Alright,
Ive been working this assignments for a few days now and got stuck on
a small section of it.So this small problem, which you may laugh at,
is as follows.

The section asks for me to read lines from a file so I can calculated
the average and median etc.

For example the input file looks like this:
1 2 3 4 5
6 7 8 9 10
etc..... and so on

I understand the read concept enough so that I can only read the first
line in the file. And I understand the wc command returns the number
of numbers in the file(to compute the average).

However,

1) Problem 1: I cant seem to be able to read any lines other than
first.

2) Problem 2: I dont know how, after reading the lines, to split the
numbers up so I can calculate the average of line 1, line2 etc........

Hopefully you can assist me in this.
Thanks
