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!

Количество бит на 1 символ i=I/k
I — информационный объем сообщения ( бит), k — количество символов
i=5,5*1024*8/4096= 11 бит
Мощность алфавита N=2^i = 2 ¹¹ = 2048 символов

Объяснение:
Дано:
K = 4096
I = 5,5 Кб
Найти: N
Решение:
I = K * i
i = I/K
I — Нужно перевести в биты.
5,5 Кб = 45056 бит
i = 45056/4096 = 11
N = 2∧i (Два в степени i)
N = 2∧11 = 2048
