Oh, I thought you would have received one. Then read the Read Me threads at the top of this board -- I just finished adding a new one that shows how to use code tags.

giving me an error on line 10 saying invalid initializer

Ancient Dragon · Dec 4th, 2007, 5:41 PM

It need braces, like this

(Toggle Plain Text)

int myArray[100] = {0};

And delete line 12.

what about now?

Simplesouljah · Dec 4th, 2007, 6:02 PM

my outfile should print

The maximun value is ---- found at array ----
The minimum value is ---- found ar array ----
There are --- values---

I'm not understanding what I'm doing wrong....
what do I use to read the input infile?
