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!
Program n_1;
var a, b, i, n: integer; c: boolean;
begin
c:=true;
read(n, a);
for i:=2 to n do begin
read(b);
if b>=a then c:=false;
a:=b;
end;
if (c=true) then writeln(‘Поседовательность убывающая’)
else writeln(‘Поседовательность не является убывающей’);
end.
Это для строго убывающей последовательности. Если требуется для невозрастающей — замени if b>=a then c:=false; на b>a then c:=false;
