Question

I am using the following code to compare strings but it always takes me to the else. Why?

print("Enter your state abbreviation: ")
state_abbreviation = gets
if state_abbreviation.upcase == "NC"
  puts("North Carolina")
elsif state_abbreviation.upcase == "SC"
  puts("Sourth Carolina")
elsif state_abbreviation.upcase == "GA"
  puts("Georgia")
elsif state_abbreviation.upcase == "FL"
  puts("Florida")
elsif state_abbreviation.upcase == "AL"
  puts("Alabama")
else
  puts("You have enter wrong abbreviation")
end

I also have tried .eql?("string") but I get the same result.

Answer 1

The string returned by gets will have a linebreak at the end. Use String#chomp to remove it (i.e. state_abbreviation = gets.chomp).

PS: Your code would look much cleaner (IMHO) if you used case-when instead of if-elsif-elsif.
