我使用以下代码来比较字符串,但它总是把我带到其他地方.为什么？
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
我也试过.eql？(“string”),但我得到了相同的结果.
