}

Pascal

for vI:= 20 to 200 do
  begin
      ...
      if vI = vA then break; // Si la condition est vérifiée, la boucle se termine
      ...
  end;
 
  // Variante DownTo
  for vI:= 200 downto 20 do

break sort de la boucle

Code

   a := 10;
   while  a < 20 do
 
   begin
      writeln('value of a: ', a);
      a:=a +1;
      if( a > 15) then break;
   end;

Résultat

value of a: 10
value of a: 11
value of a: 12
value of a: 13
value of a: 14
value of a: 15

continue retourne au début de la boucle :

Code

   a := 10;
   repeat
      if( a = 15) then
      begin
         a := a + 1;
         continue;
      end;
      writeln('value of a: ', a);
      a := a+1;
   until ( a = 20 );

Résultat

value of a: 10
value of a: 11
value of a: 12
value of a: 13
value of a: 14
value of a: 16
value of a: 17
value of a: 18
value of a: 19
