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:
а) true
b) true
Объяснение:
а) And — логическое умножение. 20 больше 17? Да. Поэтому a начинает принимать значение true (1). 28 равно 28? Да. Значит, b — true (1). Умножая 1 на 1, мы получим 1, то есть true.
b) Так же решается и это задание. a — true (1), b — true, так как 28 > 22 (1), с — true (1, по условию). 1 * 1 * 1 = 1, что есть истина (true).
