C++ :: Merging Two TXT Files (Adopted And Original)
May 11, 2014
I'm trying to merge two files, The Adpoted.txt, and The Originals.txt, into one file, The Big Picture.txt. I'm compiling and getting an insane amount of errors, and am not even sure where to start with them :(. I'm getting errors for lines that don't exist. I suppose I should start with those that do!
#include <iostream>
#include <fstream>
#include <cstdlib>
using namespace std;
#define theAdopted "The Adopted.txt" //His family
#define theOriginals "The Originals.txt" //Her family
#define theBigPicture "The Big Picture.txt" //Our family
int merge(ifstream&, ifstream&, ofstream&);
I'm writing a program to merge all .txt files in a directory. I had the code working and then made small change. It started crashing and I couldn't get it back to working.
If I comment that section out, the code still works. But, I know that portion of the code works to copy text from one file to another! It's actually from the Schildt complete C reference and I have tested it several times on it's own.
I have come up with code for this, but am currently having issues finalizing it. It seems that it only puts out some of the numbers in a numerical order, but not all from both text files.
i need to write a c++ code which can merge contents of several .txt files into a single file. i used the following code , it works but after merging the result file contains the contents merged twice.I think it over writes the result.I want to do it without using command line.
#include<iostream> #include<fstream> using namespace std; int main() { std::ofstream("merge.txt"); system("type *.txt >> merge.txt"); system("pause"); return 0; }
The directions are to write a program that reads sorted integers from two separate files and merge the contents of the file to an output file (third file). The only standard output will be any errors to be reported and a “FINISHED” statement after all items have been processed.
file1.txt 2 4 6 8 10
file2.txt 1 5 11 12 15
Output.txt 1 2 4 5 6 8 10 11 12 15
This is the code I have so far, but it is not working, and I have put the two txt files in the same directory as my .cpp file. It is not working though still. What have I done wrong and how can I fix it to read these integers from the two numbers and merge the contents into a third file?
#include <iostream> #include <fstream> using namespace std; int main() { int num1; int num2; ifstream inputFile;
Write a program that opens two text files (input1.txt and input2.txt) for input and one for output (output.txt). The program should merge the two input files in the output files. While doing the merge, it will read one line from input1.txt and one line from input2.txt and write those in the output file one after other. Then it will read the next line from input1.txt and next line from input2.txt and write them one after other in the output file.
This is my code:
#include <iostream> #include <fstream> #include <string> using namespace std; int main() { ofstream myproject; myproject.open("input1.txt");
[Code] .....
I need to:
1. how to get the second line in the input1.txt file and so on. 2. After the writing in output.txt, count the number of lines in output.txt. 3. write the number of times term ‘line’ appears in output.txt file.
I'm having an issue with merging two files. Basically, my instructor gave me pseudocode and two files to merge together. Each file (a male client and a female client file) has three names and id numbers inside. The finished MergedClients.rtf should have all six clients in ascending ID order. I wrote the C++ code and after combing through a couple times to fix a few errors, it finally ran. The problem is it starts the process, but it doesn't ever finish.
I tried changing some of the bool expressions thinking I mixed up the true and false parts. After that the program ran and it created the new output file, but the file was empty. So, I don't think I mixed any of those expressions after all.
#include <iostream> #include <fstream> #include <string> using namespace std; int main(){ ifstream inFile1; ifstream inFile2;
I'm learning to merge files, but I think I'm getting it all wrong.I'm trying to merge two .txt files, and have them alphabetized on the output file. I'm getting a couple of error codes that I'm not sure of.
These are my errors:

how to combine two bytes (each byte is 8 bits wide) in order to get the original value. I am displaying values(from 0 to 500)sent from my microcontroller on the GUI.I can successfully display values from 0 to 255 as this requires just sending a byte. However sending values from 256 to 500 requires sending two bytes. The problem I am having is that I was unable to re-combine the received two bytes in order to get the original value. Below are my lines of code:
int main( void ) // this is the main function inside the microcontroller { sei(); USI_TWI_Master_Initialise(); Spi_Master_Init(); while(1) // I am using this loop to send 500(111110100) { Transmitt_Receive(244);//this function sends LOW BYTE of 500(11110100) _delay_ms(1000);
[code]....
When I combined the two bytes using the above arrangements, instead of getting 500 my GUI displayed 62708.I got the same result when I used BitConverter.
I have a set of n- dimension point store in `vector< vector<double> >`
ex A[0][1].............[N], and A[0][0] = X, A[0][1] = Y, A[0][2] = Z
and I want to sort the vector of all of the dimension
ex sort X, Y, Z ,.........N in ascending order
ex A[0] = (1,5,3), A[1] = (3,2,1) A[2] = (2,8,4) after sorting index: 0 1 2 A[0] = (1,5,3), A[1] = (2,8,4) A[2] = (3,2,1) original index : 0 2 1
I find that `sort(vector.begin(), vector.end())` can sort it but how can I record the original index with a additional vector?
Is there a algorithm or C++ feature can solve it?
I have tried to solve it with a class wrapper it but I don't know how to write the compare function.
class point{ public: point(int totalLength = 0, int elementLength = 0); vector<vector<double> > pointSet;//store the n-D points vector<double> pointIndex;//store the index }; point::point(int totalLength, int elementLength){ pointSet.resize(totalLength,vector<double>(elementLength, 0)); pointIndex.resize(elementLength); }
I've been taking a C++ class, and for a project we need to do, we have to create a simple quiz show game while putting the high scores and names inside a .txt file. We have lessons we can look at to complete it while learning. But at the end there's always a challenge that we should complete to show that we've actually learned the information. For the challenge, we needed to take the information in the .txt file and reset it to its original information. So say there's 5 people preset that have high scores, then a person plays the game and the program asks if they'd like to reset the list. If the user inputted 'y' or any key that needed to be pressed, the program would reset the .txt to its original information.
This is the code that creates the program.
// Include Libraries #include <iostream> #include <string> #include <fstream> // Include standard namespace using namespace std; // Declare Global Variables int Guess; int Winnings;
[Code] ....
It works how I need it to and there aren't any problems, necessarily, but I want to know if there's any, more efficient, ways of completing this task. Like if there's any already made function of resetting a file.
This is the code that resets the file. As you can see, it just uses the information earlier in the code inside the if statement. Is there any pre-made function or method of resetting a file?
cout << "Would you like to reset the high scores list? (y or n): "; cin >> ask;
I have created this program to merge two linked list into one ,but however everything is working fine but on execution it providing a segmentation fault error ( on calling merging function )
code :
#include<iostream> #include<stdio.h> using namespace std; struct node{ int data; node* link;
Write a program using user-defined function to merge the contents of two sorted arrays A & B into third array C. Assuming array A is sorted in ascending order, B is sorted in descending order, the resultant array is required to be in ascending order.
i've just started learning building structures in c++ and they gave us an exercise of writing a recursive merge code of linked lists - just merging without sorting... i don't even know how to start this is how i started so far.... i know that the break in the recursive function is when i get to the end of the first list and then to start linking the second list..as you can see i wrote a function that uses recursive function...
LIST merge3(LIST lst1, LIST lst2) { LNODE* curr1 = lst1.head; LNODE* curr2 = lst1.head; LIST mergeList; mergeList.head = NULL; mergeList.tail = NULL;
I am having to write a program that takes 2 sorted linked lists (x and y) and merge those to sorted into a third one (z). This has to be done via recursion. I think I am close but there is a logic error.
merging 2 or more pdfs using itextsharp. I have 2 methods that fill a pdf template each and saves them to a memorystream and a downloadAsPDF methods to return the combined pdfs to the broswer. the downloadAsPDF works when i add only one of the memorystream but when i add both MemoryStreams to the list I receive the message...If this message is not eventually replaced by the proper contents of the document, your PDF viewer may not be able to display this type of document.
public byte[] fillTemplateA() { String NfoodAllergyTemplate = "~/pdfTemplateA.pdf";
I have same question as posted by holla and Iam not sure about merging the contents of 2 sorted arrays into another array without duplication of values.
I am working on VS2008. I have two separate projects which have almost same functionality along with same file names but few are different. So I decided to use the same .cpp and .h files for both the projects. Both are Dialog based applications.
So what I did is I merged the source code changes to one by using #ifdef XXXX in all the common .cpp and header(.h) files.
I also moved the .rc file and .vcproj file to other project (As they were of different name).
The problem is with the resource.h file, as it is the file with the same name in both the project. By using #ifdef XXXX in .cpp files the compilation is working file but here in resource.h the resource is getting corrupted and the diglogs are not getting displayed.
