I have written a tar program and now I can take files add them to a tarfile and extact them into another directory. The problem is that it doesn't work with jpegs.

The problem is that it does not take any values ps I have been learning C++ for 3 months so we don't have any arrays,at max we have iterations
I want to get or view the SIM card number from the dongle (the dongle will b already connected to the computer where the SIM card will be inserted into it) but the coding should be done by C programming / Language.
View 5 Replies View RelatedConsider 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 have a program that stores health information the user inputs, one person at a time. The program works perfectly with the exception of storing the data...I need to open a file and read what health data it has in it already, if any, but store the new changes, and appended data to the array of structures, to the data in memory. All of the information is only saved back in the file once the program terminates. I'm not sure how to go about doing this, so I am also not sure what to put in the function for "Save and Exit" that the user can choose in order to exit the program.

I tried playing around with this bit of code, but I'm not sure if I'm even on the right track.
Code:
FILE *fp;
fp = fopen ("students.txt","rb"); fseek(fp, 0, SEEK_END);
long pos = ftell(fp);
fseek(fp, 0, SEEK_SET);
char *bytes = malloc(pos);
fread(bytes, pos, 1, fp);
fclose(fp);
I'm taking a CS course and we've been tasked with creating a program that recovers jpegs from a formatted CF card which uses the FAT file system with a block size of 512 bytes, the jpegs in the card are block aligned which means that the beginning of a jpeg marks the end of the former.
I've wrote the program and it works nicely and recovers the 51 jpegs in the CF card (actually just an image of some 4-5 megabytes of the actual card which can be downloaded here) but I'm looking for ways to optimize/improve my code so I need a second look from experienced programmers.
Here's my code:
Code:
/*
* filename : recover.c
* description : Recovers jpegs from a forensic image
*/
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <stdbool.h>
#define BLOCK 512 // fat file system block size
int main(void) {
// open CF card image
[Code] .....
My questions are:
1) What are the possible optimizations that can make my code faster/better/more concise?
2) I'm not handling slack space, since trailing zeros at the end of a jpeg won't affect rendering it (we were told it won't contain any garbage values)... how may I approach the problem?
3) Can I enhance my if else constructs? or even replace them with something more elegant?

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:

4c 4h 4s 4d
5c 5h 5s 5d
6c 6h 6s 6d

I have to develop an application named smart client score board in c#
Main requirements for this application are that application should display the live scores, detailed score board, running commentary (in text), players and team profiles, statistics of matches, results and fixtures for cricket.
sort out websites which support rss feeds for full score card.
How do you store a variable in memory so that it isn't changed when the program closes? I don't have any experience with this and am just wondering how it is possible. I am creating a program and want it to store your preferences and scores. In a simple program, everything is just reset and I don't want this for my program. How do I store a variable so that it stays the same, but can be changed even when the program is turned off?

Write a C++ program that had a base class PLANT with a sub class of that of TREE. The Program works exactly to her specifications except there is a memory leak.

tree.txt - For Input
plantReport.txt - Output of Program. No cout is really allowed by her.

MainDriver.cpp - Contains int main()
I'm searching a program that can detect a special type of memory leaks, like these:
int a = 12;
char c[10];
char cc = c[a];
I have an assignment that wants me to better understand how certain calls like malloc() and free() work. I'm supposed to have one function that allocates a pool of memory for the program to use (this is the only place where I'm allowed to use the malloc function. Anyplace else is off limits, except when allocating space for data structures.) Another function needs to be defined that allocates memory from this large pool of memory that we have already allocated. A third function needs to free a block of memory when a call from function main is made and a fourth does something else (haven't gotten that far yet.) I'm not sure if it's ok or not, but I'll attach the pdf form that describes all the requirements. If that's not ok, I'll delete it.)
Anyways, when thinking of data structures to use for this particular problem, one doesn't jump out at me as being THE data structure that would be most useful. How I would imagine using it is to store the addresses currently being used as well as the block length of those addresses (so basically, each node of the linkedlist would have a pointer that points to an allocated address and another field that told the size of the allocated block of memory.) How to communicate to the large pool of memory that a certain block of memory has been allocated and shouldn't be used until a free is made on that specific block of memory.

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:

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.
I almost finished a program but am stuck on sorting the hand im dealing with qsort. sorting by the face values and if they have the same faces im suppose to follow this suit order to determine which one is greater (Clubs, Diamond, Hearts, and Spades) how would i adjust my comparator function to do this for me ?
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define DECK_SIZE 52
struct card {
const char *face;
const char *suit;
