Outputting time into sections

-----------------------------------

(I'm using dev-C++ 4.9.9.2)

Hi, I'm new here (obviously :P) but my background isn't important :P...

I just started learning C++ right now at university and one of my tasks is to create a program that takes in speeds (in km/h) and distances (km) and uses these to find the time taken to travel the distance. This part isn't terribly hard because all it requires is simple arithmetic functions... My only gripe right now is that I have to output the time into the following format:

hh : mm : seconds (to one decimal place)

So as of now I'm stuck and just need a nudge in the right direction or even if someone is willing to tell me exactly how to do it I'm all ears (eyes? O_o)

Cheers

Hmm, well this sounds doable. I think I might be able to help if you post some of your code.

do your calculations in seconds, then 1h == 60m, 1m == 60s. and precision can be set with the setprecision function. Google it for more info as I do not recall exact parameters.
