« on: August 24, 2025, 08:35:03 pm »
Code: Pascal  [Select][+][-]
  1.  i:= 0;
  2.  number := 0;
  3.  for i := number to (number+1) do
  4.  begin
  5.          
  6.  end;
  7.  

it executes twice but i is in both cases 0 ?

If the compiler determines that the value of I is not used, it can optimise it. If you then look with the debugger, the value doesn't make sense, but that is not really a problem.

What did you exactly do to test ?

Put breakpoint, check i value that I'm using inside loop.

EDIT: ahh, my bad. Thanks for opening my  eyes (-: number and i switched places in my brain.
