Check for boolean status in ruby

Ruby
1

Hi all,
I have to check for a boolean condition, and see whether its
true or false to continue running a method.
Not sure how to implement this in Ruby…

Dummycode–

boolean islogged_in = false; # set default boolean value false

for i in 0..2

RUN FUNCTION A

boolean islogged_in = true # Setting boolean to True after successful
FUNCTION A

RUN FUNCTION B

end

For First Iteration, FUNCTION A should run, but for next Iteration
onwards, only if System is not logged in FUNCTION A should run else
directly FUNCTION B should Run.
How do i set a check in Ruby or should i use some other logic other than
boolean to do this.

if islogged_in
run_function_a
else
run_function_b
end

And of course inside the function you must set the
islogged_in flag to true or false, depending on your
conditions.

This is the same in almost every programming language,
are you absolutely new to programming?

This is pretty straightforward procedural code, imo. Perhaps I’m
misunderstanding what you’re wanting?

def function_a
puts ‘a was run’
end

def function_b
puts ‘b was run’
end

logged_in = false

using 3 because 0…2 iterates over [0, 1, 2]

but we don’t actually care about the values

3.times do
function_a unless logged_in
logged_in = true
function_b
end

>> a was run

>> b was run

>> b was run

>> b was run
