C :: How To Check Dates In Programming
Mar 6, 2015
I'm supposed to make a program that can tell which date, out of any number of dates entered by the user, is the earliest date. However, this is based off another program that I did not do in the last chapter. Since it's a pretty simple program to use as the base for the more "generalized" one, I decided to make the more basic one that can only take two dates, first. If it was just one integer, I could just use date1 for the first date and date2 for the second date, but each date uses 6-8 separate numbers.
how do I tell it something like, "if(date1 < date2)", with date1 and date2 including their month, day, and year. I could do a separate integer name/tag (I forgot what they're called) for each number, but that sounds like doing a lot more adding and subtracting, and like it could easily get messy.Should I, or can I, add all the numbers under the "date" together to see which date has the "lowest number" or "earliest date", or should I somehow handle each number, that is month, day, and year, separately?Here's the code so far:
Code:
include <stdio.h>int main(void)
{
int date1, date2;
printf("Enter first date (mm/dd/yy):
");
scanf("%d/%d/%d", &date1);
printf("Enter second date (mm/dd/yy):
}

In my WinForm, Our client insists to use Textbox instead of DateTimePicker field, and they want to input in ddmmyy format.
Using Visual Studio 2010 C# 4.0.
PC date time setting: GMT +08:00 dd-MMM-yy.
Assumed today date is 291014 (29-Oct-14).
CodeBehind:
DateTime inputDate;
// the WinForm allows user to input date not earlier than 2 years before today date and not more than 1 months from today date too.
//Assumed I input date as 261014 (26-Oct-14)
if(DateTime.TryParseExact(input, "ddMMyy", new System.Globalization.CultureInfo("en-US"), System.Globalization.DateTimeStyles.None, out inputDate)) {
DateTime minDate = DateTime.Now.AddMonths(-24);//Assumed it is 29-Nov-14
DateTime maxDate = DateTime.Now.AddMonths(1);//Assumed it is 29-Oct-12
I tried many methods but none works (I have checked many threads/forums also).
//Method 1
if(inputDate >= minDate && inputDate <= maxDate)
return true
//Method 2: B return true but A ***always*** return false, Why??
if (inputDate >= minDate)
A = true;

my a book or website where I can make a transition from console programming to GUI programming. I'm totally confused about this. I know how to program in console and can make a whole program based on console. I also know the OPP programming, but it's clear that nobody uses console programming anymore.

my problem is naming the function larger() with "int". At least that is what my compiler is leading me to believe.
Code:
#include <stdio.h>
struct Date{
int month;
int day;
int year;
};

Code for converting strings to Dates in C++.
Example: What is the date:
User response: 12/05/14
Any way I can code this to recognize it as a date, and make it so that the date is sortable? Not referring to the system date, but a user input date.

I have a simple table in SQLite:
Column 1: vistDate (stored as date)
Column 2: mileage
As a test, I created one row,
visitDate = 03/02/2013
Mileage = 10
I want to be able to add all the mileage between two dates but in my SQLite query, it returns zero mileage if the first date is not in the same month.
I am inputting the dates in the dd/mm/yyyy format above. It works fine for
Date 1: 01/02/2013
Date 2: 04/02/2013
i.e. 10 miles is returned as answer
but if Date1: 30/01/2013 I get Null.
Here's the query:
SQLiteExec("SELECT SUM(mileage) FROM mileageTable WHERE visitDate BETWEEN '01/02/2013' AND '04/02/2013')

I want that my DatePicker look like this:
The idea is for example if you a owner of Travel Agency and have website, when client want to go direct on your adrress in city that he or she can see on website that every weekend agency dont work(red color in calendar), other days they work(green) except of period 10.11-20.11 when they have vacation(numbers in calendar from 10.11-20.11 will be in yellow color).
I want to implement painting particular days in calendar by some logic.I suppose that I need to create my own class and inherit DatePicker from WPF, but what to override to get this if the inheritance DatePicker is the solution?

In this project a user needs to enter a numeric month and a year. The output is a single calendar month with the name of the month followed by a grid of the days. My issue is that my day alignment is off. for example: if you enter the month of December (12) and this year 2014 it says the month started on a Wednesady when in fact it started on a Monday. I am not sure if its my leap year calculaion or what.
#include<iostream>
using namespace std;
#define TRUE 1
#define FALSE 0
char *months[] = {
" ",

I'm trying to sort by age a vector of birthday dates. I'm using the functions in the <ctime> header to calculate the difference in seconds between two date but it doesn't work! If I try to print 2 different dates with asctime() or ctime() it either prints 2 time the same date or throws an exception! I post my code below: p.s.: I'm using a wrapper class called Date.
#include <ctime>
#include <iostream>
#include <conio.h>

i have been trying to compare a date format from SYSTEMTIME and a date from a text file(string).But its not working. I tried to change both to string(using osstringstream),char* and int(using sscanf) to do the comparison but with no luck. its pretty simple all i want to do is get the current system date and compare it with the date from the text file. Below is my code:
char szcurrentDate[MAX_PATH] = "";
char szdate_time[MAX_PATH];
SYSTEMTIME st;
GetLocalTime (&st);
GetDateFormat(LOCALE_USER_DEFAULT,NULL,&st,"yyyy-M-d ",szcurrentDate,MAX_PATH); //current system date
//std::ostringstream mm;
[code].....
note : i tried displaying just szcurrentDate and szdate_time they show the date exactly the same. in string,char* or int formats.

I want to compare dates of first week of every year input by user to determine that what was the day on 02/01/1998 compare to 02/01/2014, or 04/01/2001 compare to 04/01/2003.
I want to compare from 01/01/1997 , 07/01/2014.
For example user enter first date 04/01/2002 and other date 04/01/2003, then the program show that there was tuesday on 04/01/2002 and monday on 04/01/2003.

I have an assignment to write a program that will calculate the number of days between two dates (including leap years). We have to read the data from a file and in my current input file I have:
1 1 2000 1 5 2004
5 2 2005 2 5 2009
1 15 1998 1 15 2001
for testing purposes. When I run the program the console runs continuously spouting out "The days between your two dates are 1097." Which would be the correct output for the last set of dates entered, but I need to find out where I've messed up in my main.
#include <iostream>
#include <fstream>
using namespace std;
bool isLeap(int x) {
if (x % 400 == 0) {

sendto(): Invalid argument.I am new to socket programming.

I try to ON and OFF the LED's via parallel port. I connect the cathode of LED's with pin number 18 that is ground and anode of each LED is connected through a 1K resistor to pin 2 to 8. I write the following programe
Code:
#include <dos.h>
#include <stdio.h>
#include <conio.h>
#define PORTID 0x378
void main(){
outportb(PORTID,0x00);
getch()
}
But when i connect the LEDS to the parallel port all the LEDS are LIT while i also change the 0x00 to 0xff and so on. But no effect on the LED's.

I know this question must have been asked before, but the problem that I am facing is that I am using a library PoDoFo to parse PDF files. It seems that it is only compatible with C++.
Now I want the application to be web-based. That is, the user uploads a PDF file on the server, the server parses it and the parsed content is then sent back to the user.
Is such a thing possible with C++, or maybe any good work-arounds? Or should I look at server-side scripting languages like PHP and their respective libraries?

I have attached a circuit diagram below, which has been tested. Currently you have to manually push the switch to change the brightness of the bulbs. I want to program a chip to automate this.
Over 90 days the chip will output a high signal in replace of the switch every set period of time (say once every 1.5days). I can use any chip but the smaller the better!

why an array would lose its contents when I believe it shouldn't. Below is a skeleton program just to kind of show what seems to be happening. Basically I set up the delims array with just a star. The program runs a good number of times but at some point the delims array gets lost. My guess is the stack is overflowing or something? But it "appears" all other variables are ok (although I cant be sure).
I move the char delims into the while loop. What is this "actually" doing to the original delims variable ... are we wasting memory here (bearing in mind the original delims variable is sometimes loosing the string :/)
Code:
somefunction()
{
char delims[] = "*" ;
char *result = NULL ;
while (1)
}
