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!
V = K * I, где
V — объем;
K — размер изображения;
I — количество бит на символ.
N = 2^i, где
N — количество цветов.
V = K * I .
I = V/K = (2*2^13) / (50 * 100) = 2^14 / (2 * 25 * 25 * 2^2) = 2^14 / (2^3 * 25^2) = 2^11 / 625 = 2048 / 625 = 3,2768 ~ 4 бита.
N = 2^i.
N = 2^4.
N = 16 цветов.
