C/C++ :: WebForms - Counter Won't Increment More Than Once Onclick
Jul 28, 2014
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!";

Parts of this program are missing. The last few lines are confusing, since the variable 'a' gets incremented then decremented. But there are no loops. I understand that the value of 'a' is passed to 'c' before 'a' is changed in both cases.
But where, and when, do the changes take place? Is the decrement ever processed? Is there a better way to write these lines?
Code:
main(){ int a = 21;int b = 10;int c ;
c = a++;
cout << "Line 6 - Value of c is :" << c << endl ;
c = a--;
cout << "Line 7 - Value of c is :" << c << endl ;
return 0;}

Is it possible to increment and decrement in the same loop? I can do it with 2 loops but id like to do it with just one loop.
Code:
for(i=1;i<=5;i++)
for(j=5;j>=1;i--)
Is there a way to do both operations with one loop?

I have two files NumDays.h and ClientProgram.cpp
clientprogram.cpp basically has the main module below
int main(){
// Initialized UDT object Declarations
NumDays hoursWorked_John; // Instantiate with Default Constructor
NumDays hoursWorked_Sue(36.9); // Instantiate with Initializing Constructor
NumDays hoursUsed_Sue(4.5); // Instantiate with Initializing Constructor

I can't figure out anything to put in for NumDays.cpp so it's not there.

In the following program.
void main() {
int a=1;
cout<<a++<<" "<<++a<<" "<<a++<<endl;
}
If I execute the above program i should get 1 3 3. But I'm getting different values when I executed this program. The values that I get after execution are 3 3 1.

I have created this code; it is a taxi management system. I've made a class 'List' which handle a linked list structure of the waiting taxis and waiting passengers. The class has a public int variable: waiting, which keeps track of the number of waiting taxis/passengers.
#include<iostream>
using namespace std;
class Queue{ //Class for indivdual taxis and passengers, which will be members of linked list.
public:
string id;
Queue *next;
Queue (){
[Code] .....
But when I run the code and type in a new taxi number, the code does not increment the number of taxis by one the linked list by one. I can't seem to find the problem.
BTW, in the 'int main', I've added "<< taxi_list.waiting" at the end of the line after the user inputs the new taxi registration number, so that I can see how many taxis are now on the list. This is what is being shown as zero, no matter what.

I created a table called registration and I have set an auto increment ID for each record. The problem is when I delete a certain record the ID didn't remove or deleted, for example if I entered these records: -
1,Bob,Bob123,Bob_2@hotmail.com then if I deleted it the next id record will be 2 which is supposed to be 1.
here is the SQL Command:-
CREATE TABLE Registration (
Reg_Id INT PRIMARY KEY IDENTITY,
Name varchar (255),
UserName varchar(255) NOT NULL,
Reg_Password varchar(255),
Email varchar(255),
Reg_Rank varchar(255)
);

I got the core dump file so I know exactly which line it crashes. Below are some of the information:
OS: Red Hat Enterprise 5.8
Example snippets of when the crash happen:
Code:
typedef map<int, MyClassObj> MyMapT;
.
.
void someFunction( MyMapT& inMap )
{
for ( MyMapT::iterator iter=inMap.begin(); iter!=inMap.end(); ++iter )
{
.
.
}
}
Using GDB, I am able to find out that it crashes at the "++iter" as the .h file indicate it was a "++" operation for the iterator. Tracing up the stack frame it indicate it crash during the copy constructor of some "__rb_tree_node". I did some Googling and it seems that is some Red-Black tree implementation for the map. Honestly I do not quite understand the Red-Black tree and I believe STL map is a very very well tested container, so the problem must lie in my code so that I can look out for it.

I have a class I am building called date and I've built all my functions to run and done all the necessary error checking in each function. However, my last and final function I have to write is where the # of days passed in as a parameter and then I have to increment the days by that many. And if the user does not increment any days at all in the parameter and leaves it blank, then it automatically increments by one day. I am having trouble with this. So for example if the user was to do this:
Date d1(10, 31, 1998); // Oct 31, 1998
Date d2(6, 29, 1950);// June 29, 1950
d1.Increment(); // d1 is now Nov 1, 1998
d2.Increment(5);// d2 is now July 4, 1950
The function starts out looking like this
void Date::Increment(int numDays = 1) {
}
I know I have to use a for loop to accomplish this. I just don't know how to get it to where the days passed in will go to the next month and then days passed in would go to the next year.

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;
