daya Posted December 31, 2013 Share Posted December 31, 2013 Hi, I write Loop for summinf 1 to 10 as follow: Local $s,$i For $s = 0 to 10 step 1 $i = $i+$S Next MsgBox(0,"ANS",$i) Its works OK. But when I define Function for above For...To Loop as below.I get wrong answer. Pl just pinpoint my mistake. Func sum($k,$s) For $i = $k to $s $i = $k + $i Next MsgBox(0,"",$i) EndFunc sum(0,10) Link to comment Share on other sites More sharing options...
BrewManNH Posted December 31, 2013 Share Posted December 31, 2013 Because you reused the loop variable $i when you're doing the calculation, and not the variable $k which is what I'm assuming you were trying to do.

daya Posted December 31, 2013 Author Share Posted December 31, 2013 Thanks MVPs I rearrange code like this: Func sum($k,$s) For $i = $k to $s $k = $i + $k Next MsgBox(0,"",$k) EndFunc sum(0,10) It Gives me correct result but when I use this function having value other than Zero then it gives wrong value. i.e. sum(2,5) gives 16 istead of 13. Pl. give me some explanatory hints. Regards Link to comment Share on other sites More sharing options...
BrewManNH Posted December 31, 2013 Share Posted December 31, 2013 16 is the correct answer for that. I'll break it down for you: $k = 2, $i = 2 (2+2=4) $k = 4, $i = 3 (4+3=7) $k = 7, $i = 4 (7+4=11) $k = 11, $i = 5 (11+5 =16) $i starts at 2 and ends at 5, the results are correct. If I posted any code, assume that code was written using the latest release version unless stated otherwise.

jchd Posted January 1, 2014 Share Posted January 1, 2014 You're summing the lower bound (2) twice. If indeed you want 2+3+4+5 you should get 14.

daya Posted January 2, 2014 Author Share Posted January 2, 2014 Thanks BrewManNH Looking to that way code is correct. I want to add sum(2,5) i.e. 2+3+4+5 = 14 , it should be 14 ...not 16 or 13. Whereas sum(0,10) means 0+1+2+3+4+5+6+7+8+9+10 = 55 is correct. Why this differ. Regards Link to comment Share on other sites More sharing options...
kylomas Posted January 2, 2014 Share Posted January 2, 2014 daya, Is this what you aretrying to do? func Sum($a, $b) local $tmp = 0 for $1 = $a to $b $tmp += $1 Next return $tmp EndFunc ConsoleWrite(Sum(2,5) & @LF) ConsoleWrite(Sum(0,10) & @LF) Forum Rules Procedure for posting code "I like pigs.

daya Posted January 2, 2014 Author Share Posted January 2, 2014 Thanks kylomas Oh yes it is exactly what I am trying to do. Can you suggest me sources for practise examples for Loop, If.. and Functions. Thanks Link to comment Share on other sites More sharing options...
Solution kylomas Posted January 3, 2014 Solution Share Posted January 3, 2014 daya, There are several Wiki tutorials (Google search). After that the Help file is your best resource followed by this forum. Good Luck, kylomas Forum Rules Procedure for posting code "I like pigs. Dogs look up to us. Cats look down on us.
