The complete numbers

NEED HELP WITH A HOMEWORK PLEASE

Complete numbers: Are numbers such as 6 that equals 3 + 2 + 1 (the sum of numbers it divide to).

Ok I should write a program that request a number from the user and then tells him if the number is a complete number or no, I should be using "FOR" function and ofcourse the "IF".

Thanks for help

i really don't understand your question. What you need to do is write a program that will factor a number.Complete numbers (Perfect numbers)
The sum of factors is the original number.

6 : { 1 2 3 }, 1 + 2 + 3 = 6
28 : { 1 2 4 7 14 }, 1 + 2 + 4 + 7 + 14 = 28
496
8128
33550336
...

and then sum the factors.

To help you get started you need to take the number entered and divide it in half.

for counter = 1 to halfnumber
if number mod counter = 0 then
'counter is a factor so store it in an array
end if
next counter
now you just need to add the array values and if it equals the number then it it is a perfect number.

VB Code:

Public Function PerfectNumber(ByVal Number As Long) As Boolean
Dim laFactor() As Long
Dim lDenom As Long
Dim lCounter As Long
Dim lSum As Long
    
    'Perfect Numbers must be even
    If Number Mod 2 = 1 Then Exit Function
    
    'Seed the array with the values 1 + 2
    ReDim laFactor(0 To 1)
    laFactor(0) = 1
    laFactor(1) = 2
    
    'Loop through all number fro 3 to the mid-point
    For lDenom = 3 To CLng(Number / 2)
        
        'If the number is a factor..
        If Number Mod lDenom = 0 Then
            
            '..add it to the array
            ReDim Preserve laFactor(UBound(laFactor) + 1)
            laFactor(UBound(laFactor)) = lDenom
        End If
    Next lDenom
    
    'Sum up the factors
    For lCounter = 0 To UBound(laFactor)
        lSum = lSum + laFactor(lCounter)
    Next lCounter
    
    'If the sum of factors equals the number
    'It is Perfect
    PerfectNumber = (lSum = Number)
End Function
