Help: Display time and date

**stansu** · 08-21-2003

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?

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?

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
}
