Aug 2, 2014
read a text file and store the file contents into a 2D array?
100 101 102 103 104 105
106 107 108 109 110 111
112 113 114 115 116 117
118 119 120 121 122 123
124 125 126 127 128 131
Here's my code:
const int ROWS = 5;
const int COLS = 6;
int array[ROWS][COLS];
ifstream inputFile;
inputFile.open("table.txt");
[code]....
When i run the program and try and display the array, it doesn't work.

I am trying to store the contents of a text file into a char array. However the function i am using ifstream member function get(); seems to stop working when fed with certain characters. Is there another solution besides the get() function that will accept all types of characters from files?
char text[1000];
for (int i = 0; i <= textlen; ++i)
{
text[i] = text_in.get();
}

I have written the following code but i am stuck. Write a program that will prompt the user for a file name and open that file for reading. Print out all the information in the file, numbering each new line of text.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include <ctype.h>
int main()
{
char line[81], filename[21], c;
int i = 1;
FILE *inFile;
[code]....

how I can read information from a text file into an array so afterwards I can display the array and it will show the contents of the text file?
the information inside my text files consist of names and numbers like so: "Collins,Bills 80" should I separate the numbers and names into two separate text files one for names and one for numbers?
My code so far is this:
#include <iostream> //for cin and cout
#include <fstream> //for input/output files
#include <conio.h> //for getch

So I am working on a FUSE filesystem and I currently have the need to load the contents of a text file into an array.
My array initialization looks like: char array[max_entries][PATH_MAX] = {NULL}
The reason I want to pass it by reference is that I want my function to return two values essentially. One a specific char* and the other an array like I initialized. My function proto type looks like:
char* load_meta(char* list[max_entries][PATH_MAX], char* path, int mode);
How I'm trying to call the function:
someChar = load_meta(&array, path_name, 1);
Within the function I try to edit the array by deferenceing it once, like this:
strcpy(*list[i], file_entry); // This seg faults

Goal:
Read contents from a file and use as the size of a 2d array.
Problem:
C2087: Line 27 : "a1" : missing subscript
C2133: Line 27 : "a1" : unknown size
Code :
int rows;
int columns;
ifstream fObject("inputdata.dat");
fObject>>rows;
fObject>>columns;
char a1[rows][columns];
I am not sure why this is occurring, or if there is a better way to do it.

I'm coding a hangman game. I'm trying to store user entries so i can output them to show the user what they have already entered. Problem is that it's not display anything at all.
I'm trying to store multiple characters of course, and then display all characters stored.
char guess[27]={0};
cin >> guess[26];
int hit=0;
for(int i=0; i<len; i++) {
if( guess[26] == hidden_word[i] ) {
hit++;
select_word[i] = guess[26];
if(strcmp(hidden_word,select_word) == 0) {
[code]....
EDIT: I also get the error - Stack around the variable 'guess' was corrupted. At the end of the game.

I want to read the contents of a file block (512 bytes) by block using low I/O read statements. Each record is 64 bytes long and has a pre-defined structure. The first 4 bytes are an unsigned integer; the next 20 bytes are ascii text, etc.
I have a buffer which I can access with buf[0] to buf[63] to read the first record and then buf[64] to buf[127] for the second, etc. However, I was wondering how to map a record so that I can refer to an integer as an integer and a float as float, etc. I can't create a struct and move the 64 bytes to it, as I will have alllignment/padding problems.
What is the standard way to deal with records in C?

In a program, I have a text file (called MyDictionary.txt) which has thousands of words in alphabetical order. I need to make a C program that reads in this text file and then makes an array called char Words[# of total words in the text file][length of longest word].

Perhaps my original wording on this was confusing so I will ask a different way.
if I have a text file called
data.txt
and it has the following in it.
12345
67890
12345
67890
how would i read this information into an array called
int data[4][5]
This is in C.

Code:
#include <stdio.h>
#include <stdlib.h>
int main (int argc, char *argv[])
{
char buffer[256];
FILE * myfile;
myfile = fopen("read.txt","r");
[Code]...
I also got an error in printing wherein the data in read.txt is "Hello" newline "World" and my program prints world twice.

I am suppose to make a program that reads in data from a text file (integers only) and sorts them as it inserts them into an array of size 10. I did this using an insertion sort, which worked great. But now I am being told that I need the function has to read ALL of the numbers in the text file, not just the first 10, and I am not allowed to store them THEN sort, it has to be sorted as being stored.
This is what I have for sorting first 10
void sortArray(int iArray[])
{
string fileName = "";
fstream inFile;
int tmp = 0;
[Code]....

I'm making a program in which it will read an input from a text file and then count the numbers of spaces , characters , words . Here is what i think it would work : First i will transfer the contents from the input.txt into a string , after that i will create 3 strings which contain each of these : spaces , characters , words . Then comparing each of the contents of the intput.txt_string to the other 3 strings .
#include<iostream>
#include<fstream>
#include<string.h>
using namespace std;
[code]....
and of course it doesnt seem to work...

I've created a text file with the numbers from 1-450. After writing code to retrieve and print out the contents in the text file, the compiler only printed out the numbers 124-450. Is there a reason why this is happening?

I want the user to enter the word and I want to check if it exists in a text file or not. I tried
int flag=0;
char word[50], input[50];
cout<<"Enter word to search for";
gets(input);
[Code] ....
But it does not seem to be working. Should I make changes to it or is there another way?

am trying to create a service that will try to create a service that will monitor a folder. Whenever a new file gets created, I am trying to read the contents of new file and copy contents (with same file) at a new location.
The problem I am facing is that only first file that gets its name copied and a file created at a new location, but without any contents. The subsequent files do not get created at all.
My Services.cs looks like this:-
public partial class Service1 : ServiceBase
{
public Service1()
{

This is part of my code. what i wanna know is if there is a way to fill this array until the text is over instead of having to set the number of strings in the file (20). And then store that number into a variable.
int main() {
//array:
string words[20];
//file to open:
ifstream file("test.txt");

I need to store the last 3 deposit that I have in my deposit. I have few option but i dont which would be easy
1.Store all deposit to the text file (store always in a new line), and display the last three deposit from the text file.
dep 1 - 60
dep 2 - 40
dep 3 - 100 print 100
dep 4 - 50 print 50
dep 5 - 50 print 50
2. I think this option is more difficult, when it reach deposit 4, to get rid deposit 1
So when i make a deposit 4, the deposit 1 get's ride
dep 2 - 50
dep 3 - 100
dep 4 - 70
Right now i can only display one deposit (last one), then i close the program and run again and i make another deposit it overwrites a new deposit.
My code.
To show sure my deposit that has been made.
double depSave () {
int option;
float dep1,dep2,dep3;// Declare your variables
dep1 = dep2 = dep3 = 0; // Set them all to 0
system ("cls");
string path = "deposit.txt"; // Storing your filename in a string
[Code] ....
Where is says "save deposit" in comment that where it saves to the deposit text file, that going to be output to the depSave function.
