Using fcanf to get parts of a text file

So I have a .txt file that is declared as fin, and I need to use fscanf to designate parts of the file to certain variables.

The file looks like this:

Farley: 46.5/7.1
L. J. Cool: -39.2/27.25

I need to create an fscanf statement that will read a single line, storing the name (including the space if present, but not the colons) in a character array name, and the two floats into the already declared variables x and y.

How would I pull thiss off?

I tried:
fscanf(fin,"%s %f %f", name, x, y);
But the exam proctor told me I was wrong without any reason...help please.

Maybe this can help you.
It's for scanf, but they will work for fscanf too.

I don't know if this is the best solution, though.

Edit: And you can also consider using the suggestion at the end of the linked page.

Firstly fscanf() takes pointers and fills them.
Secondly you always should check the return value. This tells you how many fields were successfully converted.

Thirdly, I would start with a line like

singlestring 1.5/2.5

get that working. Then look at the scanf() documentation as see if you can work out how to use a colon instead of a space as the field separator for the string.
