I am looking for a function or any example that shows elapsed time in seconds and minutes. I didn't find any solution for both OS Win and Linux. I am looking for example that works for both - win and linux.
View 14 RepliesDesign, implement, and test a class that represents an amount of time in minutes and seconds. The class should provide a constructor that sets the time to a specified number of minutes and seconds. The default constructor should create an object for a time of zero minutes and zero seconds. The class should provide observers that return the minutes and the seconds separately, and an observer that returns the total time in seconds (minutes x 60 + seconds). Boolean comparison observers should be provided that test whether two times are equal, one time is greater than the other, or one time is less than the other. (You may use RelationType and function ComparedTo if you choose). A function should be provided that adds one time to another, and another function that subtracts one time from another. The class should not allow negative times (subtraction of more time than is currently stored should result in a time of 0:00). This class should be immutable.

I want to convert seconds into hours, min and seconds. I was able to test it with a small equation turning seconds into hours but now it returns zeros for every entry.
Code:
#include <stdio.h>
void secCount(int *seconds, int *hours, int *min, int *sec);
int main(int argc, const char * argv[]) {
int sec=0, hours=0, min=0, seconds =0;
[Code] .....
Program should continually have user enter a positive integer, and quits on zero entered. This entered number represents the total number of seconds and after each number is entered a function is called that displays the time in hours, minutes and seconds. Sample output is as follows:
Enter Total Seconds --> 3605 1:00:05
The function needs only one value parameter and should return nothing back to main. If the minutes or seconds are a one digit number then make sure to display a leading zero as the example above shows.
Here is my program. my question is how do i make the numbers appear like this? 1:00:05

I have a question. I would like to actually have some measure of roughly how long it takes to do a fwrite to a drive. When I do the following:
clock_t begin = clock();
unsigned long long size_t = fwrite(send, 1, transfer_size*sizeof(unsigned long long), wpFile);
clock_t end = clock();
double long elapsed_secs = double long(end - begin) / CLOCKS_PER_SEC;
Unfortunately, I don't get any different result for different transfer size!!!
My guess is that the clock_t , once it issues a fwrite command, some how stops its measurement, and it comes back again, when I am already done with fwrite. I do get the almost same measure, whether my transfer size is 32KB Byte or 16MB ! Which I was indeed expecting to see a huge difference. I wouldn't really want the exact real timing measure (well off course it will be nice to know); and all I care about is to see some difference in time whether I am doing KB transfer vs MB transfer.
Some rough measurement required of the actual time being elapsed for fwrite function?

In my class I'm trying to display the elapsed time as my label on a windows form. I've been reading up on all the different articles online and have tried these three methods all with the same result:
1. Using the System.Timers class
2. Built in Timer sub-class
3. Defining directly inside of my class the StartTime, etc. variables.
All of these still result in the following error:
Cross-thread operation not valid: Control 'User_Interface' accessed from a thread other than the thread it was created on.
Currently, my windows form is being called by another class, but I'm not sure if this is the cause of the problem.
This is a sample of the code that I'm currently using to show the elapsed time:
private void OnTimedEvent (object source, ElapsedEventArgs c)
{
TimeSpan time;
currentTime = DateTime.Now;

I have a code to check the last time modification of a file using "gmtime". Is it possible to remove the seconds in the result?
Here is my code:
struct tm* clock;// create a time structure
struct stat attrib;// create a file attribute structure
stat("test.txt", &attrib);// get the attributes of afile.txt
clock = gmtime(&(attrib.st_mtime));// Get the last modified time and put it into the time structure
I need to get the current time, have the system sleep for a period of time, then return the difference in seconds.
#include <iostream>
#include <string>
#include <ctime>
#include <time.h>
#define _CRT_SECURE_NO_WARNINGS
using namespace::std;
// in the <ctime> library is a function time(0)

I'm not receiving an errors but the return value is not correct. It's returning 1.4259 no matter how long it sleeps for.
i create a structure called time. Its three members, all type int called hours, minutes, and seconds. This is in 12:59:59 format and i finally want to print out the total number of seconds represented by this time value.
long totalsecs = t1.hours*3600 + t1.minutes*60 + t1.seconds
i am using this formula but facing errors?
I have to write a program for class in which users will be inputting:
start time = startTime
number of minutes = callDuration
so first off, teacher wants us to input time as a floating point number such as 09.00
How do I validate the time so that users cant input i.e. 09.61 for every hour? In other words, so the user cant input minutes 60-99 for every hour.
then, when calculating:
endTime = startTime + callDuration
how would I make endTime display a correct time in such a situation: endTime = 09.45 + 00.30
so that it displays 10.15 not 09.75
I have a function which sometime takes more than 24 hours to run. So I want a code which will check the time and exit the function if the function executin is not successful and return to main function.

I am reading up on the clock() function: URL....It states: "On a 32bit system where CLOCKS_PER_SEC equals 1000000 this function will return the same value approximately every 72 minutes."
How could this return the same value, if clock is the number of clock ticks elapsed since program execution. Wouldn't the number of clock ticks continue to grow, and as such, when we divide by 1000000, the return value should continue to grow. So how does this function return same value every 72 minutes?
I am currently working on a lab for my intro to programming class and the lab is asking for a long distance call calculator. Based on the times that you start your rate will change. If the call starts from 00:00 to 07:59, Rate = $0.07. If the call starts from 08:00 to 18.59, Rate = $0.12. Lastly if the call starts from 19:00 to 23:59, your rate is $0.28.
Then on the output you must show the start time, end time, rate, and total cost of the call.
My confusion is on the end part of the code (the output).
I know you have to use the % operator to convert minutes to hours, but I don't completely understand it which is why I am here. How does the modulus do that? And how will it go over to the next hour if the call starts at 1:35 and ends after 30 minutes (2:05)?
Here is what I have so far.
#include <iostream>
#include <string>
using namespace std;
int main() {
float callStart, minutes;
double cost;
char choice('Y');
string rate;

how to add seconds to CTime in VC++?
Ex :
int i=0;
i=250;
CTime tm;
tm=tm+i;
I am trying to transform seconds into HH:MM:SS. I thought it would be easy using the TimeSpan functions however my hours exceed 24 hours now and then therefor it is not viable for use.
private string getFormattedTimeFromSecond(double second)
{
TimeSpan t = TimeSpan.FromSeconds( second );
string answer = string.Format("{0:D2}h:{1:D2}m:{2:D2}s",
t.Hours,
t.Minutes,
t.Seconds);
}
This is what I have tried, however it does not like it much when hours exceed 24.

Its a 32bit console application, I want the countdown timer outputted above each question on the right side, timer only needs to output the time left at the top of each question so a live outputted timer is not important.
Questions are not random generated.
Also how to output "out of time" if the timer reaches 0 and for the test to end, I think branching is involved not too sure.
I already have, std::srand( std::time(0) ) ; at the start of the test to randomly generate the answer order.
I am trying to write a program that will display a table with "seconds" and "Distance". Where Seconds goes from 1-12 and the distance is displayed according to each second.

I know there has to be a system call to pause (not system("pause") execution of a program for a few seconds. I would like to give the illusion that my program is 'thinking' rather than just spit out the result as soon as the user has hit the enter key.

I wrote one application using STL API's [vector,map,make_pair,pair]. Application is working fine in Windows 2008 server.
Same application failed in Windows Server 2012 R2 and the failure is randomly occurred.[once in 10 iteration]
I suspect some of my PC update is the root cause for this random failure.
I would like to know which is latest STL version for Windows 2012 R2 server. Is there any latest patch/update released by Microsoft?
Does it good idea to use Boost lib for the same? Which is the Boost lib version for Windows Server 2012 R2.
There is no compilation issue on Server 2008/Server 2012 R2 server.
