C :: How To Read Data In A File And Print It Then Copy Contents To A File
Mar 8, 2013Code:
#include <stdio.h>
#include <stdlib.h>
int main (int argc, char *argv[])
{
char buffer[256];
FILE * myfile;
myfile = fopen("read.txt","r");

I also got an error in printing wherein the data in read.txt is "Hello" newline "World" and my program prints world twice.
C :: Write A Program To Copy One File To Another?
Feb 11, 2013Here I was trying to write a program to copy one file to another.
Code:
#include <stdio.h>#include <stdlib.h>
int main(int argc, char *argv[])
{
FILE *fp , *ft;
[Code]....
So it should copy test1 to test2. Now I created test1 in gedit. I just put one character "c" in it and closed it. And I ran the program. When I check sizes of test1 and test2 , using
ls -l
command, I see that test2 has 4 bytes and test1 has 2 bytes. So something strange is happening here. I just put a single character in test1, so shouldn't it show 1 byte ? And why test2 is showing 4 bytes ? I have Win XP on my laptop. And I use Ubuntu 12 inside VirtualBox. So this is Linux environment...

C++ :: Copy Data From One Text File To Another?
Jan 14, 2013I need to copy data from one text file to another.This is how data in file looks like:
2 -3 8 5 0
3 5 1
2 -2 3 1 7 6
5 -3 15 0 1
I succesfully managed to copy those numbers but with one mistake.The last number is written twice. My output file looks like this:
2 -3 8 5 0
3 5 1
2 -2 3 1 7 6
5 -3 15 0 1 1
This is my code:

C Sharp :: File Copy From One System To Another?
Jan 23, 2013I am making an application that runs on Machine1 and the purpose of the application is to copy the files from Machine1 to Machine2. It works fine but i have to share the folder of the Machine2 where i copy the files.
Is it possible without sharing.
C/C++ :: Program To Copy A File From Source And Paste With Different Name
Mar 6, 2014I have written a program that copies a file from the source and pastes it there (same location), but with a different name. The program works fine, except there is a small bug that i can't seem to fix. Here is the code:
/*
This program copies a file from the current directory and pastes it to the same directory, but with a different name. The file name form the source must include the extension as well.
*/
#include <stdio.h>
#include <conio.h>
#include <stdlib.h>
int main() {
char temp, s_file[100], d_file[100],
[Code] ....
This is the flow:
> 1) Enter the name of the file you'd like to copy (Must be from the current directory)
> A: 3.c // This depends if the file exists in the
> current directory
>
> 2) Enter the name of the destination file (The file will be copied to the same directory)
> A: 4 //The extension isn't necessary here
>
> Result: The file was copied successfully!
When I run the prg again, and this time input a file name with no extension, like this:
> Enter the name of the file you'd like to copy (Must be from the current directory)
> 3
> You did not enter a valid text. Press "?" to get help or "x" to exit.
I hit "?" and it takes me to
> 1. The file must be from the current directory)
> 2. The location mustn't be empty
Then it asks me
> Try again? (Y/N)
If i give N, it exits. BUT if I give Y, it goes, like this:
> Enter the name of the file you'd like to copy (Must be from the current directory)
> You did not enter a valid text. Press "?" to get help or "x" to exit.
You see, it doesn't give me the option to give it the file name..

C++ :: How To Copy Strings From File Into Array Of Pointers
Jan 13, 2014I am trying to copy string Line BY Line from text file into array of pointers. lets say file has only two lines for example.
This is an apple.
This is another apple.
I want to copy both of these lines from file to array of pointers. Below is the code which i am trying to use for this.
Code:
#include <iostream>
#include <stdlib.h>
#include <stdio.h>
#include <fstream>
#include <string.h>
using namespace std;
int main() {
char const *filePath = "test.txt";

C++ :: How To Copy Between Vector
Feb 15, 2013btw this is a part of my program

//READ OPERATION--ONE EXECUTION ONLY
if(file.is_open()) {

the 'flds' on the code above has vector <string> data type, i was able to output it using cout but i don't know how to copy its value to another vector <string>...whenever i tried to do that using my own way, the compiled program ended up crashing...
C++ :: Copy 3D Vector Into Another?
Feb 17, 2012I have the following function:
Code:
void fillVectorWithNumbers(vector<vector<vector<double>>> &vI3) {
const long dim1 = 10;
const long dim2 = 16;
vector<vector<vector<double>>> vI3Temp(dim1, vector<vector<double>> (dim2, vector<double> (dim2, 0.0f)));
[Code] .....
So basically I need to copy vI3Temp into vI3. I assume I can't loop over each element because I haven't sized vI3. So I guess I need some push_back for this. But what code to use?
C++ :: Copy Array Into Pointer
Jun 20, 2013I have written this code, and at first glance it does what I want, however I am worried that
a) I am overwriting the array that is apssed from chord.getPattern()
b) Im getting a memory leak that I want to get rid of, and
c) is there generally a /what is the neater way to do it:
Code:
uint8_t* ChordBuilder::invert(uint8_t count, Chord chord) {
temp = chord.getPattern();
chord.invert(true);
//TODO count is how many times to invert. Moves root aswell however
for (uint8_t i = 0; i < count; i++){
[Code] ....
temp is a member variable of ChordBuilder - and is expressed as: Code: uint8_t* temp; I dont want the pattern that chord stores, and passes with getPattern() to change - I fear it is at the moment?
I would rather not use the "new" but I cant think how to get rid of it, however Im not sure where I would need to put the "delete"?

C :: Copy A Character To String
Mar 6, 2015Copy some characters from char * arg to char * first using a loop with specific conditions.
Code:
char * arg;
// set arg some string...
char first_[25];
char * first;
int length;
length=strlen(arg);
for (n++; arg[n] != '}' || n>=length-1; n++)
strcpy(first,arg[n]); // first += arg[n]; I have strcpy(first,arg[n]); but arg[n] is char and strcpy expects char * ;
how to solve this?
C :: Copy Only Elements Of String
Apr 14, 2014My goal is to copy only the elements of string 2 that are equal to string 1 into a new string. I tested this idea with an array of integers and it worked, but didn't work for the strings.
Code:
#include<stdio.h>
main()
{
int scan1;
char arr1[40] ;
char arr2[40] ;
char arr3[40] = {'_',.....,'_'}; /*for sake of brevity with post*/
}

C++ :: Pass By Constant Copy
Jun 16, 2014I have never seen anyone pass by const copy and there probably is a reason. I know that the compiler ignores top level const-ness of function arguments. There are functions which take arguments without manipulating those arguments return the result, for example the C Standard Library funcion double sqrt (double x). The function shouldn't modify it's argument, but it can since the argument isn't const.Take these two functions for example:
double square_root_1(double arg)
{
arg = 7; // we won't get the desired results
return arg * arg;
[code]....
So isn't it better to pass by const copy to make sure that you (or someone else) don't by accident modify the argument? The only disadvantage I see is that it makes the code too verbose.
C++ :: When A Copy Constructor Is Called
Apr 27, 2013The following are the cases when copy constructor is called.
1)When instantiating one object and initializing it with values from another object.
2)When passing an object by value.
3)When an object is returned from a function by value.
I don't understand #2 How can and object be passed by value? when I think of passing object I think of passing by address or reference. explain
I don't understand #3 how can a function returned object by value I think of again passing by address or reference.

C++ :: Destructor Is Called After Copy
Sep 17, 2013Whenever my copy constructor is called, my destructor destroys is immediately after.
My copy constructor
CS1CStudent::CS1CStudent(const CS1CStudent& otherCS1CStudent)
{
cout << "
***************************
";
[Code]....
The copy constructor is called twice, once when you pass an object by value, and once when the object is returned from a function by value. But why is the destructor being called twice?
C++ :: Create A Copy Constructor?
Dec 11, 2013copy constructor. I'm not really understanding them. I have a base class called Vehicle and a derived class called Car.
class Vehicle
{
private:
int age;
[Code].....
I'm trying to test the new attributes and behavior of car but I think its not working because of the copy constructor. Its just not clicking. I also forgot that race car status is supposed to return yes or no, am I defining that right?
C++ :: Copy Constructors In Inheritance
May 16, 2013#include <iostream>
using std::cout;
using std::endl;
class CBox // Base class definition
{
public:
// Base class constructor
explicit CBox(double lv = 1.0, double wv = 1.0, double hv = 1.0) : m_Length(lv), m_Width(wv), m_Height(hv)
[Code] .....
This example produces the following output:
// Derived class copy constructor
CCandyBox(const CCandyBox& initCB): CBox(initCB) {
std::cout << std::endl << "CCandyBox copy constructor called";
// Get new memory
m_Contents = new char[ strlen(initCB.m_Contents) + 1 ];
// Copy string
strcpy_s(m_Contents, strlen(initCB.m_Contents) + 1, initCB.m_Contents);
}
It will work right? Cause when I do "CBox(initCB)" it only sends the BASE part of the derived object to the base class copy constructor, is it copy or default?

C++ :: Copy Constructor And Destructor?
Nov 21, 2014Class Car{
Private:
string* _ID;
bool _isFaulty;
int _location;
int _timer;
int _order;
vector<Road*> _roadPlan;
}
I want to implements Copy constructor (deep copy) and destructor, and I don't know how to treat the vector of pointers (Road is an object too)
Mor
Another thing, maybe I'll prefer using List instead of Vector, so i would like to see an implements of Copy constructor and destuctor with List too,
C++ :: Copy Constructor Containing Pointer?
Nov 24, 2014I want to copy over values from x to y, and its not possible as i cant use "y" as a index in my pointer array.
Code:
CellularPhoneStock::CellularPhoneStock(CellularPhoneStock &origObj){
this->phonez[nrOfPhones]->setColour = origObj.getColour();
/*this->model = origObj.model;
this->nrOfType = origObj.nrOfType;
this->price = origObj.price;*/
nrOfPhones++;
}
My questions is, how can I use origObj and phonez combined to use the function getColour() ?
Btw, phones = CellularPhone * phonez[30];
C# :: Sbyte To Int - Copy Only Bits
Jan 15, 2014I just have a short question! I have an sbyte and I want to convert it to an int, but I do not want a value conversion, just to copy the bits, such that the negative numbers in the sbyte will be their complement in the int (-12 in sbyte -> 244 in int)... How can I do that?las
