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!
Итак начнем.
1)Объем нашей свободной памяти 5,25 Мбайта, следовательно 5,25= 5,25 *1024 Кб = 5,25 * 1024 * 1024 БАЙТ = 5505024
Объем файла длительность которого равна t секунд 8 бит * t секунд * 44,1 кГц= 2 байта * t секунд * 4110.
44100 t = 5505024 .
t= 5505024/44100= 125 секунд.
2)Используем формулу для того чтобы найти объем нашей звуковой информации.
V=M-I-t.
M=22.05- 1000 = 22050 Гц
t=10 секундам.
V=22050 — 10-1= 22050 Байт
Надеюсь я помог.
