{ Making decisions in a Pascal program often involves the
  if-then statement or the if-then-else statement.  Here
  is an example of its use.
  
  1. Try this program with a bunch of different pairs of input
  numbers.  Each time, try to figure out ahead of time exactly what
  output you will see.
  
  2. One message asks "What do I know about that first number?"
  If that message appears, what _do_ you know about the first
  number?
}


program ifThenElse(input,output);

var	a, b : integer;

begin
	write( 'Please type two integers separated by a space: ' );
	readln( a, b );
	
	if a > b then
		writeln( 'That first number is big!' )
	else
		writeln( 'What a small first number!' );
		
	if a < 0 then
	begin
		writeln( 'Wow.' );
		writeln( 'That first number is negative.' )
	end
	else
	begin
		if a = 0 then
			writeln( 'The first is 0, my favorite number.' )
		else
			writeln( 'What do I know about that first number?' )
	end;
	
	if (a = 0) and (b = 0) then
		writeln( 'Pure Nothingness.  Cool.' );
	
	if b <> 7 then
		writeln( 'I wish the second number were 7.' )

end.
