Question

write
a programmer-defined function named descend() that receives three integer numbers. Then, the
function prints the numbers in descending order. A sample run of the program might look as follows:
Enter three numbers: 1 -2 4
Descending order: 4 1 -2

Answer 1

It could have the following algorithm
```
function swab (a: int , b: int)
temp = a
a = b
b = temp
return a, b

function decend
print 'Enter three numbers:'
n1= input an integer
n2= input an integer
if n1 < n2
swab(n1, n2)
n3= input an integer
if n3 > n1
swab(n3, n1)
swab(n1, n2)
else if n3 > n2
swab(n3, n2)
print n3, n2, n1
```

Answer 2

Oh, and end with a return if needed

Answer 3

I've never heard of any programming language with functions which can return 2 results..

This should work:

```
function descend(a, b, c)
number first, second, third //declare 3 variables
if a >= b then {
first = a
second = b
} else {
first = b
second = a }
if c >= first then {
third = second
second = first
first = c
} else if c >= second then {
third = second
second = c
} else {
third = c }
Output ("Descending order : ", first, second, third)
```
