C/C++ :: Compare Words From Text File With Array?
Apr 16, 2014
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;
[code]...
the test variable in the last for loop is wrong i know i was just trying something.

I am trying to read in player names (ex: first last) from a text file into the people[].name data struct. I can successfully read in my card file, but I cannot get this to work. I get a seg fault. I believe this is because nothing is actually being read in for my while loops. I can't use std::strings so these must be c-style strings aka char arrays.
// deck of cards
// below are initializations
#include <iostream>
#include <fstream>
#include <ctime>
#include <stdlib.h>
#include <string>
using namespace std;
//globals
const int maxCards = 52;

I have a program I have to do that counts the number of words in a text file. I have tried the code on 2 computers now since my programming teacher told me the code was fine. Here is my code:
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
int main() {
ifstream infile;
infile.open("tj.text" , ios::in);

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?

I'm trying to make program that will read text from a file and show what words occur how many times. I'm trying to make it so that if a new string comes, it saves it into wlist[], and counts 1 to wcount[]. If the same word is there, it will just add 1 to wcount[]. The program will end when it gets to the end of a file.
I don't know the reason, but I can't get strcmp and strcpy to work. I had to put a pointer in curword, just to make it compile.
Code:
#include <stdio.h>
#include <string.h>
#define LIST_MAX 100
#define WORD_MAX 20
int main(){

I am trying to generate possible combinations of 4 lower case letters from aaaa - zzzz. The words will then be used against a file that contains encrypted passwords that each relate to a 4 lower case word. I have successfully generated the words. Now all i need to do is put the created words (aaaa, aaab, etc...) to an array so I can use crypt((array[i+1]), buff) and print the encrypted 4 letters that come from the file. I am having a lot of trouble complete this though.
New problems that are occurring
The main problem is in the all function and main. I'm not wanting to print the aaaa, aaab, aaac, etc to the screen but I want to put it in an char array so that i can compare each individually to each line from the file using crypt. How to put all 456976 combinations into an array, compare it to each line of code, and print the solutions to the screen.

This what I'm trying to do:
Type two or more lines of text into a file. Write a program to open the file, reading each word into a vector<string> object. Iterate over the vector, displaying it to cout. That done, sort the words using the sort() generic algorithm
But I'm stuck unfortunately.
#include <iostream>
#include<fstream>
#include<vector>
#include<cstdio>
using namespace std;
int main() {
ifstream infile("about.txt");
[Code] .....
Error: 'about' was not declared in this scope

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.

This is my text file.
bak kut teh[tab]888.0[tab]989.0
spicy chicken nugget[tab]999.0[tab]978.0
I'm experiencing some problem in trying to scan and put it into an array for the food names (e.g an array for food which consist of bak kut teh and spicy chicken nugget) and another 2 array for the other individual integer into C. However there seem to be some problem with my code.
Is there a difference if I use both tab and space instead of space for all?
Code:
#include<stdio.h>
int main() {
FILE *fp;
char food[100];
char buff[BUFSIZ];
float num;

I have this program for class where we just need to show that we can read, write to a text and binary file. We also need to populate an array from both a text and binary file. When the user first runs the program, the user is told that text/binary file does not work for reading because they do not exist. The user is then asked to start inpuyting integers into the console and at the same time creating and appending to a text/binary file. These values are also stored into an array as they are being inputted. Later in the program the array is run through a for loop and displayed to the screen. Displaying the array to the screen works fine here.
My problem is when the user runs the program for a second time. The text file is opened and an fgets is run to populate an array based on the numbers in the text file. That array is then used again for the user input and file writing section of the program. When the array is displayed at the end of the program the numbers do not make sense. Some appear to be correct bu most do not. When I do the similar actions to the binary file there is no problems. The text file is amended properly everytime the user runs the program. userInputText[MAXSIZE]is a char array (MAXSIZE is defined at 100000) and both textCount and textCounter are initialized to zero when the program is at this point.
Here is what the code where I believe the program resides. I have also attached the source file.
Code:
textPointer = fopen("textFile.txt", "r");
if (textPointer) {
while(fgets(userInputText, sizeof(int), textPointer) != NULL){
sscanf(userInputText, "%d", &textCount);
userInputText[textCounter] = textCount;
textCounter += 1;
}

Reading in a maze into a 2D array. The first two reads will give me the dimension of the maze(ex. m x n maze). So in order to create the 2D array i need the first two reads. Then after it is created it will read the rest of the data which are 1s and 0s. I have to create a program that will solve the maze but i cant test my movement code if i cant read in the data first. the entire program compiles but to test if i read the file i have a function to print it. But it says "There are: 0 rows and 0 columns " so it didn't read anything since rCount and cCount are initialized to 0. and basically the maze has nothing in it.
Code:
#include <iostream>
#include <fstream>
#include <stack>
#include <cstdlib>
#include "position.h"

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].

I am at a loss with an assignment. I am supposed to read from a text file, with an input of something like this: alphaproleone,stroke,42 1 and Store it into an array of structures and then output it with each word/number starting on a new line. My current code prints out only the first part, and the "a" in alphaproleone is the actual number "21".
#include <iostream>
#include <string>
#include<fstream>
#include<iomanip>

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

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.

I have a program that saves all information temporarily into memory (into the array), however, I need a permanent save solution. I have the full program working correctly, formatted perfectly, but it's missing the file array to file output.
Essentially, whenever I'm presented with the menu I'll be able to add entries, search by last name, show the entire list, and exit and save. Whenever I select option 4 the program should save to a file "address_book.txt". Whenever I reload the program, it should load from "address_book.txt" and populate the array with the preexisting data.
My question is focused on how and where I should implement the file output. What I have thus far:
#include <iostream>
#include <string.h> //Required to use string compare
#include <fstream> //Eventually used to store array into file
using namespace std;
