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!

#include <iostream>
using namespace std;
int main()
{
int k, a;
cin >> k;
a = k % 7;
if (a == 0) {
cout << «7» << endl;
}
else {
cout << a << endl;
}
return 0;
}
Объяснение:
Вроде решила верно. Мы добавляем переменную а — это остаток от 7 дней.(Например 15 делим на 7, остаток 1) Если остаток 0(например 14 делим на 7), значит это 7 день недели и, чтобы у нас не вышло 0 вместо 7 дня нужно добавить if (если). Мы делим на 7 так как это неделя. Если у нас остаток больше 0, то сразу выводим этот остаток.(Например 17 день поделить на 7, остаток 3 — это и есть день, который мы ищем). Надеюсь мои объяснения понятны :)
