i am trying to doing my project what is: Diff - The program should compare two text files and list the differences, i.e. lines and columns of the beginning and the end of a given difference.
i dont know how to start or what to do with this.
I want to make a program that opens a text file and checks the usernames listed in the text files to see if the names are registered on a site such as twitter. How easy would this be to make, what things would I need to know?

I'm writing a code obfuscator in C. Debugger shows no errors in the code, but the program crashes after compiling -- I'm guessing it has something to do with while loops or reading data from files.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
// list off all replaced elements
typedef struct ReplaceList {
char *from;// from string
char *to;// to string (random)

Basically I am to create a program that will read two saved text files; one is [2x4] ~ (matrixA.txt) and another is [4x2] ~ (matrixB.txt). The program is supposed to read both text files, multiply them, and generate an output that will be saved as ~ (matrixC.txt).
So here is my horrible attempt at it:
Code:
#include <stdio.h>
int main() {
FILE * fileA;
FILE * fileB;
FILE * fileC;

And these are the compile errors...

I am trying to make a simple program, I would like it to be able to do the following, Write a program that opens two text files (input1.txt and input2.txt) for input .The program should write the followings in the two files. input1.txt:
This is the first line in input1.txt.
This is the second line in input1.txt.
This is the third line in input1.txt.
This is the fourth line in input1.txt.
input2.txt:
This is the first line in input2.txt.
This is the second line in input2.txt.
This is the third line in input2.txt.
What would be the best way to go about doing this? I wrote the program below, but I don't think that it works.
#include <iostream>
#include <fstream>
#include <string>
int main()

How to compare two files(two texts documents) and display their similarity percentage by using C++?
View 10 Replies View RelatedI am writing a piece of code that requires me to display the last 1000 lines from a multiple text files (log files). FYI, I am running on Linux and using g++.
I have a log file from which - if it contains more than 1000 lines, I need to display the last 1000 lines. However, the log file could get rotated. So, in case where the current log file contains less than 1000 lines, I have to go to older log file and display the remaining. For e.g., if log got rotated and new log file contains 20 lines, I have to display the 980 lines from old log file + 20 from current log files.
What is the best way to do this? Even an outline algorithm will work.
I need to compare the words from a text file with words from an array (which i got from another file) and count the instances of those words. I thought about making another array but that doesn't make sense since the text file may have a lot of words in it.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>
int main() {
FILE *myFile;
char words[100][40], test;

the test variable in the last for loop is wrong i know i was just trying something.
I am writing a program to hide files behind other files using Alternate Data Streams in Windows NTFS file systems.
The program is as follows:

printf("Enter the name(with extension) and path of the file whose behind you want to hide another file: ");
scanf("%75s", hostfile);

I am working on a String compare program and i got the program to work properly i was just wondering how to put user input into quotes.
here is my programming
int main {
const int LENGTH = 40;
char s1[LENGTH], s2[LENGTH];
cout << "== String Compare ==" << endl;
cout << "Enter a word" << endl;

the input is :
Dorito
dorito
the output needs to look like this:
"Dorito" comes before "dorito".
I have a text file that contains values as follows:
2013 05 27 15 52 02.049824 231.401 0.022 49.738 2013 05 27 15 52 02.668822 229.814 0.019 49.738 2013 05 27 15 52 03.283705 228.528 2.599 49.726 2013 05 27 15 52 03.898469 230.140 2.576 49.751
Column1=date, Column2=Month, Column3=Day, Column4=Hour, Column5=Minute, Column6=Seconds, Column7=Voltage(Vrms), Column8=Current(Irms), Column9=Frequency(Hz).
I have to develop a program that will analyse these time-sampled voltage and current measurements over 24 hours and find the total energy used, mean and peak power consumption and Energy used over each hour of the 24 hour period.
How do I go about doing this? I also need to include at least one numerical integration technique. The file data contains over 50 thousand lines in the format mentioned above.
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.
#include <iostream>
#include <fstream>
#include <cmath>

So I'm trying to output 2 different text files, one has customer names and the other has items they are selling. I gave each customer an ID and each of their items has the same ID. Only problem is when I try to output it, it only outputs the first item with the same ID. I do not want to display the ID number at all, I think getline would show it so I am not using it.
here's my code
ifstream infile, infile2;
string Fname, Lname, email, item, itemPrice;
int id, itemID;
infile.open("Data.txt");
infile2.open("ItemList.txt");
[Code] .....
The first customer shirt item isn't being outputted. Maybe I'm reading the or comparing the info wrong or just not seeing it.
I'm having a small problem on comparing a table i coded with a string that I want to input. I'm actually building a Bulls and Cows program and this is part of my assignment. What i want to do is to input a string and from the table get the results compared to the string i inputted.
Few words about the Bulls and Cows program.
The game involves two players, a coder and a cracker. The coder (either a person or a computer) chooses the four-digit number with all different digits and keeps it secret. The cracker tries to guess the secret number. After a guess, the coder gives you information about number of digits which were correctly guessed but in the wrong place (they are called 'cows') and how many are both the right digit and in the correct place (they are called 'bulls').
For example, if the coder chooses the secret number 0419 and the cracker guesses 6039, then the coder scores this as 1 cow, since 0 is a digit in the secret number that's in the wrong place, and 1 bull (9 is in the right place.)
what i want to do is when i input a string it scans the whole table of possibilities and gives me the results based on the string. so each row of my table is (let's say the secret code) and based on the given string(the guess) it gives me the result. Here's my table code:
Code:
void initialize(int poss[1296][4])
{
int i=0;
int j, k=0;
int m;

I have been working on code for quite some time and am able to successfully read in a text document and take certain words and information that I need. The issue is that I need to read in close to 100 plus documents and was wondering how I could read in the multiple documents. I thought about creating a structure of arrays and have each text document be an element and walk through taking each document but I am not sure how this works.
View 8 Replies View RelatedI'm working on a code that reads a text file and follows the instructions written in that file. An example of the text file:
*sum
11 4 61 2
1 2 0 14
17 99 1 1
*subtract
5 6 7
1 1 1
45 6 9
I want to read the text file line by line, each time I find an instruction (that is, the keywords *sum or *subtract) I want to make a summation (in the case of *sum) of all the numbers in each of the following lines, and repeat until the next instruction appear. So the text file above should generate:
78
17
118
-8
-1
30
That is:
11 + 4 + 61 + 2 = 78
1 + 2 + 0 + 14 = 17
17 + 99 + 1 + 1 = 118
5 - 6 - 7 = -8
1 - 1 - 1 = -1
45 - 6 - 9 = 30
how can I implement a dictionary(I'm guessing a dictionary is the best way to go here) so that when I read the string *sum i can call a function that does the summation of the following lines.
the size of the text file may be big (several mb) and the number of different instructions to search for may be in the magnitude of hundreds.

View 1 Replies View RelatedI'm currently trying to create binary file will not be able to be read as texts and will contain metadata(more like image files).
But I've tried writing to .dat, .bin files in binary mode and all of them are displaying in ascii text..which I don't want.
I am creating a simple log parser (loads a text file and filters out unnecessary information, but has the option to show the full log) and I'm running into an issue with fairly large log sizes (50+mgs). I have seen a few recommendations from a stream to memory manged files and even alternate 3rd party controls.
I foresee a few issues with any of the non-third party solutions (which I would prefer to avoid third-party add-ins) such as the scroll bar not correctly reporting the relative length or position of the complete text in the box (when displaying only a portion of the file at a time) and in the stream solution where you read on scroll (as necessary) have not only the same issues, but how do you resume reading in the middle of the file? This also all assumes I would be periodically clearing the RichTextBox to keep the memory usage down to avoid an OutOfMemoryException (which I have been running into.)
