Android Question For Loop Statement

Jimpin23 · May 30, 2020

For Loop statement that loops the numbers from 1-100 and determines all numbers Divisible by 3. Is my code correct?
Sub bt1_Click
Dim Num,Res As Int
Num = 0
Res = 0
For Loop Res
Res = Num % 3
Num = Num + 1
Loop
Bt1.Text = “Done”
End Sub

Just beginner hehe

Here is what your code should be:

B4X:

For i=1 To 100
    If i Mod 3 =0 Then
        Log(i)  'show only numbers divisible by 3
    End If
Next

You need to use code tags when you post code to make it wasy to read.

No big deal. I just thought I mention the code tags to you now before you hear it from Erel, but it is understandable in your case as you just started with the forum.

Why don't save "time and money" by using

Loop:

For i=0 To 100 Step 3
   Log(i)
Next

In this code you don't have to waste your time on useless iterations.

So you will get

0
3
6
and so on
