Here is what I did
              
fin >> isFirst;
while (fin >> val)
fin >> val;
if (isFirst > val)
min = val
max = isFirst
else
max = val
min = isFirst

declare variable for smallest value
declare variable for largest value
set both to first value in the file
while there's more data
    read new value
    if smaller than smallest set as smallest
    else when larger than largest set as largest
wend
close file
