Question

определить является ли число N чётным двузначным числом в паскале

Answer 1

Program is_ev_2d;
var n: integer;
begin
  write('Введите число: ');
  readln(n);
  if (n mod 2 = 0) and (n > 9) and (n < 100) then
    writeln(n, ' чётное двузначное')
  else 
    writeln(n, ' не чётное двузначное')
end.

Answer 2

Determining if a Number is Even and Two-Digit in Pascal

To determine if a number N is even and two-digit in Pascal, we can use the modulo operator to check if the number is even and then check if it falls within the range of two-digit numbers.

Checking if the Number is Even: In Pascal, we can use the modulo operator (%) to check if a number is even. If the remainder of the number divided by 2 is 0, then the number is even.

Checking if the Number is Two-Digit: To check if a number is two-digit, we can verify if it falls within the range of 10 to 99.

Therefore, to determine if a number N is even and two-digit in Pascal, we can use the following logic:

1. Check if N is even using the modulo operator. 2. Check if N falls within the range of two-digit numbers (10 to 99).

Let's put this logic into code:

function IsEvenAndTwoDigit(N: Integer): Boolean;
begin
  // Check if N is even
  if (N mod 2 = 0) and (N >= 10) and (N <= 99) then
    IsEvenAndTwoDigit := True
  else
    IsEvenAndTwoDigit := False;
end;

This Pascal function checks if the number N is both even and two-digit. It first checks if N is even using the modulo operator and then verifies if N falls within the range of two-digit numbers.

Example Usage: ``` // Example usage of the function var Number: Integer; begin Number := 24; if IsEvenAndTwoDigit(Number) then writeln(Number, ' is even and two-digit') else writeln(Number, ' is not even and two-digit'); end; ```

By using this function, you can easily determine if a number N is both even and two-digit in Pascal.
