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!
Ответ:
65 536 символов
Объяснение:
Юникод (Unicode) — стандарт кодирования символов, в котором один символ кодируется двумя байтами (в отличие от ASCII), что позволяет представить знаки всех языков мира. Первые 128 символов повторяют таблицу ASCII.
2 байта = 2 * 8 = 16 бит на 1 символ (1 байт = 8 бит)
Формула определения количества информации:
N = 2^i , где
N — мощность алфавита (количество символов),
i — количество бит (информационный вес символа).
i = 16 бит
N = 2^i = 2^16 = 65 536 символов в таблице
