C :: Displaying A String Loaded From A Text File
Jan 19, 2014
I'm working on a program that can load all words from a dictionary "English2.txt" (it's attached to the post), then put every word into a 2-dimensional matrix (every line is reserved for one word) and display them. After loading every word into a matrix, when I try to display first 8 words with printf, I can't do it without '' at the end of a line. Otherwise only the 8th word is displayed... What's more, when I try to read the length of the first word with strlen, it says, that it has 4 characters (in fact there are only 3 and it's the word "AAA"). What could be the reason for that?
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <stdint.h>
int main()
{
FILE *fp;
char buffer[32];
[Code]...

Is it possible to display data from a textfile and also save data in to a textfile, reason being is for me to create back-ups of data into a textfile hidden somewhere in a safe location in the local disk or server in case of database error and failure.

I have a text file that is divided into blocks:
#1
1:animal
2:food
3:moves
4:oxygen
#2
1:eats:2
2:breaths:2
3:can:1
4:is a:1
#3
1:1:2
1:3:3
1:2:4
And the following program that displays block by block:
StreamReader streamReader = new StreamReader("G:LAB123LABWORK2.txt");
int block = 0;
while (!streamReader.EndOfStream) {
string line = streamReader.ReadLine().Trim();
if (line.CompareTo("") == 0)
[Code] .....
My problem is am supposed to add a verification code so that if i put a string e.g 1:?:? it returns the block where the string is found and gives of all possible answers.
Attached Files : LABWORK2.txt (240 Bytes)

I'm making a very first program. It's very little more then a simplistic calculator, but i'm having a problem with the cout function. It won't display any text what could the reasons be?
#include <iostream>
#include <string>
#include <sstream>
using namespacestd;
int main () {
do {
int(a);
[Code]...
Oh and i'm aware it's still riddled with numerous problems, I just have been working on the cout thing first.

How to get a txt Outfile to display a Checksum.
Code:
ChecksumFileDisplay = fopen(ChecksumFileDisplayPath, "r");
fprintf(ChecksumFileDisplay, BigEndianChecksum);
That's what I have but it doesn't like the fprintf function because BigEndianChecksum is an unsigned int and it wants a pointer to a const char. Is there a function similar to this that will display an 8 digit integer in a txt outfile?

Provide three menu options to format the text entered in QTextEdit to
(1) display the letters in capital letters
(2) display the text in red
(3) align the text in the center
I did the 2nd and the 3rd part but I can't find the capital letter part
Code:
if (name == "Color") {
textEdit->setTextColor("red");
}
if (name == "Capital") {
textEdit->??????;
}
if (name == "Center") {
textEdit->setAlignment(Qt::AlignHCenter);
}

I'm trying to make a program that will read in names and grades from a text file and print them in the console. However whenever I try to use the OpenFile.get function I get an error saying that there is "no instance of overloaded function"
getting this error resolved before I can.
my code so far (I know it's missing a lot, but that's not what I'm worried about right now.)
#include <fstream>
#include <iostream>
#include <string>

I need to read from a text file and search for a string that appears in the file and then count how many times it appears. My count just prints zero though. Do you see what I did wrong in my code for this to happen?
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

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'm trying to read all content from a text file into a string. This is the code I'm using for it (I know there are other, maybe better ways to do it but I'd like to stick to this for now):
char* buffer;
std::string data;
FILE* fp = fopen("textfile.txt", "rb");
if (!fp) {
printf("Can't open file");
[Code] ....
So my problem is that I get an exception when I try to free the memory -> 0xC0000005: Access violation reading location 0x51366199
I even get the exception when I try to free it immediately after calloc() but why this is.
And if I use buffer = (char*)malloc(lSize); I don't get any exceptions.
So, why this fails and what I'm doing wrong.

I want to input a string, say: abcdaa so, the program should output:
a
b
c
d
In other words, the program will display each character for only ONCE!!!! And display their frequency. Here is my idea: user will input a string and such string will be copied into another string variable called "checker".There will be a loop and each character will be printed, BUT, first, the program will check if the character to be printed is not equals to all elements of the checker string.
I already have the function to count the frequency of each character
GOAL: to make a program that will accept a string and use the HUFFMAN CODING to compress it.
for(x=0; x<string_in.size(); x++) {
cout<<" "<<string_in[x]<<endl;
for(y=0; y<string_in.size(); y++) {
if(checker[y]==string_in[x])
break;
else
checker[x]=string_in[x];
}
}

I have two puzzling issues I am dealing with.
Issue 1: I am using a stringstream object in a block of my program that needs to be visited repeatedly depending on a user's selection from a menu. I want the contents of this stringstream object to be cleared any time control gets to this part of the program. I have tried the clear and flush functions to no avail.
Issue 2: I am reading data from a source text file that would be regularly changed during the course of program run. After the program run is over, I am supposed to save the results(which is basically the source text file AND all updates) in a destination file. This destination file would then serve as the source file when next the program is run. In other words, I want a scenario where my results overwrite the original contents of the source file; implying that my source and destination files are now one, pretty much. How can I do this?

I am trying to print a specific line from a textfile
e.g
I have a text file called info.txt and inside it contains the id,item name, price, quantity
Code:
1,shirt,100,10
2,pants,50,9
3,pen,20,8
I know how to find a specific word at the line in the file but how do I find and print out the specific line e.g(print out just the entire contents of line 2)?
Code:
string temDescription;
ofstream fout;
int curLine = 0;

I've tried a bunch of alternative methods to prevent an assertion error. "not understanding" the bug and why I'm getting it are relevant here, not proper, (or more appropriate), coding methods. I would write it in another way to prevent the error, I simply want to understand what is happening during run-time that causes the situation.What is the bug?
---------------------------------------
[assertion error]
[expression _block_type_is_valid(phead->nBlockUse)]
--------------------------------
Code:
#include <iostream>
#include <string>
using namespace std;
int main() {
cout << "Enter your name : ";
string Name;

I've a problem here...
#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <conio.h>
#include <string>
#include <iomanip>
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
[Code] ....
The program needs to be able to read the middle names within the text file named Info2.txt
Simply adding the Mname or any related value where the other to name values doesn't do anything and only the 1st line appears on the output.
Don Jon111012
Jack Bo Todd151015
Jill Jo Jane161011
Bob Jack Chuck 131513
Da Fu111012
That is the correct way it appears in the text file. Also I know it's commented out, but that just to keep the program from crashing.
current output
Survey Results:
Name Results
Don Jon 33.00
This is the Info1.txt file info by the way.
Ken A202017
Gus B151015
Bill C151512
Jara C151720
Lu E101510
Chow B171015
And the output

Name Results
Ken A 57.00
Gus B40.00
Bill C42.00
Jara C52.00
Lu E35.00
Chow B 42.00
Which when ran with Info1 selected, it is the correct output I'm looking for. I've tried getline and other solutions and they didn't work.

If I create a file that looks like this for example,
car 2 4 6 8
truck 1 2 3 4 5 6
plane 4 5 6 7 9
Whenever I go to open it back up like this,
ifstream inputFile;
string line;
inputFile.open("file.txt");
while (inputFile>>line) {
cout << line << endl;
} inputFile.close();
return 0;
}
It displays output like this,
car
2
4
6
8
How can I get it to display like above?
