Display current time in command prompt with update

I would like to know how I display the current type in the command prompt so that it updates itself to show the changing time.

Thanks.

bump...

Still need an answer...

using windows?

Code:

---

int main()
{
        while( true )
        {
                SYSTEMTIME SystemTime;
                GetSystemTime( &SystemTime );

                system("cls");
                cout << SystemTime.wHour << ":" << SystemTime.wMinute << "." << SystemTime.wSecond;
                Sleep( 1000 );
        };

        return 0;
}

What library are you using?

I know it is not <ctime>.

Using mwilliamson's idea, here is another method. This one just moves the cursor back to the beginning of the current line without erasing the entire window.

Code:

---

int main(int argc, char* argv[])
{
        while( true )
        {
                SYSTEMTIME SystemTime;
                GetSystemTime( &SystemTime );

                cout << "\r" << SystemTime.wHour << ":" << SystemTime.wMinute << "." << SystemTime.wSecond;
                Sleep( 1000 );
        };

        return 0;
}

If you do that, when you switch from 12:59.59 to 1:00.00 then you will not overwrite all of the characters making your output 1:00.009.

#include <windows.h>

that's easy to fix. just add some more spaces at the end

Code:

---

int main(int argc, char* argv[])
{
        while( true )
        {
                SYSTEMTIME SystemTime;
                GetSystemTime( &SystemTime );

                cout << "\r" << SystemTime.wHour << ":" << SystemTime.wMinute << "." << SystemTime.wSecond << "    ";
                Sleep( 1000 );
        };

        return 0;
}

thats a mess... lets just use cls :)

if you use cls you erase the entire screen -- there may be other stuff on the screen that you don't want erased. it would also cause a flicker affect.

Thanks guys!

I was trying to time the execution of a program using constant time update. That won't work in the DOS console however.

I will simply display the time before and after execution of the code. :)
