C++ :: Reading Two Words Into Single Char Array From Text File
Sep 15, 2014
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;
[Code] .....

I have a project which is about linked lists in the order of: a Story is made of Paragraphs which is made of Sentences which is made of Words. We must treat Words specifically as character arrays, not strings. So I need to read in a story from a text file and make Words by finding the first whitespace/punctuation(everything before the whitespace up until the whitespace or punctuation is the Word), all the Words up to the punctuation are a Sentence (Sentence is a linked list of Words), Paragraph is all the Sentences up until an empty line, and a Story is all the Paragraphs. So I know doing this will let me take a line and put it into a character array:
char charArray[25]; //we are allowed to assume a word won't be longer than 25 characters
int i = 0;
ifstream myFile(fileName.c_str());
if(myFile.is_open()){
[Code].....
I suppose I could look at charArray[i] and if it is ws or punctuation then make the Word = charArray[i-1], but is there an if statement I could do that would prevent the ws or punctuation from being read into charArray in the first place? Because a problem I see with the charArray[i-1] method already is that "This is a story." would get put into the array as Thisisastory. and thus I'd be unable to break up at a space.
So to summarize: I want to read in a text file character by character into a char array, which I can set to length 25 due to context of the project. I want to read in each character and at a whitespace or punctuation, I want to take everything already in charArray and feed that into a Word object constructor (the next Word gets linked to the previous Word, and at a punctuation all the Words linked together become one Sentence, and all the Sentences linked before an empty line become a Paragraph, etc). So how can I get charArray to be only characters in a word, then after the word being read-in ends, charArray resets to empty, and then is populated by the next word and so on.

I am trying to concatenate two words from a file together. ex: "joe" "bob" into "joe bob". I have provided my function(s) below. I am somehow obtaining the terminal readout below. I have initialized my memory (I have to use dynamic, dont suggest fixing that). I have set up my char arrays (I HAVE TO USE CHAR ARRAYS (c-style string) DONT SUGGEST STRINGS) I know this is a weird way to do this, but it is academic. I am currently stuck. My file will read in to my tempfName and templName and will concatenate correctly into my tempName, but I am unable to correctly get into my (*playerPtr).name.
/* this is my terminal readout
joe bob
<- nothing is put into (*playerPtr).name, why not?
joe bob joe bob
seg fault*/
/****************************************************************/
//This is here to show my struct/playerInit

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.

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 am trying to read strings to an char array from an .exe file and then i would check some of the strings, but the problem is that the only thing that is read from the file is the first string (MZ) and an 'square' that is some incorrect character. I am using fread to read from the file. Here is my code:
FILE * pFile;
long lSize;
char * buffer;
size_t result;
pFile = fopen("my_file.exe", "rb");
if( pFile == NULL) exit(1);
fseek(pFile,0, SEEK_END);
[Code] ....
(I want to read the whole file, its not that big)...

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"
[Code] .....

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();
}

int end, beginning = 0;
string word;
string line;

General Purpose: Delete all "white spaces" in text file, until the read-in char is _not_ a whitespace (mark as start of text file).
Problem: Cannot seem to shift char's over properly. (I think my problem is the inner loop - however other code may lead to this problem - I do not know)
Code:
#include <fstream>
#include <iostream>
using namespace std;
bool trimWhiteSpace(fstream &file, char * charMemoryBlock) {
if (!file.is_open()) {

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'm writing a code which has to read a text from a file. In this text, there are some symbol and numbers (ex, This is $19 of....). Those symbols and numbers should be replaced with the words from the other file. i.e.
transformed file
This is just an $19 of what the $5 should obtain.
And $19 should be replaced from association file
19 example
5 program
The result:
This is just example of what the program should obtain. I'd like to save the first file content into an array of strings and the same for the text of second file.
