[Pgubook-readers] Programming from Grown up

[Chia-Hung Huang]

Hi there

I am currently reading the book. When I finished first 3 chapters, i was trying 
to write a similar program as "findiing the maximun number. However, I want my 
program to not only find the maximun but also the minimun. Anyway, when I run 
my program and tried to output the two numbers, the program always gave me the 
maximun. 

---------------------------------------------------------
For example.

     1st echo $?
         the maximun
     2nd echo $?
         0
-----------------------------------------------------------

My question is how can I use "echo $?" to give me both max and min, and how can 
I define a string of number of positive and negative numbers. Can you give me 
some advice ?

Best regard.

ps. I work under the linux OS. And the attached file is my program.
