o Here is a Pascal program:

  program howold;

  var
    age : real;
    years : integer;

  begin
    write('Enter your age (e.g., 23.5): ');
    readln(age);

    years := age;  { just get # of years }

    writeln('You are ', years, ' years old');
  end.

o There is an error in this program, what is it?

o Bonus: Is this error a syntax or semantic error?

o What is a "nested" loop?

o A nested loop has an outer loop and an inner loop:

    Outer Loop {
      .
      .
      .
      Inner Loop {
        display 'Hello'
      }
      .
      .
    }

o Assume that the outer loop is done 3 times and that
  the inner loop (when looked at by itself) is done
  5 times.  How many times is 'Hello' displayed?

o Write this loop in Pascal.

o Write a nested loop where the inner loop is done
  first once, then twice and finally, three times.
