for loop: example C

program forloopC;

{
  This program demonstrates another "for" loop.  It uses
  the loop to print out the numbers from m to n, where m
  and n are entered by the user.
}

var
  m, n : integer;  { start at m, end at n }
  i : integer;     { looping variable }

begin
  write('Start at: ');
  readln(m);

  write('End at: ');
  readln(n);

  for i := m to n do
    writeln(i);
end.

Below we show a compilation and run of the program.
