i need to display the current time and date in my program and use variable to store each of the time values like
a = 10
b = 29
c = 31
printf(``%d : %d : %d``, a,b,c);
which then give the output as - 10:29:31
How to save the time in variables in C....
i am using C in windows 7 and my complier is Bloodshed Dev C++
I'm trying to display the AM/PM on my program:
Also is there a way to display the time only instead of the date? How will i change the program to display the time in standard 12 hours, instead of 24 hours?
#include <iostream>
#include <time.h>
using namespace std;
int main()
{
time_t tim;
time(&tim);
cout << ctime(&tim);
}
I am doing a school project. The project basically is that it records the in and out time of an employee(of an particular company).The employee while checking in or out should enter a unique key generated specially for him so that no one else can check in and out for him.Then referring to the employees position( A worker or a manager or something like that) his total working time each day , for a week and a month is calculated. The company starts at 8 am and ends at 5 pm for 1st shift and for second shift from 3.30 pm to 2.30 am. Plus Saturday and Sunday off. Then after a month the program refers to the working time date stored in a file and calculates his pay(For workers its per hour salary and for managers it aint).
If an employee is consistently late the details are forwarded to the HR account( so that necessary steps are taken).This will support the company log the details of their employees duty time plus give enough detail to take action if someones always late. I'm doing this as a school project and it needn't be of enterprise class and all.. But i want the coding to perform as it should. Also i'm forced to use the old Turbo C++. Now i'm struck in the place where the time of the employees in and out time is logged. This coding does the work
Code:
void main( ) {
clrscr();
char dateStr [9],timeStr [9];
_strdate( dateStr);
cout<<" The current date is "<<dateStr<<'
[Code] ....
I think the second one is better as it not only gives me date but also gives me the day so i can check easily for the weekends. So, how these time functions work.
I am trying to use to save the current date and time into a char array using this code:
char current_time(char *date){
time_t result = time(NULL);
date = ctime(&result);
return *date;
}
main{
[Code]...
now when I output the date char array into a txt file I only get gibberish.
How can i assign current date as integer ?
for example:
today's date 26 Sep 2014 on a computer
i try to make as below
int day=26
int moth=9
int year=2014
I also research i think i will use time.h library surely
How to get system Date and Time and display it in the format DD/MM/YYYY ??
View 2 Replies View RelatedI have an assignment in which i must create a program which prompts for user input of current and birth date, which will compare said dates and output if its your birthday or not. I've completed a large portion of it, but cannot figure out how to get the user input of month as an integer such a 2 into February.
#include <iostream>
using namespace std;
class DayOfYear {

void input();

I am writing a C++ program which takes date & time input from the user. This is then parsed into a struct such as:
struct time
{
short year;
short month;
short day;
short hour;
short min;
};
My question is: how can I convert such a struct into a time_t object, which is an unsigned long giving the time as the number of seconds elapsed since the epoch Jan 1st 1970, 00:00, as set out in time.h.
I am wondering if this can be achieved using the standard library, or whether I just need to write a function to perform the appropriate arithmetic.
I'm having a problem with my homework. The task is to write a program that will take time and date typed by user, and increase it by 1 minute. I should write 3 functions - first calls second function that updates time and calls third function, if time is 00:00.Time update works, but date update does not.My whole written code:
Code:
#include<stdio.h>
struct DateAndTime {
struct date {
int day;
int month;
int year;
[code]....
I should check if inputs are numbers only, so I tried including isdigit function from ctype.h library, but that didn't work either, after I was trying it for a good hour or so, but I kinda rage quit that...
I have a text file in the form
5502 5202.3
1523 2536.1
1254 1256.2
17846 8956.2 and so on
left one is time and right one is pressure, I need to show the time value as it is but i need to use the pressure value to calculate air speed. I don't know how to use the strings to pick up the list properly. I did the calculation formula for the air speed but i can't pick the pressure value up from the text file. here's what i did:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;

i'm making a program that, given a person's birthdate or any other date, will display the day of the week of the person was born.
There is this part where it says "use a switch statement to make this calculation, If desired month is 12, add the number of days for November, if desired month is 11 add the number of days for october....
So it's suppose to start with "case 12 :...
I can't figure out what to write for the statement....
I need to add the current date to the end of a string but I only need to add the day and not the year or month.
Put the code This is what i have
char date[9];
_strdate(date);
cout << date << endl;
I want to store values permanently in a variable. The same variable should be able to be edited and saved by user, and whatever it is I need the value of the variable from the last time I modified it, like a database. database because i need this to set my connection string of the database.

My problem is that I am not getting the proper date and time. C++ keeps giving me some random date. I looked up c++ time format on the internet because this is extra credit and not in my book.

I have to write a program that stores information about students and displays results (Formated). Example-
Inputs ( # of students, First and Last name of student, the gender, age, and hieght. (height inputed as inches and outputed as feet and inches))
Student 2
---------
Jett, Joan Female
100 years old 5' 7"
Ive been falling behind a little due to working late and barely having time for my school work. Coming across several issues, one being an error with GENDER (Error C4700: uninitialized local variable 'gender' used:). As well as how to format the end result, i understand that u have to use #include <iomanip>, but am confused on how to format correctly.
How do you store a variable in memory so that it isn't changed when the program closes? I don't have any experience with this and am just wondering how it is possible. I am creating a program and want it to store your preferences and scores. In a simple program, everything is just reset and I don't want this for my program. How do I store a variable so that it stays the same, but can be changed even when the program is turned off?

The Object is to Store the low number every time time one is presented. so say I start the function the first number is the low number. but the trouble im having it once the function is called again it starts over(low number). Is there a way I can keep the function value once the function is called again? Any better way of doing this while keeping function in a class?

i have to write the current time to a file ?how to do it
View 2 Replies View RelatedIts a code in module of my program, where I need to print current time (HH:MM:SS) at regular intervals.

But when I am running this code I expect this to print difference in time due to delay. But it doesn't enter the delay loop, why ?

How to show only current date not time in webforms in visual studio as for date and time code is
Label1.Text = DateTime.Now.ToString();
What for only date not time
The first time my application opens up, it should get the local date out of the System and store this in a registry key. But the second time it should get the date stored in that registryKey and compare it to the date right now.And there is where I am stuck, I just don't know how to get the date out of that key and compare it to the date right now.
This is my code:
RegistryKey key1;
private void btnTrial_Click(object sender, EventArgs e) {
DateTime current = DateTime.Now;
key1 = Registry.CurrentUser.OpenSubKey("myKey");
if (key1 == null)
[code]....
at the last "if" statement it should compare the date stored in the key with the DateTime.Now.
I am having trouble compiling my interface. I am trying to store a reference variable as a member variable of the interface object. Compiler says that the variable has not be initiated correctly.
LCD inherits from VisualInterface which is expecting a DisplayDriver object to be passed in (DisplayDriver is another interface, but thats not important).
I pass the displayDriver object in when LCD is instantiated in maininterfaces.zip
I was pasing it before as a pointer but was told that this could cause me problems with memory leaks and a reference was better, but now I cant seem to get it to compile.
