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!

var a,i,k:integer;
arr:Array[1.10] of integer;
begin
randomize;
for i:= 1 to 10 do
begin
a:=random(1,20);
arr[i]:=a;
end;
k:= arr[1];
for i:= 1 to 10 do
begin
k:= k — arr[i];
end;
for i:= 1 to 10 do
write(arr[i], ‘ ‘);
writeln();
writeln(‘Разность чисел — ‘,k);
end.
Объяснение:
первый цикл заполняет массив случайными целыми числами
второй вычисляет разность
третий нужен для вывода массива (необязательно но для наглядности)
