Hi there...
the following lines
if((counter == 0) || (num[counter] > max))
max = num[counter];
is a condition that check if you are in the first element of the array then
and for that the we assuem that this first elemen is the max number we're
searching for.
"||" which mean "OR" if the current number in the num array num[counter] is
*larger* (num[counter] > max) that our previously founded max number then
its(num[counter]) becoms our new max number.
Instead of max define min variable with value 0 , and the condition shoudl
be changed accordingly -
if((counter == 0)||(num[counter] < min))
min = num[counter];
if you are in the first element of the array then and for that the we
assuem that this first elemen is the min number we're searching for. "||"
which mean "OR" if the current item(number) in the num array is
*smaller*(num[counter] <
min) than the our previously founded min number then its(num[counter])
becoms our new min number.
also you need to change the informative messages and string you type - in
order to show the minimum number.
