Ive already think a lot but I still cant find an equation that will give the Largest and Smallest number on the list. Can anyone help me please. Thanks a lot.

var value, sum, average : real
var howMany : int

sum := 0

put skip, "Enter how many numbers in your list: " ..
get howMany

put "OK - enter all the numbers:"

% Counted loop - get each value and add it to the sum
for i : 1 .. howMany
get value
sum := sum + value
end for

% Compute the average
average := sum / howMany

put skip, "The average is ", average : 7 : 1, skip

To find largest and smallest numbers in the list, you gotta sort them.

The easiest to understand (and most unefficient Wink ) is bubble sording. You probably heard of it before.

Its a series of loops that compares the numbers and swaps them if one is larger then other. At the end you'll end up with largest number in the list. And if you sort all of it, the first number would be the smallest.

code:

For i=1 to sizeOfList - 1
if num(i) > num(i+1) then
temp = num(i)
num(i) = num(i+1)
num(i+1) = temp
end if
end for


Code above should bubble up the largest number to be num(sizeOfList).

num() is ofcourse an array... just to make sure we're on the same book Wink
