How to reset/clear dictionary?
I've already tried:
someList.Clear()
and
var keysToRemove = new List<string>();
foreach (var e in someList)
{
keysToRemove.Add(e.Key);
}
foreach (var key in keysToRemove)
{
someList.Remove(key);
}
And keep getting the error: An item with the same key has already been added. I'm using VS 2012.
int counter won't reset to 0 when I click the start over button.
protected void startOverButton_Click(object sender, EventArgs e)
{

Im trying to make a reaction game. I have a grafic that comes up, and the timer starts and when i hit the grafic the timer stops. But my problem is that the Timer doesn't reset.
View 2 Replies View RelatedIn the traditional for loop, you could make the loop start again by resetting the int value
for (int i = 0; i < 10: ++i){
//Do something
i =0;
}
Then it would start the loop again. However I can not seem to find a way to do this with the range based for loop. Is there anyway to force a range based for loop to start from, i = 0 ?
for(const auto &i : vec){
//Do something
//Restart for loop
}
I need the number of moves to reset to zero every time because right now when when i enter the next number of disks the moves from before are added to the new set of moves. Here is my output
how many disk are you going to start with? 2
It will take 3 moves
how many disk are you going to start with? 2
It will take 6 moves
how many disk are you going to start with? 2
It will take 9 moves
how many disk are you going to start with? 2
It will take 12 moves
how many disk are you going to start with?
the number of moves for 2 disks should be 3 but as u can see every time i enter 2 disks it just adds to the last number of moves how can i fix this ?
//Purpose: Recursively solve the tower of hanoi problem, moving n disks from A to C.
#include<iostream>
#include<conio.h>
using namespace std;
double number;
void move(int,char,char,char);

I've been taking a C++ class, and for a project we need to do, we have to create a simple quiz show game while putting the high scores and names inside a .txt file. We have lessons we can look at to complete it while learning. But at the end there's always a challenge that we should complete to show that we've actually learned the information. For the challenge, we needed to take the information in the .txt file and reset it to its original information. So say there's 5 people preset that have high scores, then a person plays the game and the program asks if they'd like to reset the list. If the user inputted 'y' or any key that needed to be pressed, the program would reset the .txt to its original information.
This is the code that creates the program.
// Include Libraries
#include <iostream>
#include <string>
#include <fstream>
// Include standard namespace
using namespace std;
// Declare Global Variables

It works how I need it to and there aren't any problems, necessarily, but I want to know if there's any, more efficient, ways of completing this task. Like if there's any already made function of resetting a file.
This is the code that resets the file. As you can see, it just uses the information earlier in the code inside the if statement. Is there any pre-made function or method of resetting a file?
cout << "Would you like to reset the high scores list? (y or n): ";
cin >> ask;
if (ask == 'y')
{
High_Score[0] = 25000;
High_Score[1] = 12000;
High_Score[2] = 7500;
High_Score[3] = 4000;
High_Score[4] = 2000;

Anyway, I am working on a project and have compiled a dictionary text file of english language words. I want to use this dictionary for an autocomplete feature that I would like to add to the program.
I am having trouble finding anything about either
1) an autocomplete library I can #include into my code.
2) how to write my own.
I need it to be in either C or c#. If i can get the algorithm in C then I can just convert it to c#
how to see if what the user says is in the dictionary. I do not know what to put in ContainsKey() or after the information in console.writeline. I just want the user to type in the key then see if it is in the dictionary then print out the value if it is.
while ( Console.ReadLine() != "exit" )
{
Console.WriteLine("Type in word");
if (clothingDictionary.ContainsKey()== true)
{
Console.WriteLine("key is {0}, value is {1}", );
I am creating a student management system (using classes) for my assignment and am stuck with designing UI. I made the classes but am not sure what the best control is to display items from a Dictionary<> object. Right now I am using the ListView because of the columns in details view...just want to know if there is a better, simpler control I could use if i want to display data (without using sql)...or is the good old "next" and "previous" option the simplest?
View 9 Replies View RelatedI need to create code based upon the following pseudo code:
dictionary=vector
file containing words to search for=external file
While there more words to search, for search the dictionary if the entire dictionary is searched and the word is not found, return the word, search the dictionary for the next element (and so on)
I cannot for the life of me figure out the sequence of loops to do this. The following code returns all of the words instead of just the ones not found in the dictionary, but it's all I've got after countless changes:
#include <iostream>
#include <fstream>
#include <vector>
#include <string>
using namespace std;
int main() {
string dictword;
ifstream dictionary;
[Code] ....
And it returns every word in the external file.
A friend of mine is taking classes currently and using open office. He asked if I could create a program that would spell check medical terminology. He said that he has a program that works with Microsoft word but it will not work with open office.

I first created a class called TheoryQuestions and created a new instance of the class for each dictionary entry. Each entry contains strings for Question, RadioButton Text(x4), and Correct Answer.
The random generator is actually selecting a random number as I can display the generated number in a label. The problem is that the dictionary string values held in the dictionary position represented by the random number are not being displayed.
Here is my TheoryQuestion Class
public class TheoryQuestion {
bool BeenAsked = false;
public string Question

I need to assign unique integer values to words in a dictionary that have the same alphabets, for example 'act' and 'cat' should have the same integer value. Would just adding the ascii values of the letters be sufficient?
View 1 Replies View RelatedI have a script that checks and compares two lists from an offline dictionary. Dictionary.txt which has a lot of words in it. input.txt will compare to dictionary.txt and print out anything that matches in CMD.
However, instead of using an offline dictionary is there anyway to make a code check an online dictionary? If so, would this process be slow or fast?
finishing my program which needs to do the following:
(i) Write code to read in the dictionary into an array of words
(ii) Write code to check the spelling of a word entered by the use
(iii) Like Scrabble / Countdown the user enters the letters they have and my code must find the word using the highest number of those letters
I have completed a good bit so far but I'm stuck on my checkSpelling() and findWord() functions as well as part (iii)

So I'm rewriting an old project of mine, and I'm trying to determine if there's truly any better way to map the data taken from a text file "dictionary" into the correct class fields for further processing. For example:
FNAME=MY_FIRST_NAME
ADDR=123 SOMEWHERE LN, NOWHERESVILLE, TX 01234
LNAME=MY_LAST_NAME
TOTCALLS=47
In each of these, I'd need the "value" (MY_FIRST_NAME, MY_LAST_NAME, etc) from the "keys" (FNAME, LNAME, etc) to be mapped to the proper class fields. Say, for example, I had this:
Class DataProcessing {
public string Address;
public string FirstName;
public string LastName;
public int TotalCalls;
...
}
I would need DataProcessing.Address to be set to the value in the ADDR key/value pair. The same would be true for each other field. The problem is that based on the text file's source (which isn't under my control, and won't be changed anytime soon), the key/value pairs are not always in the same place...so a second file could have the data as such:
TOTCALLS=47
ADDR=123 SOMEWHERE LN, NOWHERESVILLE, TX 01234
LNAME=DARKPOETCC'S LAST NAME
FNAME=DARKPOETCC'S FIRST NAME
Any smarter way to do this than looping through each line that was read in from the file, and determining where it belongs, such as (pseudo code follows):
IF FieldName == "TOTCALLS" THEN
//Assign to TotalCalls field
ELSEIF FieldName == "ADDR" THEN
//Assign to Address field
ELSEIF FieldName == (You get the picture...)
//Do thing N_Field
Over the last few days, I've been trying to implement a spell checker in c++ that checks if the inputted word is in the dictionary file on my computer. However, as I'm nearing completion of the project, I keep running into more and more errors, some of which I do not understand. My program is complete, albeit, with some minor bad practices (I hard coded a few things just to get the program up and running.For some reason, everything works well until I output spelling suggestions. I type in "mses" (attempting to spell mess) and it returns some strange characters. It does definitely recognize that there are two permutations that match words in the dictionary (however they are both mess due to the algorithm implemented), and I don't understand why? I will work on removing the duplicates after.
// Spell Checker.cpp : Defines the entry point for the console application.//
#include "stdafx.h"
#include <stdio.h>
#include <string>

Write a function that sorts a dictionary list alphabetically. Here's my code:
Code:
#include <stdio.h>
#include <stdbool.h>
struct entry
{
char word[15];
char definition[50];
[Code] ....
It's compiling ok, and displays the first call to the printf function from main. However, after this I get the 'Segmentation fault (core dumped)' at the terminal, presumably from the call to the dictionarySort function.
I had a little look around and found it is something to do with non-existent or not available memory addressing, I think? Even so, I can't figure out what is causing the issue in my code.
