Error message when creating a structure

I am not very good at this, and can't see what I am doing wrong.

I'm supposed to make a function that takes in a structure "date", and returns it like this : 20.05.1990. This is what I have:

date = struct('day',20,'month',05,'year',1990)

function   print_date(date)

   fprintf ('%i.%02.0f.%01.0f', date.day , date.month , date.year);

end

Now I am supposed to make a new structure where one of the fields calls this function:

person = struct('name','per', 'phone', 48151623, 'day_of_birth', print_date(date))

I then get the error message: too many output arguments. What am I doing wrong? I am not allowed to use built in functions.

You have defined your function print_date to output a string to the command line window, and to return no values. However, you then use print_data(date) in a context that implies it is to return a value that will be inserted into the struct() you are creating.

Hint: sprintf()

Finally got it right! Thank you!
