output is backwords and funtion help.

[Beauzel]

Hello everyone,

I have been working on my last homework assignment and its due tonight.
I have a few issue i need to work out with it. Fist off the output is returning in reverse order in my ending output loop. Such as values entered as 78 87 98 return as 98 87 78.

Secondly i am having trouble figuring out the last two function i need.
I need a function to determine the min value in an array (array "Avgs")and return it as well as a function to return the max value of the same array.

I am still working to figure it out but time is running out so any help is appreciated!

Thank You,
Beauzel.

Thank you very much! I was able to make the needed adjustments to get everything working and i learned a lot from your "template there".
Much appreciated!
