Looping and finding similar number in VBA - vba

Question

I am very new to VBA. Just started reading it up 2 days ago. I am wondering how could I write a VB codes assigned to a button to read through the whole column and search for similar numbers.
After that identifying similar numbers, it would need to move on to another column to check if the character in the column are same too.
If both of the logic = true . How can i change the cell of the value of another column?
Sample data
For the current example. The code should know that the first column had matching numbers. After that it will check for the name which is "a" in the example. After that it will automatically change the point to 1 and 0. If there are 3 same ones it will be 1,0,0 for the point

Answer 1

You may try recording whatever you want to do with record macros first, then filter out the codes that are not necessary. If you do not know how to record it using macros, click on the link below. You can learn from the recorded macros and slowly improvise your codes in the future from the experience you may gain.

Answer 2

As per image attached in image I am assuming numbers are in Column A, column to check characters is Column J and result needs to be displayed in Column O then try following code.
Sub Demo()
Dim dict1 As Object
Dim ws As Worksheet
Dim cel As Range, fCell As Range
Dim lastRow As Long, temp As Long
Dim c1
Set dict1 = CreateObject("Scripting.Dictionary")
Set ws = ThisWorkbook.Sheets("Sheet2") 'change Sheet2 to your data sheet
With ws
lastRow = .Cells(.Rows.Count, "A").End(xlUp).Row 'last row with data in Column A
c1 = .Range("A2:A" & lastRow)
For i = UBound(c1, 1) To 1 Step -1 'enter unique values with corresponding values in dict1
dict1(c1(i, 1)) = .Range("J" & i + 1) '+1 for Row 2
Next i
Set fCell = .Range("A2")
For Each cel In .Range("A2:A" & lastRow) 'loop through each cell in Column A
temp = WorksheetFunction.CountIf(.Range(fCell, cel.Address), cel) 'get count
If temp > 1 Then
If cel.Offset(0, 9) = dict1(cel.Value) Then
cel.Offset(0, 14).Value = 0
Else
cel.Offset(0, 14).Value = 1
End If
Else
cel.Offset(0, 14).Value = 1
End If
Next cel
End With
End Sub
EDIT
Sub Demo()
Dim ws As Worksheet
Dim lastRow As Long
Application.ScreenUpdating = False
Set ws = ThisWorkbook.Sheets("Sheet2") 'change Sheet3 to your data range
With ws
lastRow = .Cells(.Rows.count, "A").End(xlUp).Row 'last row with data in Column A
.Range("O2").Formula = "=IF(MOD(SUMPRODUCT(($A$2:$A2=A2)*($J$2:$J2=J2)),3)=1,1,0)" 'enter formula in Cell O2
.Range("O2").AutoFill Destination:=.Range("O2:O" & lastRow) 'drag formula down
.Range("O2:O" & lastRow).Value = .Range("O2:O" & lastRow).Value 'keep only values
End With
Application.ScreenUpdating = True
End Sub
