Using C++, create a program that allows a user to enter characters using cin. The user can only enter these characters, A - F (A,B,C,D,E,F) and ? only. Any other character should return a message saying invalid input, and must let the user try again. The loop ends when the user enters the correct input. Use: if((grade >= 'A' && grade <= 'F') || (grade == '?')) or any other method.
I would be interested in further information on the many applications of automata theory.
The Science of Computing Mystery Mania Six men: Bill Fox, Tom Smith, Robert Stevenson, Fred Edison, Larry Davis, and John Harrison were in a library together. Suddenly, the lights went out. When the lights came back on, Bill Fox was found shot. The other detectives have investigated; questioned the suspects, the witnesses, and people who know the suspects; and have collected physical evidence from the crime scene. They have collected 14 clues but have not been able to solve the crime. It's now up to you. Note that no two suspects have the same height, color car, color umbrella, color shirt, or color shoes. The clues: • John Harrison owns a purple car Tom Smith is 5'3" tall • The suspect who was wearing a yellow shirt owns a red car The suspect who is 5'6" tall was wearing a blue shirt • The suspect who owns a red car is 6'3" tall • The suspect who was carrying a yellow umbrella is not the one who owns a green car • The suspect who is 6' tall is not the one who was wearing a black shirt…
I would be grateful if you could elaborate on the many applications where automata theory has been shown to be useful.
