Using an array would probably help. I'm assuming the numbers are in a file, right? So what is it, exactly, that's so confusing?
avg
30.5
11.3
12.3
8.6
9.9
27.5
8.3
12.6
3.9
9.8
this are the numbers that i will get the average!
he say's that the output will be on the file and on the screen!

can you give me an example of fstream program for this problem Plz so that i can have a way on doing other problems! :<
I'd rather not just give you the answer to the problem, but here's a fiveline pseudocode program of what to do:
[code]
open the file
read all of the data in the file into an array of size 10
set q = (array[0] + array[1] + array[2] + array[3] + array[4] + array[5] + array[6] + array[7] + array[9]) / 10
print q to the standard output
write q to the input file
[/quote]
So, where specifically is your problem?
