program stops after reading procedure (delphi)

My program stops to read anymore lines and ends the program after this procedure like its 'end.' after it (but its not) :

  Procedure BubbleSort;
  var i, j : integer;
  begin
    for i := 0 to count - 1 do begin
      for j := count - 1 downto i do
        if (together[j] > together[j - 1]) then
          Swap(together[j - 1], together[j]);
    end;
  end;
Solution

  • I guess the problem is the out of bounds array access. You access index -1. Avoid this by changing the outer loop to:

    for i := 1 to count - 1 do begin

    I suggest that you enable range checking so that you can learn about out of bounds array access by way of informative runtime errors.
