7h 7s 7d
8c 8h 8s 8d
9c 9h 9s 9d

I have to develop an application named smart client score board in c#

I found a card shuffling function on a long dead thread.
Code:
for (int x = 52; x > 0 ; x--)
{ y = rand() % x;
temp = deck[x];
deck[x] = deck[y];
deck[y] = temp; }
I do not understand how numbers are not repeated in the function. It seems like it would be possible to get 2 cards with the same number with the above function.
I also am getting incorrect numbers. It seems like I should only get numbers between 1 and 52 (which is what I want). However, I am getting the number 0, and some number between 1 and 52 will be missing, but I will have a total of 52 unique numbers.
I played around with using 51 instead of 52, x > 1, and changed to --x and none of those produced the desired results.
We have to ask the user to select either a Visa card type or Mastercard type. Then, we must ask the user to enter the 16 digit card number and determine if the card is valid or not using module 10. If the answer is zero then it is a valid Visa card and if the answer is zero the answer is a valid MasterCard. My problem is that the I have not separated the validation for MasterCard separate from visa.
Here is what I have so far:

#include <string>

int main() {
string type, num;

I'm writing a card game and I'm having trouble getting the first part of it right, which is picking out a random card from the deck and displaying it to screen. So it's supposed to display a different card every time i run the function in the program. The problem is, I keep getting the same output every time "Nine of Hearts".
This is what I have so far,
#include <iostream>
using namespace std;
//declare two string arrays
//one holds the "suit" of the cards, the other hold the "value"
string suit[] = {"Diamonds", "Hearts", "Spades", "Clubs"};
string faceValue[] = {"Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ace", "King", "Queen", "Jack"};
[Code] ......
This is the output I keep getting every time I run the program:
Nine of Hearts
This "random selection" function I'm trying to do is meant to work as a means of shuffling the cards in the beginning of every round in the game and displaying only the top card from the deck.
