C++ :: Read Multiple Text Files And Count Occurrences Of Word
Jun 8, 2013
I am supposed to read(scan) data from a folder with multiple(21578) text files, and file names are numbered from 1 to 21578,and read each word that occurs in a text file, and count the number of times it occurs in the entire folder,i.e; in all the files how do i go about it? I've tried this so far..but it isn't working..
I've been struggling with this for a while, I have to write a function that accepts a word (in my case the word is "the") and file pointer, and counts the number of times the given word appears (case insensitive) within the file associated with the pointer. This means the two words "the" and "THE" should both be counted.
Here is my code:
int WordCount :: countWords(string wrd) { int counter=0; string temp = ""; while (getline(*file,temp)) { for (int i = 0; i < temp.length();i++) {
[Code] ....
This is what I have come up with, but I get an incorrect value. It was suggested to us to consider using the strcpy() or strstr() functions, but I don't know how to use them.

I 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 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.
I have a .txt file that contains, together with a few characters, columns of values that I want to save in different files like is written in the program (file 1, file2, file3 - a with x, b with y, c with z). The pattern of the source text file is like this:
Until now I could manage to split the files, but the output gives me only zeros. First the program count the number of lines of the read text file, then it should display the desired columns of double values in three other .txt files.I've got for the three .txt files columns like this:
So im trying to create a quiz using c++ that incorporates three different types of questions. These are the standard one answer question, true false questions and multiple choice questions.
How to create the true false and multiple choice questions?
Ok here I have a program that reads a word from a text file randomly and matches it with the definition. The user has to guess what the word is according to the definition.
I'm having trouble with my for loop, I'm not getting any errors. But I just know something is off.
using namespace std; int main(){ int number; int count = 0; int numOfGuess = 0;
[Code] ...
This is words.txt:

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).

I have an EDI file whose structure is given below. This file has multiple records, each record contains a header (e.g EDI.DD.0000000001.20130809), then contents (i.e multiple paragraphs of text) and then footer (e.g End of Report/No EDI Activity). I have to read that entire file using regular expression using three groups.
I am using following regular expression to read the file.
That expression reads the "header" and "footer" in respective groups properly but didn't pick the contents between header and footer in "contents" group.
I have changed the font of header and footer in below file to understand the format. I am using asp.net 3.5 framework.

I have text (string) and I want to find a given word (it's ok!) and then insert another given word after the first word. The original string is beeing copied into a new string. But something is going wrong!!! Where is my mistake?
(I have some patches...)
Code:
#include <stdio.h> #include <stdlib.h> #include <string.h> //insert "new_word" after each occurence of "word" int main(){ char A[100]="In the sentence words the and the.";
I'm using multiple C++ files in one project for the first time. Both have need to include a protected (#ifndef) header file. However, when I do that, I get a multiple definition error.
From what I found from research, adding the word inline before the function fixes the error. Is this the right way to do this, and why does it work? Should I make a habbit of just declaring any function that might be used in two .cpp files as inline?
I am writing this program that is supposed to read a file, put the data into an array, alphabetize, count how many times each word appears and print to an output function. I posted before on how my program had an error when I ran it but I have fixed that. Now my outputArray file is empty. It gets created but there's nothing in it.
I have to develop an application that uses Qt, Excel and live-time file checking. My client gave me this:
I have a problem at work. I need you to develop this: I want one application with GUI (it said windows), that generates an report for each sheet (employee name) in the file, with the columns. I don't want to make the computer slower, so check the file and get the name of the employee that is altered and only change his report
How to start it. All Excel libraries I use stop working on my computer and this "File Checking" is other trouble, because if for each second I compare the size of the "old" file with "new" file, the memory will explode.
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?
So I'm trying to complete this part of a program where I have to read a text file from Stdin and add it to the 'word list' wl. I get how to read from a text file but I don't know how to go about adding 'words' to a list, if that makes sense. So here's what I got:
Source is an array that determines how many words are read from the text and length is the amount printed on screen. Here's the program I'm writing the implementation for:
4.1 Write a program that will count from 1 to 12 and print the count, and its square, for each count.
4.2 Write a program that counts from 1 to 12 and prints the count and its inversion to 5 decimal places for each count. This will require a floating point number.
4.3 Write a program that will count from 1 to 100 and print only those values between 32 and 39, one to a line. Use the incrementing operator for this program.
How would one go about doing this? I am very fond with Windows I/O, but not so much with this subject. I am decent with fstream, probably not as skilled at it as I should be, but I assume <fstream> would be a better choice, since it isn't locked to Windows.
Anyway, say I have a .txt file like this:
Bill is a cow. Bill likes meat. Bob is a pig. Bob and Bill are friends.
And I want to count the number of times "Bill" is written. How would I do that?
I'm trying to code a program to read the user's input and have it:
-count vowels -stop counting vowels after '.' or '?' (ie. abcdjwef is 1 a, 1 e; while fje.fwdfeiii is just 1 e) -closes when ENTER is pressed after a '.' or '?' is found (ie. closes after 'abacds. ENTER' as well as 'as.fefsdf ENTER') -display the number of vowels
Is there any way to do this with only 'cin >> userInput' and a while loop checking for punctuation?
