Visual C++ :: Error When Trying To Read A Random Word From A File
May 8, 2015
I am currently writing a password generator in Microsoft Visual Studios 2010 Professional. The section I am having a problem with is the practical password. It is suppose to randomly read 3 words from a text file and then display it in the text box. The program will compile and run but when I hit generate I get "True True True" and not three random words. Then this warning shows up:
Warning C4800: 'char *' : forcing value to bool 'true' or 'false' (performance warning)
//Code is from the form1.h file. I can post the rest of the code if need be but I just included my includes and the problematic section
Code:
#pragma once
#include <cstdlib>
#include <ctime>
#include <stdlib.h>
#include <cmath>
#include <iostream>
#include <iomanip>
[Code] ....
Screenshot of the warnings: [URL] .....
Picture of the output: [URL] ....

How would one go about doing this? I am very fond with Windows I/O, but not so much with this subject. I am decent with fstream, probably not as skilled at it as I should be, but I assume <fstream> would be a better choice, since it isn't locked to Windows.
Anyway, say I have a .txt file like this:
Bill is a cow.
Bill likes meat.
Bob is a pig.
Bob and Bill are friends.
And I want to count the number of times "Bill" is written. How would I do that?

Ok here I have a program that reads a word from a text file randomly and matches it with the definition. The user has to guess what the word is according to the definition.
I'm having trouble with my for loop, I'm not getting any errors. But I just know something is off.
Here's my code:
#include <iostream>
#include <fstream>
#include <string>
#include <cstdlib>
#include <ctime>
using namespace std;
int main(){
int number;
int count = 0;
int numOfGuess = 0;
[Code] ...
This is words.txt:
apple#the usually round, red or yellow, edible fruit of a small tree
boat#a vessel for transport by water
horse#a solid-hoofed plant-eating domesticated mammal with a flowing mane and tail, used for riding
television#a system for transmitting visual images and sound that are reproduced on screens
soup#a liquid dish, typically made by boiling meat, fish, or vegetables, etc.
bottle#a container, typically made of glass or plastic and with a narrow neck
barber#a person who cuts hair
toast#sliced bread browned on both sides by exposure to radiant heat
radar#a system for detecting the presence, direction, distance, and speed of aircraft, ships, and other objects
red#of a color at the end of the spectrum next to orange and opposite violet

I have program that is supposed to read in a story from an input file and separate the words and output the lines on which the word occurs. It needs to read in another input file that has a list of words (1 per line) to ignore. i.e. skip them when running through the story. This is what I have so far, I've changed multiple things trying to get it running....
#include<iostream>
#include<fstream>
#include<map>
#include<set>
#include<vector>
#include<string>
#include"split.h"

I need my program to read a list of numbers from and input file, random.txt, and calculate the following statistics on those numbers:
A. The number of numbers in the file.
B. The sum of all the numbers in the file.
C. The average of all the numbers in the file.
D. The largest number in the file.
E. The smallest number in the file.
#include <iostream>
#include <fstream>
#include <iomanip>
#include <string>
[Code]......
This is what I have so far but I'm not sure if it is right. I can't get the input file to open.

The user will first enter the file name to be processed. The program can do the following 5 tasks:
1. Count the number of words
2. Count the number of alphabets (without punctuation marks)
3. Count number of sentences.
4. Count the frequency of each vowel.
5. Count frequency of the following three words individually: FAST, computer and engineering
There should be a proper menu through which the user can select the desired task. The program should continue until the user asks to terminate it.
Here is what i have done so far:
#include <iostream>
#include <cstring>
#include <fstream>
#include <cstdlib>
using namespace std;
int main(void)
{
int opt=0; //option number
ifstream fin;
string filename;
[Code]...
There are a few problems.
1- When I enter option 'q', an infinite loop starts.
2- The first time, the program gives the correct value. After that, each time it gives answer ZERO.
3- The last part is not working. I experimented something which failed. I don't know how to do the last part.

I just can't seem to get this right. What I want to happen is when the program runs a random word should pop up.
I have included my code. I'm not sure by putting tag around my code.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;

I am trying to use struct to store variables from a text file and use them in the main program. I have first tried running the program without using struct and declaring the variables within the main program and it runs fine. But after using struct, it gives no compilation error and a segmentation fault as output. Also, if the size of file/variable size is unknown can I declare variables as char string[]??
The code is as below:
Code:
#include<stdio.h>
struct test {
char string1[10000];
[Code].....

Basically I have a text file called words. I'm supposed to extract a word randomly form the file and have the user guess the word. If they guess the word correctly in x number of tries they will receive the definition.
I'm having trouble receiving that random word and I'm getting the definitions from the file.
Here's my code:
#include <iostream>
#include <fstream>
#include <string>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
using namespace std;
[Code] ....
This is what is in the words.txt file
apple#the usually round, red or yellow, edible fruit of a small tree
boat#a vessel for transport by water
horse#a solid-hoofed plant-eating domesticated mammal with a flowing mane and tail, used for riding
television#a system for transmitting visual images and sound that are reproduced on screens
soup#a liquid dish, typically made by boiling meat, fish, or vegetables, etc.
bottle#a container, typically made of glass or plastic and with a narrow neck
barber#a person who cuts hair
toast#sliced bread browned on both sides by exposure to radiant heat
radar#a system for detecting the presence, direction, distance, and speed of aircraft, ships, and other objects
red#of a color at the end of the spectrum next to orange and opposite violet

My professor wants me to write a program that will read from a dat file, and produce an output on the screen based on the file. I don't understand why I am getting this error. I suspect it has something to do with the number of characters I've told it to read.
#include<iostream>
#include<iomanip>
#include<fstream>
#include<assert.h>
#include<string>
using namespace std;
using namespace System;
struct TStudent {
string month[10];
[Code] .....
I noticed I had a 2 beside girl, after I removed it, it still didn't fix my problem.

I am currently using Flash. Here are two images I will be referring through without this post:
1: [URL] ....
2: [URL] ....
So basically, when I click the generate buttonon the first image it takes you to the second image. What I want is when I click the generate button it comes to this screen, aswell as choose a random word from each list that I will make (Who List, What List, When List, Where List, and Why List) and place the word next to its position. When you click New Idea I want it to also generate another set of random words from the lists. How can I do this?

Goal:
Read contents from a file and use as the size of a 2d array.
Problem:
C2087: Line 27 : "a1" : missing subscript
C2133: Line 27 : "a1" : unknown size
Code :
int rows;
int columns;
ifstream fObject("inputdata.dat");
fObject>>rows;
fObject>>columns;
char a1[rows][columns];
I am not sure why this is occurring, or if there is a better way to do it.

So I'm trying to complete this part of a program where I have to read a text file from Stdin and add it to the 'word list' wl. I get how to read from a text file but I don't know how to go about adding 'words' to a list, if that makes sense. So here's what I got:
string getWord(){
string word;
while (cin >> word){
getline(cin, word);
} return word;
[Code] .....
Source is an array that determines how many words are read from the text and length is the amount printed on screen. Here's the program I'm writing the implementation for:
#include <iostream>
#include <string>
#include <vector>
#include "ngrams.h"
[Code] ....
I'm supposed to use this as a reference.

I'm trying to read a string and then compare it to a word.
My code:
char* cmd = "start";
std::cin >> cmd;
if (strcmp (cmd, "eval"))
eval ();
When the program gets to the cin part, it breaks.

I want to copy the word entered by a user as soon as the user presses space(Just like the spell checker in word editors do). I'm using the following code:
private void ThisAddIn_Startup(object sender, System.EventArgs e) {
ConsoleKeyInfo info = Console.ReadKey();
if (info.KeyChar == ' ') {
Word.Range rng = this.Application.ActiveDocument.Words.Last;
[Code] .....
I'm getting the following error: An exception of type 'System.InvalidOperationException' occurred in mscorlib.dll but was not handled in user code. For the following line:
ConsoleKeyInfo info = Console.ReadKey();

Consider I have a vector of strings and then I use an istringstream to read each word of each element in the vector, why do I nescessarily use an istringstream?
This is the code that does what I just described (I think)..
Code:
for(auto &elem : svec) {
istringstream strm(elem);
while (strm >> word)
//Magic
}
What would be the equivalent of using something else than an istringstream in this scenario and how does the istringstream work?

Read in n, then n lastnames, and check to see if the first in the list is ever repeated again.Here's what I have so far:
Code:
#include <stdio.h>
#include <stdlib.h>
int strcmp(char *w1, char *w2);
int main() {
int j, n;
char string1[30], string2[30];
}
[code]....
I see the problem is that it lies within n amount of string that I am not going through every string to compare to the first one.How will do compare every string to the first one?
Current output:
3
alex
alex
alex
Not repeated
3
alex
ash
peter
Not repeated

correct the below code:
file already contains entries : 1st row username; 2nd row password.
check status required to write at third line and need to read or alter the check status value.
Currently this code is working if already there is a value for check status, then it is overwriting else UI hanging.
Code:
WriteCheckStatusToFile(BOOL& locVar) {
FILE *l_pFile = NULL;
CString l_strRememberCheck;
l_strRememberCheck = GetExePath() + _T("password");
CString sVar;
sVar.Format(_T("%d"),locVar);
