The problem i am having is I have to have the heights be only 1 decimal to the right whatever your put in for instance: 55.0 4.0 i just do not know how to make just the heights 1 decimal i tried cout << fixed << setprecision(1); but that makes the dates 1 decimal too if you understand what i am trying to please help.

You shouldn't be reading in the data into a double or an integer in ddmmyy format anyway. What happens when the date is entered as 061008, which is today's date? That leading 0 is dropped in the output. If you store the date as an integer or a string, fixed << setprecision (1) won't have an effect. A date really isn't a double anyway, so store it as a string.
