Ruby如果其他條件比較

Question

我有一個關於Ruby中的if else循環的問題。下面是代碼

print "Enter your age: " 
age = gets.chomp.to_i 

print "Enter your sex(M/m/F/f) : " 
sex = gets.upcase 

if (sex == "M" and age > 21) 
    puts "Hi dude. You may enter." 
elsif(sex == "F" and age > 18) 
    puts "Hi dudette. You may enter." 
elsif (sex == "M" and age < 21) 
    puts "Hi dude. You may not enter." 
elsif(sex == "F" and age < 18) 
    puts "Hi dudette. You may not enter." 
else 
    puts age 
    puts sex 
    puts "I do not recognize that sex. Enter only M, m, F, or f." 
end 

當我在輸入類型，不管是什麼我進入它只是進入其他環路部分。我已經打印出2個變量的年齡和性別進行復查，他們確實符合我列出的條件。那麼，我的變量是否存在這個問題？或者如果我還有其他條件呢？

你剛纔忘了格格添加到性別部分

print "Enter your age: " 
age = gets.chomp.to_i 

print "Enter your sex(M/m/F/f) : " 
sex = gets.chomp.upcase 

if (sex == "M" and age > 21) 
    puts "Hi dude. You may enter." 
elsif(sex == "F" and age > 18) 
    puts "Hi dudette. You may enter." 
elsif (sex == "M" and age < 21) 
    puts "Hi dude. You may not enter." 
elsif(sex == "F" and age < 18) 
    puts "Hi dudette. You may not enter." 
else 
    puts age 
    puts sex 
    puts "I do not recognize that sex. Enter only M, m, F, or f." 
end 

這工作
