Write a program that lets you know if you can have a key or not, based on your role at the school.
First ask for the user’s role at the school. They can be a student, administrator, or a teacher. (And remember that capitalization is important! ‘Student’ is not the same as ‘student’.)
Example 1: Administrator or Teacher
For example, if this was the input:
Are you an administrator, teacher, or student?: teacher
This should be the output:
Administrators and teachers get keys!
Example 2: Student
And if this was the input:
Are you an administrator, teacher, or student?: student
This should be the output:
Students do not get keys!
(Note: You should also be able to handle a situation where the user enters a value other than administrator, teacher or student and tell them they must be one of the three choices!)
Example 3: Other
If they input anything else:
Are you an administrator, teacher, or student?: secretary
This should be the output:
You can only be an administrator, teacher, or student!
Размер файла в котором содержится 1200 знаков равен 600 байт. Следовательно, для хранения одного символа информации требуется 600 : 1200 = 0,5 байта. В одном байте содержится 8 бит, следовательно для хранения одного символа требуется 0,5 * 8 = 4 бит.При помощи кода, состоящего из 4 бит, 2 ^ 4 = 16 символа.
(4 бита кодируют = 16 разных значений (2^4 = 16)).
Ответ: 16 — возможное количество различных символов в этом сообщении.
