    Thumbs up ctime - advice needed !!!!!

    Hi all,

    I'm learning C++ from a textbook and got stumped by an exercise asking for a constructor capable of using the current time from the time and localtime functions in <ctime> in a class called Time.

    So far I've been playing around and formulating a plan to find the answer, here's what I have so far:

    Code:
    #include <iostream>
    #include <ctime>
    using namespace std;
    
    int main()
    {
        time_t t;
        t = time( NULL );
        cout << "Number of seconds passed since Jan. 1, 1970: " << t << endl;
        cout << "Number of minutes passed since Jan. 1, 1970: " << t / 60 << endl;
        cout << "Number of hours passed since Jan. 1, 1970: " << ( t / 60 ) / 60 << endl;
        cout << "Number of days passed since Jan. 1, 1970: " << ( ( t / 60 ) / 60 ) / 24 << endl;
        cout << "Number of years passed since Jan. 1, 1970: " << ( ( ( t / 60 ) / 60 ) / 24 ) / 365 << endl;
    } // end main
    That's relatively easy, but how on Earth do I work out the months?

    You need to look at the struct tm component of the ctime lib and also the localtime() function.
