Help: Display time and date

Hi everyone,

can someone tell me how to write a program to display the current time and date, and copy to a text file whenever the program executed?

Thanks

Look up some information on file I/O and C++'s built in time and date functions.

Code:

---

<time.h>
<fstream.h>

---

Read some tutorials on those. Read the libraries themselves.

Oh, and have fun :)

create a new win32 console application

insert this code in it.

Code:

---

    // we need the time and date
        CTime t = CTime::GetCurrentTime();

        // date
        cout << "Date: " << t.GetYear() << "-";
        if (t.GetMonth()<10)
                cout << "0";
        cout << t.GetMonth() << "-";
        if (t.GetDay()<10)
                cout << "0";
        cout << t.GetDay() << "\r\n";
        // time
        cout << "Time: ";
        if (t.GetHour()<10)
                        cout << "0";
        cout <<  t.GetHour() << ":";
        if (t.GetMinute()<10)
                        cout << "0";
        cout <<  t.GetMinute() << ":";
        if (t.GetSecond()<10)
                        cout << "0";
        cout <<  t.GetSecond() << "\r\n";

        getch();

you will need to include the proper library if the compiler ask for it.

Isn't CTime part of MFC. If it is you will also need to go to project -settings and select USING MFC IN STATIC LIBRARY. You will also have to include afxwin.h

Since when did the question concern MFC?

Not a single mention of MFC or even Windows. In the absence of such mention, let's try and stick with something portable, kay? :)

Code:

---

#include <iostream>
#include <fstream>
#include <ctime>

using namespace std;

int main(int argc, char *argv[])
{
    if (argc == 2) {
        ofstream log(argv[1]);

        if (!log)
            cerr<<"Logging disabled\n";
        else {
            time_t present = time(0);
            log<< ctime(&present) <<endl;
            log.close();
        }
    }
    else if (argc > 1)
        cerr<<"usage: $"<< *argv <<" <logfile>\n";

    // Rest of the program
}

And, there's more date & time info in the Programming FAQ!
