yes or no

is it possible to use an or statement for something like a yes or no answer like

Turing:

if answer="yes" or "no"
then

is this possible or am i just being stupid?

RE:yes or no

Tony, I think he means 'if A = b or C'

You have to type 'A' twice.

So, it would look like so;

code:

if answer = "yes" or answer = "no" then
%whatever
end if

However, it seems quite illogical to have yes or no in the same one I would split it out. 'elsif' is your friend here.

code:

if answer = "yes" then
%whatever
elsif answer = "no" then
%whatever else
end if

There is also the 'else' command. Basically, if it isn't any of those things, do this.

code:

if answer = "yes" then
%whatever
elsif answer = "no" then
%whatever else
else
put "this happens if answer doesn't equal yes or no"
end if

the hint was that "no" is not a boolean expression.

perhaps he doesn't know even what a boolean expression is, Tony. You have to remember that these kids no almost nothing about programming or even things as obscurely related to it as boolean expressions.
