Shibin, Please don't create duplicate threads. We have deleted the other one.

As far as the answer is concerned (unless this is a trick question), one of the methods can be by putting this for loop in a function and making the lower and upper index as variables. So you can have something like

PHP Code:

Function loop_iteration(lower,upper)
...
End Function

if you wish to skip say nth iteration you can 

Call (lower, n-1)
Call (n+1, upper) 


Others - please contribute your solutions as well.

Thanks for the reply... i hope this is something like writing a loop for 2 times by avoiding the iteration which is not required.. m not sure whether my interviewer want the same...

thanks again...

Sorry if my reply is so stupid....

if the requirement is not to use 'IF' and 2 for loops...

i will do something like this

Code:

For iterationNo =1 to 100
      Select Case iterationNo
        Case N    ' condition to be skipped
                'Skipping
        Case Else
                ' continues
     End Select
Next
