Question

编写一个程序来输入任何字母并检查它是元音还是辅音？

sing_ch = gets.to_c;

if(sing_ch=='a' || sing_ch=='e' || sing_ch=='i' || sing_ch=='o' || sing_ch=='u' || sing_ch=='A' || sing_ch=='E' || sing_ch=='I' || sing_ch=='O'|| sing_ch=='U')   

    
          
            print("The alphabet is a vowel.")
          
        elsif((sing_ch > 'a' && sing_ch<'z') || (sing_ch>'A' && sing_ch<'Z'))  
          
            print("The alphabet is a consonant.") 
          
        else  
          
            print("The character is not an alphabet.")
            
           
    
        end
