C++ :: How To Load Contents Of Text File Into Array
May 12, 2013
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:
1. Load HTML File (or take stuff from string) 2. display window with content of that html
so yeah, basically something like a browser, is there some lib that will just load html and do it for me? I dont need whole browser, I just need to show really simple html pages in my app....
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 a group assignment were we need to load sokoban levels from text file. We have loaded the file in a vector but how we can parse the file for it to be used during the game.
We read about malloc and know how to access each character from the vector, but how can we select a particular level after the user inputs an the level integer number?
I am doing an exercise that reads in a text file and loads the data into a struct. My problem is it doesn't read anything from the text file. I think it's the way I'm loading the data. Oh, it does read in the first record that tells the program how many contributor records to create, but nothing after that. Here it is:
Code: // #include <iostream> #include <fstream> #include <cstdlib> const int strsize = 30; const int SIZE = 60;
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;
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 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;
I wrote a program to write text contents to file stream through fputs, the file stream address was changed in the middle of writing text content to the stream (11% text content have been put into the file stream), that cause the file stream pointer can be evaluated problem and raise exception on stream validation code in fputs library function, my question is what things could go wrong to make file stream pointer changed its address to something else or a NULL pointer if the file stream have not been flushed and closed.
Let's say I create a small program or just want to open any kind of file on my computer, but I want to run a program that forces the user to enter a password or something (I already know this part). How does one create the code that would open the file?
How to load .wav files. Say there are several .wav files in a folder called "sounds" in "My Documents", what would be the steps on loading them in a vector or array. I'm thinking I should use a vector type of array to not worry for a fixed size.
i have made this first level in this ascii game, and i realized that if i want to continue, i must rewrite the switch statement and write thousands of lines of code. how can i load a map from a txt file?
#include <iostream> #include <windows.h> using namespace std;
I'm working on a project, and I'm trying to fill in various vectors from a given input file. The input file looks like:
<catalog> <book id ="bk101"> <author>O'Brien, Tim</author> ....etc
My load vectors function looks like this: void load_vectors(vector<string>&id, vector<string>& author...etc)
I can't assume a limit on the number of books etc listed in this catalog, so I'm using the eof() function. However, I don't know how to write the loop to gather the correct strings and place them in the vectors.
Code: while(in.eof()) { string text; int index, index2; getline(in, text); int index = text.find("<author>"); int index2 = text.find("</author>"); a = index.lenght(); author.pushback[i] = text.substr(index + a, index2); }
This seems like a fairly straight forward assignment. Load up a file that contains a series of int values stored in ASCII and print out the ASCII characters to the console.
The problem I am having is that I am getting the numerical value of bytes ("40" for 10 numerical values, "200" for 50 values). The numbers are generated randomly by another file, but I can control how many numbers are generated. For example, if I type in:
I have done a test, I have edited with the WordPad in Windows on my Local Webserver a file banana.h which contains a list of float arrays in order to extract one array and create a text file named ObjVerts.txt I have done a lot of search in the Web in order to find a small piece of code that can read the text file and convert it to a float array GLfloat, but I did not find any. I have found a lot of piece of code that read the file and make a NSData but many of the code seem to not work. It seem that the last statement return nothing!
I know to read a strings into array and tables.. what is they are mixed up?? strings are just names ( 3 characters) and there are bunch of table.. the max size was set to 60
ex. text file
JES DAN JEN . . . 01010101 10010101 RAM JET 01010010 10100101 .... and so on
I'm writing a program that stores records into a file and then these records can be printed out. A last name, first name, and score is stored to be exactly 36 characters long (using leading spaces to pad) making it easier to retrieve specific records. For example, three records stored in the file would like like this: (the underscores are simply to illustrate the distance, they are not in the file itself)
When printed out, the names are formatted as follows:
lastname, firstname: 90 lname, fname: 100 last, first: 60
However, when I print them out this is what I get:
lastname, firstname: 90 lname, fname: 100$ last, first: 60H
For some reason, for any record after the first, an extra character is added to the end. These characters are not in the file, so I was thinking that the array for some reason wasn't being filled completely, (the array is initialized to size 36 and 36 characters are read from the file using fread) so it was printing out a random character assigned to the 36th array position. Except the character never changes, (always a $ for record 2, H for record 3, l for record 4 if i remember) and I've tried reducing the array size or the number of character read and it's the string that gets altered, the random character always remains. I figure the problem must be in the print_records function (appending seems to work no problem). Anyway here is my print records and appending records code.
Code: /* - Prints a single record stored in the file pointed to by ifp. */ void print_record(FILE *ifp, int record) {
I am writing a code with C where I will give an integer and get the binary conversion of it.I tried to fill the binary digits into an integer array.But when I normally print it will give the proper output.But when I try to print the contents of the array it will not produce the proper result.
I'm trying to reverse 25 items that are in my array by using a For Loop and sending 2 of the numbers to a function at a time. The code I have right here, is not working at the moment, I cannot find the problem because i've been staring at my code for too long.
int farEnd = 24; for (int i = 0; i < 24; i++){ Swap(intArray[i], intArray[farEnd]); farEnd--; }
I was given an assignment on outputting the number of upper and lower case vowels from a text file. I was provided guidelines, but I'm still very new to arrays. how:
1. The values would be sorted into the array 2. To correctly output the array. 3. What information seems to be missing.
