Question

In the software RUBY

Create

• The first method, unsafe? will take in an argument of a speed and return true if the speed is unsafe and false if it is safe.
  • Use an if/else statement pair to build the unsafe? method. It should return true if the speed is either below 40 or above 60. Going 30 mph on the freeway would be unsafe, as would going 95 mph. Going 50 miles per hour, however, would return false as that's within the "safe" range.
• Build the method not_safe? that is a version of your previous unsafe? method but use the ternary operator (?:) instead of an if/else statement pair.

Answer 1

RUBY Code:

Using if-else:

def unsafe(speed)
   # If Else
   if speed < 40 || speed > 60
       return true
   elsif
       return false
   end

end
puts unsafe 50
puts unsafe 95

Sample Run:

$ruby main.rb false true 1 - def unsafe( speed) 2 # If Else 3 if speed < 40 || speed > 60 4 return true 5 end 6 return false 7 end 8 puts unsafe 50 9 puts unsafe 95

Using Ternary Operator:

def not_safe(speed)
   # Ternary Operator
   return ((speed < 40 || speed > 60) ? true : false);
end

puts not_safe 50
puts not_safe 95

Sample Run:

$ruby main.ro false 1. def not_safe(speed) 2 # Ternary Operator 3 return ((speed < 40 || speed > 60) ? true : false); 4 end 5 6 puts not safe 50 7 puts not_safe 95 true
