C++ :: Error With Running Counter Through Loops
Jan 27, 2014
I'm working on a program that reads data in line by line from an input file and the sorts it into two arrays, one string, one float. They are parallel arrays managed by a running data count of how many lines are read in, however, I'm getting an error with my data count. My test file only has 8 lines but when I cout my data count, it's like 35,485 or something like that. Here's the code I have so far (my program still has other components to write but I haven't gotten that far.)
Code:
#include<iostream>
#include<iomanip>
#include<fstream>
#include<string>
#include<sstream>
using namespace std;
//global constants
const int MAX = 1000;// maximum numbers of input for array size

How do I add a counter for the comparisons so that it increments every time the two array value are compared?
// Session5.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <iostream>
using namespace std;
const int NMAX =10;

I am not sure why this is happening but I am simply trying to make rounds with my code and have it stop when one of two things, or both, happen.
#include <iostream>
#include "Classes.h"
#include "RNG.h"
#include "select.h"
#include "Fitnesschk.h"
using namespace std;
/*Global Variables************************************/
const int column = 32;
[Code] ....
I've tried resetting and renaming all variables but I don't see any conflict. I tried declaring in different areas but no dice. The other issue I have is that fittest always returns 0 even if the function returns 1. So it infinitely loops. When I go through looking at the variables. the fittest variable never changes even if the function returns 1 and round seems to reset after reproduce is called.
Here is the supporting code.
For Fittracker:
int fittracker(person man[], int row, int column){
for (int y = 0; y < row; y++){
int fit = 0;
for (int z = 0; z < column; z++){
if (man[y].data[z] == 1){

One that fills different char arrays the idea is to use a single char to represent a char such as 255 but if more than it then use a char array of two chars to represent the next char 00 because if only one is needed it would take less disk space than 0,255 as it would in an array.
My goal is to do this all the way up to an array that can hold 255,255,255,255 but only use the more complex array if needed Example: a char of 255 takes much less space than a char array of 4 chars so that instead of 0,0,0,255 it is written to disk as a single char whereas a char array of 200,0,0,1 would be written as a 4 byte char array. use single char to represent values from 0 to 255 use two char array to represent 0,1 to 255,255 three for 0,0,1 to 255,255,255 and four for 0,0,0,1 to 255,255,255,255

I am trying to make a program which reads a text file, separates the strings into words, then finally saving and counting each different word.
When I comment out the code where it is supposed to search for the same word in the table, the program doesn't work.Am I doing something wrong with strcmp or the loop? The 'break' just exits out of that 'for' loop right?
Code:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#define WORD_MAX 500
#define LIST_MAX 500
int main(){
int i, j, find;

I'm trying to write a small brute force application in C on Ubuntu 14.04.1 using Code::Blocks with gcc-4.8.2. It's nothing special and just for practice.The focus is on a parallel procedure that generates strings by use of OpenMP. Every time a string is generated, the counter variable should be incremented. At the end, regardless of whether the search string was matched or not, it outputs the correct number of all generated strings (counts).It works fine so far.Here is my source code example:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <omp.h>
/* Global variables */
const char Literals[] = "abcdefghijklmnopqrstuvwxyz";
const int NLiterals = sizeof( Literals ) - 1; // NLiterals = 26 Bytes.
const char SearchString[] = "test"; // I.e. until 'test' there are 355414 counts.
char MatchString[16];
}
[code]...
This should speed up the process of generating strings. But if I do so, always when the program has a match the number of counted strings is wrong. Here are some possible "wrong" outputs: Code: Match: 'test'! 40710 tries. <-- number of tries (counts) is wrong! or Code: Match: 'test'! 40375 tries. <-- number of tries (counts) is wrong! But if the program doesn't have a match (i.e. when I change SearchString to something like the following line), then the number of counts is correct: Code: const char SearchString[] = "test0"; The only thing I have to do before, is to change the follow line from:
Code:
printf( "
No match! %u tries.
", Count / 8 ); to Code: printf( "
No match! %u tries.
", Count );
But also it can happen that there is no output. Like an infinite or endless loop. How can I improve the source code in order that the correct number of counts is always displayed and what can be the reason for the endless loops time after time? Both issues appears only by the use of Code: #pragma omp for schedule( dynamic ).

The program should be print the numbers 0 through 10, along with their values doubled and tripled. The data file contains the necessary variable declarations and output statements.
Example the output:
Single Double Triple
1 2 3
2 4 6
3 6 9
4 8 12
here my code tell me if correct
#include <iostream>
#include <cstdlib>
using namespace std;
int main () {
int x, double, triple;

I have to write a program that asks the user to input a positive integer, counts how many primes there are before this integer, then divide the number of primes by the integer. Here's what I have so far:
int n;
int counter = 0;
cout<<"Enter a positive integer n.";
cin>>n;
[Code]....
the value of the integer counter is supposed to increase whenever a prime number is identified but it's increasing n times

How can i form a counter of say 30 elements so that to meet following requirement,
I need to access 5 elements out of 30 elements and out of these 5 elements once the one value is printed (i.e now access for remaining 4 element will be left) other one should get added immediately to this 5 element set, from remaining total 25 elements. In this way 5 element count will be there always.
I am trying this as follows, by forming vector of 30 elements accessing its 5 elements as :
for (iter = vector1.begin(); it < vector1.end();it++) {
for(int count = 5; count >= 1 ; count--) {
cout << "Print value<" <<count<<"> : "<< *it <<endl;
it++;
}
}
This displays 5 elements at a time but counter "count" waits for to finish off its remaining 4 elements however i want to maintain this counter to 5 elements always.

I am trying to modify a PerformanceCounter I have created in C#. But it doesn't seem to be that it is being changed. This counter needs actualy to be a flag : 0 or 1.
I took the following code from the web. It created the collectors category along with the counters well. But the RawValue always shows 0!
I am working on Win7/64.
using System;
using System.Diagnostics;
using System.Runtime.InteropServices;

After searching, it seems that I've finally arrived at the good old traditional "Random Number Game". I've been presented with solving this problem in the context of Visual C#.
I've solved the first part of the problem: Have the user enter a random number, display "Too high" or "Too Low" depending on the entry. If user guesses, let the user know. That part of the problem I was able to solve with only 3 IF statements. In it's current version, instead of using all IF statements, I saw where 3 test conditional weren't needed. (If it's not greater nor lesser it's equal or,.... "otherwise do this").
An enhancement to the problem ask that the user be notified of how many guesses it took to get the number correct. I reasoned that number of guesses could be translated to mean " number of iterations ".
I'm having trouble using the counter variable to track the iterations, then display the total iterations. I'm not seeing how to increment that value with each loop. I've basically reached two results no matter how I've used counter and written the while loop. The first one returns back to me "the guessed number". Example, if I guessed 10 times and the lucky number was 58, the display statement in the ELSE clause became: "Congrats. You guessed the number in 58 tries!".
The other result is what's returned by the code in it's current form. I think it'll be clearer for me to debug from this point then the previous. Here, I can see how I reach "Congrats. You guessed the number in 2 tries!". It's apparent that counter is being incremented by one regardless how many guesses the user makes. On the contrary, it's not so apparent to me how previously, the value returned by the counter variable at the end of the loop was actually the value for the random number generated and the user's entry (hence, the correct number) and NOT the total loop iterations.
Here's the code :
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

I have a method that changes a canvas color after set intervals, e.g. start timer, 5 seconds green, 3 seconds red, then stop. This functionality is provided in the interval method. The problem I'm trying to achieve is getting this sequence to repeat for a set number of iterations.
I tried to solve this by setting up a counter after the timer is stopped but the code keeps repeating indefinitely by starting and stopping over and over instead of the max of 6 iterations I had set. In debugging the problem, I watched the value of 'i' and when the 'if' statement is set to false. The 'if' statement gets set to false after 7 iteration as expected but the start(); keeps getting called.
void myTimer_Tick(object sender, EventArgs e) {
//Assign text box string value to a time span variable.
TimeSpan workTm = TimeSpan.ParseExact(wrkString, @"hh : mm : ss : fff", CultureInfo.InvariantCulture);
TimeSpan restTm = TimeSpan.ParseExact(rstString, @"hh : mm : ss : fff", CultureInfo.InvariantCulture);
// update the textblock on the display
// with hh, mm, ss, ms
ms = myStopwatch.ElapsedMilliseconds;

I have a counter that onclick should increment 1 and it does that on click, but if I click the button again, it won't increment again. Instead it will be stuck at 1. How can I make it go up if the button is clicked more than once? Also this is a web application.
protected void submitAnswerButton_Click(object sender, EventArgs e) {
int counter = 0;
if (mathAnswerTextBox.Text == answer.ToString()) {
answerStatus.Text = "Correct!";

I'm trying to create a program that rolls a dice a few thousand times and print out how many times it lands on each face and then print out a graph using x's as a visual representation using classes.
output looks like this:
1 --- 2000 xxxxxxxxxxxxxxxxxxxxxxxxx
2 --- 1950xxxxxxxxxxxxxxxxxxxxxxxx
.
.
6 --- 2050 xxxxxxxxxxxxxxxxxxxxxxxxxxx
I need a method called int count(int face) inside my class that returns the number of times a particular face has appeared, I just don't know how to incorporate this. I think I should use a constructor and destructor but i'm new with those and knowing when to actually use them.
Here is what I have so far that shows how it should look when printed, just struggling to convert using a class.
#include <iostream>
#include <vector>
#include <cstdlib>
#include <ctime>
using namespace std;

The best I could come up with is this.
while(true){
wisdomCnt++;
_stprintf_s(szBuffer, _T("%i"), wisdomCnt/10000);
TextOut(hdc,120,10,szBuffer, _tcslen(space));
}
but the program is constantly loading and clicking anywhere causes it to stop responding. Is there a better way to do this especially in Win32 API?

So I have an insertion sort function implemented that sorts through an array, but I'm having a problem showing the correct number of comparisons to work.
Each time I'm checking a value with another, the counter should update.
For instance, having an array of 10 elements going from 10-1 should give 45 comparisons, but I'm getting 54 comparisons.
void insertionSort(int a[], int& comparisons, const int& numOfElements) {
int j, value;
for (int i = 1; i < numOfElements; i++) {
value = a[i];
for (j = i - 1; j >= 0 && a[j] > value; j--)

I am writing a program that minicks the library reserve system at my university and the problem is that when i run the code and reserve a room i am to keep track of the amount of times the room has been visited. To do this i set up a array roomcount and I count up by one every time i assign a room, The bug lies with when you reserve a room, then run option three, it will show that the previous visits is at 1, which is good. but then if i leave the room(option 2) and then run option 3 again to view the status of the rooms, the previous visits is set back to 0, which is not good. Ive been staring at this for hours and asked numerous people by we can't seem to figure out why the roomcount variable resets.
#include <stdio.h>
#include <math.h>
int main (void) {
int choice;
int roomchoice;
int i = 0;

The question is: Define the class Counter. An instance of this class is used to count things, but the counter should never be less than 0 (non negative number). The member variable should be private. I realize what I'm suppose to be using but can't implement the member functions needed..
int main(){
int value;
cin >> value;
Counter myCounter(value);
for (int i = 1; i <= MAXLOOP; i++) {
myCounter.increment();

I am trying to make a basic app that will loop through an unordered list with repeats and count how many times a specific item repeats. Example would be I select a state from the list box and it will tell me how many times it is listed.
This is the code I have up so far, trying to keep it basic. I am missing something, something related to the counter? I think I have some of the better half up but I am not sure...
Code:
Private Sub ListBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles lstBox.SelectedIndexChanged
Dim wins As String = lstBox.SelectedIndex
Dim foundwins As Boolean = False
Dim i As Integer = -1

I am currently working on an assignment.
#include <iostream>
using namespace std;
int main(int argc, char *argv[]) {
char letter;
int count = 0;
double ppl = 0;
double finalCost = ppl * (count - 1);
[Code] ....
I am trying to create a word counter program that asks for the price per letter and then asks for the sentence they are writing. The app should then calculate the number of letters and give the total cost similar to:
You have 40 letters at $3.45 per letter, and your total is $138.00.
Everything compiles fine but when I run it the inputs don't work and it outputs:
You have -1 per letter, and your total cost is $-0.
