Question

Задача в Паскале!Дано трехзначное число - X, выделите его цифры и выведите их в обратном порядке.

Answer 1

Var n:integer;
begin
  repeat
    write ('N = ');
    readln (n);
  until (n>99) and (n<1000);
 while n<>0 do
   begin
     write (n mod 10);
     n:=n div 10;
   end;
  readln;
end.

Task in Pascal: Extracting and Reversing Digits of a Three-Digit Number

To solve this task in Pascal, you can follow these steps:

1. Input the Three-Digit Number: - Prompt the user to input a three-digit number.

2. Extracting Digits: - Use division and modulo operations to extract the individual digits from the input number. - For example, if the input number is X, you can extract the hundreds, tens, and ones digits using division and modulo operations.

3. Reversing the Digits: - Once the digits are extracted, you can reverse their order and store them in separate variables.

4. Output the Reversed Digits: - Finally, display the reversed digits in the desired format.

Here's a sample Pascal code to achieve this:

program ReverseDigits;

var
  X, hundreds, tens, ones: integer;

begin
  // Input the three-digit number
  write('Enter a three-digit number: ');
  readln(X);

// Extracting the digits
  hundreds := X div 100;
  tens := (X div 10) mod 10;
  ones := X mod 10;

// Reversing the digits
  writeln('Reversed digits: ', ones, tens, hundreds);
end.

When you run this program and input a three-digit number, it will extract the digits and display them in reverse order.

This code first prompts the user to input a three-digit number. Then, it extracts the hundreds, tens, and ones digits using division and modulo operations. Finally, it reverses the digits and displays them in reverse order.
