Sum multiples of 3 and 5 is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
The objective is to find the sum of multiplies of 3 or 5 below n within a function. Test it with n = 1000.
BASIC
I'd suggest to change s += 1 to s += i
REXX also finds 467 numbers
<lang basic>Declare function mulsum35(n as integer) as integer
Function mulsum35(n as integer) as integer
Dim s as integer For i as integer = 1 to n If (i mod 3 = 0) or (i mod 5 = 0) then s += 1 End if Next i Return s
End Function Print mulsum35(1000) Sleep End</lang>
- Output:
467
Perl 6
<lang perl6>sub sum35($n) { [+] grep * %% (3|5), ^$n; }
say sum35 1000;</lang>
- Output:
233168
REXX
<lang rexx>/* REXX ***************************************************************

Say mul35() exit mul35: s=0 Do i=1 To 1000
If i//3=0 | i//5=0 Then s=s+i End
Return s</lang> Output:
234168
