    Help With Time Plzzz!!

    First of all I am relatively new to programming, and I need to know how to access the system's time, in hour, minute, second, and so on. Please help me with this... I think I need to #include
    <time.h>, or is it <sys\time.h>, or am I way off base?

    <ctime> (or time.h if you will) would be where to go, yes.

    Then check this site out. It has a list of the functions and how to use them:

    Thankyou, however I'm not sure that's what I'm looking for. I went to the site, but
    That would require complex math to convert the number of seconds since midnight,
    Jan 1, 1970 into current hour, minute, and second. I would appreciate any further help
    on the subject.

    An example
    Code:
    #include <ctime>
    #include <iostream>
    using namespace std;
    int main()
    {
    	time_t example;
    	struct tm  * part2;
    	time(&example);
    	part2 = localtime( &example );
    	cout << part2->tm_hour << "\n"; //example of displaying single part of the time
    	cout << asctime(part2); //displaying all of the time
    }

    You gotta look at all the functions in <ctime> before you decide they don't work. That site has good examples, as well.

    I did look at everything that seemed useful. I wanted to access hour, minute, and second
    individually, not all at once or in a string or have to convert ten billion seconds into
    minutes or hours, or any other nonsense. Which example did you think would work for
    what I sought? Tell me and I'll check it out. Thanks...

    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*
