>>>Do I still miss something?
>>That's the console asking for your name.
>>Type your name and hit enter.
>>It will ask for your age.
>>I lied and hit enter.

>Thank you. The only thing still, after I type some age, e.g. 100, the command prompt goes away. I thought it would show the line in your code that so-and-so is 100 years old.
