Test Question

A program will input any interger value between 0 and 15 then the algorithm is to convert that value to binary (base2). The number input and its equivalent binary value are to be printed out.

Can anyone show an algorithm representing that?

I know it is something like...lets say if they inputed 11 in the text field it has to be divded by 2, the answer will be 5.5.....then you have to put that 5 over 2 and get 2.2? and then bahhhhh im lost any help guys?

This function takes a byte and converts it to binary:

Code:

---

Function Getbits(Invoer As Byte) As String
    Dim Uitvoer As String
   
    If (Invoer And 128) = 128 Then
        Uitvoer = Uitvoer & 1
    Else
        Uitvoer = Uitvoer & 0
    End If
       
    If (Invoer And 64) = 64 Then
        Uitvoer = Uitvoer & 1
    Else
        Uitvoer = Uitvoer & 0
    End If
       
    If (Invoer And 32) = 32 Then
        Uitvoer = Uitvoer & 1
    Else
        Uitvoer = Uitvoer & 0
    End If
       
    If (Invoer And 16) = 16 Then
        Uitvoer = Uitvoer & 1
    Else
        Uitvoer = Uitvoer & 0
    End If
       
    If (Invoer And 8) = 8 Then
        Uitvoer = Uitvoer & 1
    Else
        Uitvoer = Uitvoer & 0
    End If
       
    If (Invoer And 4) = 4 Then
        Uitvoer = Uitvoer & 1
    Else
        Uitvoer = Uitvoer & 0
    End If
       
    If (Invoer And 2) = 2 Then
        Uitvoer = Uitvoer & 1
    Else
        Uitvoer = Uitvoer & 0
    End If
       
    If (Invoer And 1) = 1 Then
        Uitvoer = Uitvoer & 1
    Else
        Uitvoer = Uitvoer & 0
    End If
   
    Getbits = Uitvoer
   
End Function

You can use it like this:

Code:

---

Msgbox Getbits(CByte(Cint(Text1.Text)))

---

He wants it to be the drawn out long way, anyone know how to do that?

The problem is he was showing it in q basic...and told us we can use any language we want to do it but cant use no short cuts have to show it step by step....I chose vb but need help i dont understand........if you dont know how to make the algorithm do you at least know the steps to convert the number? My had writing was so sloppy im lost.

More like psecode(SP)

Input 11
Divide 2
Answer 5.5
Int(5.5) = (cant read looks like Se maybe < 0)
if (5.5 = 5) >0 then
4th digit = 1
else 4th digit = 0
end if
5
- = 2.5 Int(2.5(Cant read looks like (2.5+2)
2
If 2.5 - 2 > other
3rd digit = 1
etc.

Its been a while since I've done this but try:

Code:

---

Public Function GetBits(ByVal Number As Integer) As String
 Dim I As Integer
 Dim Buffer As String

 For I = 0 To 15
  If (Number Mod (2 ^ I)) = 0 Then
  Buffer = "0" & Buffer
  Else
  Buffer = "1" & Buffer
  End If
 Next I

 GetBits = Buffer
End Function

I don't know if thats exactly right but that should give you a good start. (I hope)

I'll see what i can get out of it....do you know the steps by hand to convert a number into binary? This would help as well..... By the way Lewis....that download the first level link on your site doesnt seem to work?.......Thanks!
