C++ :: How To Get Uniform Increment Of Milliseconds - System Time

Jul 31, 2013

I am a bit lost as I am new to C++ and programming in general.

#include <stdlib.h>
#include <stdio.h>
#include <fstream>
#include <iostream>
#include <windows.h>
using namespace std;
int main() {
ofstream myfile;

[Code] ....

msi
1247
1248
1249
1250
1251
285216ms delay
2853
2854
2855
2856

in the csv file, as above, after every 12 to 13 increment of i there is a skip of 15ms to 16ms. I do not understand why the ms is not a uniform increment. Is there another way I can get a uniform increment of ms?

C/C++ :: System Time And Enumerators

Mar 22, 2015

I need to take the system time and turn it into this format: 03:20 PM, Tuesday March 17, 2015. I am suppose to use 3 enumerators for the day of the week, the month, and AM or PM. I am having a lot of trouble with converting the system time to year, month, day, hour and minute. I also know there are a lot of functions that would make this more than simple, but I have to do the calculations and use enumerators. Here is what I have so far:

#include "stdafx.h"
#include <ctime>
#include <iostream>
#include <time.h>
using namespace std;
enum Days{SUN, MON, TUES, WEDS, THURS, FRI, SAT };
enum Months{JAN,FEB,MAR,APR,MAY,JUNE,JULY,AUG,SEPT,OCT,NOV,DEC};
enum Time{AM,PM};

[Code] ....

C++ :: How To Linearize A Complex Non-uniform Tree

Oct 25, 2013

I have a tree structure that works likes this.

Each node (if its a 'normal' node) can have 2, 3 or 4 children. I know how to linearize a normal quadtree though it is not memory efficient in this case as the linearization only works for full trees. I'm okay with holes though.

But my tree is slightly odd in that it has non-normal nodes. For example, two leaves will point to a 'dead' node and that dead node has 3 children. Sometimes, 3 leaves will point to a dead node and that dead node will have 2 children. Sometimes, 4 leaves will point to a dead node and that dead node will have 4 children.

So normally, a node will only have one parent and multiple children or it'll just be a leaf. But there are dead nodes that can have 2, 3, or 4 parents and will subsequently have 3, 2 or 4 children respectively.

This is for point location within a Delaunay triangulation and operates off of the idea of volume spanning.

What I abstracted in my code is a 2-to-3, 3-to-2 and 4-to-4 flip. The idea is ,we take 2 tetrahedra and replace them with 3 good tetrahedra but they span the same volume which is good for point location.

As of now, the code that I have works fine. It triangulates tetrahedra and repairs them accordingly but for certain inserts, the search algorithm takes incredibly long and I'm trying to fix that.

I figured a linear structure would be a good attempt so how to linearize a tree that behaves almost polymorphically.

C++ :: Creating Timer - Count By Milliseconds And Return A True Value

Jun 19, 2013

I'm looking to create some sort of a timer. I'd like it to count by milliseconds and return a true value when it counts to a specific time. It would be used something like this:

if(alarm(1000)) {
// do some code
}

I tried using time.h, but it doesn't seem to have any millisecond commands. I need something faster than a second.

C++ :: Increment And Decrement - No Loops

Sep 29, 2014

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;}

C++ :: Increment And Decrement In The Same Loop?

Sep 25, 2014

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

C++ :: Increment In Variable Not Taking Place

Oct 27, 2013

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.

int counter = 0;

C Sharp :: How To Decrement Auto Increment ID

Nov 5, 2012

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)
);

C++ :: What Could Cause A Core Dump At Iterator Pre-increment

Oct 15, 2014

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.

C++ :: Increment Member Function In Date Class

Feb 10, 2015

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.
