So I'm really stuck trying to figured this bug on the program that is preventing me from displaying the text of my program..
#include <iostream>
#include <iomanip>
#include <fstream>
#include <sstream>

#include <stdio.h>
using namespace std;
int main () {
ifstream infile;
ofstream offile;

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];

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.
View 3 Replies View RelatedI 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.

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 am trying to write a terminal-like chat application in Linux. I would like to use a FIFO queue to print out the messages in terminal. The queue would be populated from 2 sources- stdin and messages sent from the other user over TCP. I have meet an obstacle that I cannot handle...
Lets say I would like to take user input using fgets and put it into a buffer. Then queue it if the buffer is not empty or print if it is. The problem is that when I use fgets or scanf, my input is instantly printed to the terminal..If i do:
Code:
fgets(message, 100, stdin); printf
("%s", message The string under message is printed twice :|. Is there a way to prevent this?

What I want to do is simple, however I can not find a way to do it in c++ and I don't know for sure that it is possible. I want to create a function that creates a simple short-hand for printf(x); Such as:
void echo(x){
printf(x);
}
But when I call the function:
echo "hi";//I want it to look like this
//instead of:
echo("hi");// like this.
Write a C++ program that does the following:
Prompt the user to enter a day of the week as M (or m), T, W, R, F, S, and U for Monday through Sunday respectively. The user may enter an upper or lower case letter.
When the user enters a character, the program will echo the letter and output the name of the day of the week.
Provide an error trap that reads something like "you have entered an invalid letter; program aborting." Suggestion: use a switch statement with the error trap as the default condition. it is not necessary to prompt for multiple inputs.
So I know how to get the program to echo back the letter and everything. What I am a little confused about is: will I have to define all the letters as their respective day? eg. make M== Monday. And if I do have to do that how would I get it to accept Upper and Lower case letters and recognize that that letter is == monday ect. ect.
Also my main problem is the switch statement as the error trap. I have never used the switch statement, but I know what they do. I just don't really understand how I would use it for an error trap. Am I suppose to just make a case for every other letter in the alphabet other then M T W R F S and U? Even if I do that then what if the user enters a number instead of a letter?

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?
I want to display a bmp file of resolution 600*420 (using c compiler like code block ) by manual loading. I tried to display the image by loading the pixel value. but this method has a limitation that it take up pixel value of image upto 64kb size.
So now i am trying to load it manually. What are the steps that i has to follow, what are the header files that i has to use ?
My system specification are windows xp professional , intel pentium 4 cpu. I don't know where to start ,does this method has any limitaton ,...etc ........
It's a shock to me seeing the partial display of variables being picked by intellisense. I am working in VS2013 environment. I have a project, in the project Settings file I created string variables of about 100 to be accessed across the files for the project, like this:
A example of thew variable it worked for
public static String TradeportAccordionSystemAdminInstitutionManagement = Settings.Default.[b]TradeportAccordionSystemAdminInstitutionManagement[/b];
An example of the variable it did not work for
public static String TradeportAccordionSystemAdminInstitution = Settings.Default.
So, does it mean that the Settings file has a limit of variables that should be declared in it?
I have a file in which I have written a structure called "Record".
Here is the struct definition:
Code:
#define IDSIZE 10
struct Record{
char id[IDSIZE];
int score;
};
Here's the code where I wrote to the file:
Code:
Record record;
char* id = "H12345678";
int score = 50;
record.id = id;
record.score = score;
file.write((const char*)&record, sizeof(record));
}
Here's a screenshot of the file in windows: [URL].... To the left is the id, 9 characters. To the right, well I'm assuming that's the score that I wrote.
And here's the problem, reading from the binary file:
Code:
Record record;
fstream file(argv[1], ios::in | ios::binary);
if(!file){
cerr << "Could not open the file." << endl;
return 1;
}
char* id = new char[IDSIZE];
[Code]...
The ID reads perfectly. The score...always returns 0, despite that it should show "50".
