Got it. Is there a way to apply this to tracking the system clock instead of the elapsed time of a program?
Have a great day, Alex

If you look in time.h you will find that time_t when using dev
c++ is just a
long int. And what it is, is the amount of seconds since 1970
some time.
If you read this page you will learn more.

Why I use null is because that gives you the current time. I
used the
modulus because that gives you the remainder in a division in
this case it
would be 5 seconds. If you had 70 seconds it would return a
remainder of 10
instead of 5.

Thanks. A couple questions:1. Exactly what is the time_t object and what can you do with
it?
2. Why, to get seconds, do you mod by 60 yet minutes you divide
by 60?
3. Why do you pass null to the time function, and what does that
time
function return?
Have a great day, Alex

Ok while I was waiting on your response I wrote this to check theminutesand seconds elapsed while running some commands. Note I did notuse anyspecial libraries like a Date class that they have in mostcompilers. Hereis the most basic with out using assembler snicker. It works forboth gccand visual studio's c++ Just delete the defined lines dependingon whatyour using.
#ifdef VC++_COMPILER #include <windows.h #endif #include <time.h #include <iostream
using namespace std;
int main(int argc, char* argv[]) { time_t t1 = time(NULL);
//do some tasks here for (long i=0;i<65;i++) #ifdef GCC //_sleep(1000); #endif #ifdef VC++_COMPILER Sleep(1000); #endif
time_t t2 = time(NULL); int seconds=(t2-t1)%60; int minutes=(t2-t1)/60;
cout <<"elapsed time = "<<minutes<< " minutes "<< seconds<< "seconds"<<endl;
return (0);
}

Oh sorry the original mail did not come to me it got junked I gottheresponse and that was the one I was replying to.
Now I can tell you how to get system time all the way to theassembler levelbut it helps in knowing what c++ environment your working inbecause itmakes a difference for example they have data and time classes inMicrosoftthat is some times easier to use then to actually write the codeyourself.So tell me what compiler your using and for what operating systemand I willgive you an example.

The example did not have stdlib, and stdio was just the word, noh. Thanks.The question still stands, though: how can I get the minutes ofthe systemtime? Apparently there is a time_t object, but I could not findmuch onthat.
Have a great day, Alex

You should be able to compile a printf into your c++ program aslong as youinclude the header for printf which is stdio and stdlib with thehextention.

Yes, just the 34 of 16:34. The examples used printf() which is,I believe,a c function and stopped my program from compiling in cpp.
Have a great day, Alex

Hi Alex: Plese could you clarify what you want: if the time is 16:34, doyou justwant the 34? What examples did you fine? Sean.

how could I go about getting the minutes, as an integer, of thesystemtime using cpp? I tried to find it, but got what seemed to beexamplesin c not cpp. Thanks.
