    timer

    hello, i know this has been posted many times, and i have read all of the other threads.
    what i want to do is count down in seconds from 10 to 1 and display it on screen. (just as an example)
    But, i dont want to use the sleep function, because its not portable.
    i have recently read somewhere how to do it. But i cant remember where!

    please help.

    Now I know what doesn't work.

    looks like i will have to use sleep() then, as for the portable solution kills the computer.

    but when i put the code:

    Code:
    #include <iostream.h>
    #include <windows.h>
    
    int main()
    {
    for(int c=0;c<10;c++)
    {
    	cout<<c;
    	Sleep(10);
    }
    return 0;
    }
    it just waits for 10 miliseconds an then writes 123456789 all at the same time, instead of waiting 10 miliseconds each time through the loop?

    10 milliseconds is one hundreth of a second, not a long time! Try a larger value like a thousand(one second).

    Flush the buffer after each character:
    Code:
    cout<<c<<flush;
    My best code is written with the delete key.

    cheers, works great.
    what exactly does 'flush' do?
    does it just empty the contents of a variable?

    >what exactly does 'flush' do?
    It forces the output to be written to a device (in this case the screen) immediately. Otherwise your program would wait to flush the buffer until it was full, or something else caused a flush (such as endl) for performance reasons.
    My best code is written with the delete key.

    something I've been wondering: how do you know how big the buffer is (just curious)
