Answer 1

Co‎de: [in Python language]

[tex]\tt while\ True:\\ {\ \ \ \ \ }a\ =\ in put("Enter\ a\ letter:\ ")\\ {\ \ \ \ \ }if\ a\ in\ "AEIOUaeiou":\\ {\ \ \ \ \ }{\ \ \ \ \ }print("It's\ a\ vowel.")\\ {\ \ \ \ \ }else:\\ {\ \ \ \ \ }{\ \ \ \ \ }print("It's\ not\ a\ vowel.")\\ {\ \ \ \ \ }print()\\ {\ \ \ \ \ }c\ =\ in put("Enter\ '1'\ if\ you\ want\ to\ quit\ or\ any\ other\ number\ to\ continue:\ ")\\ {\ \ \ \ \ }print()\\ {\ \ \ \ \ }if\ c\ ==\ "1":\\ {\ \ \ \ \ }{\ \ \ \ \ }break\\ {\ \ \ \ \ }else:\\ {\ \ \ \ \ }{\ \ \ \ \ }continue[/tex]

Explanation:

We use a $\tt while$ loop to keep the program running. The letter is retrieved and stored into the variable 'a', using the $\tt in put()$ function. We then use a conditional statement to check if the letter is a vowel or not. After the appropriate message is displayed, we use another variable, 'c', to store the response of the user as to whether or not he/she wants to continue. The value of 'c', is again tested using a conditional statement and the program continues accordingly.

Answer 2

The program has been attached above. Kindly check it!

After typing any number other than 1, this program will run as long the given statement (u==0) is true.
