Question

Дано ціле трьохзначне число, яке складається з неоднакових цифр. Визначте, яка з його цифр більша: перша чи друга. Як правильно написати програму на Паскалі?

Answer 1

Var a,b, d:integer;
begin
read (d);
a:=d div 100;
b:=d div 10 mod 10;
if a>b then Write ('перша більша') else Write ('друга більша')
end.

Answer 2

I can understand and communicate fluently in Ukrainian.

I will try to answer your question in detail. Given a three-digit integer that consists of different digits, determine which of its digits is larger: the first or the second. How to write a program in Pascal correctly?

To compare the first and second digits of a three-digit number, you need to extract them from the number using arithmetic operations. The first digit can be obtained by dividing the number by 100 and taking the integer part. The second digit can be obtained by dividing the number by 10, taking the remainder, and then dividing it by 10 again and taking the integer part. For example, if the number is 123, then the first digit is 123 div 100 = 1 and the second digit is (123 mod 10) div 10 = 2.

To write a program in Pascal that compares the first and second digits of a three-digit number, you can use the following algorithm:

- Declare three variables of integer type: a, b, and d. - Read the value of d from the user input. - Assign the value of d div 100 to a. - Assign the value of (d mod 10) div 10 to b. - If a is greater than b, then print "перша більша" (the first is larger). - Otherwise, print "друга більша" (the second is larger).

The program code in Pascal can look like this:

var a, b, d: integer;
begin
  read(d);
  a := d div 100;
  b := (d mod 10) div 10;
  if a > b then
    write('перша більша')
  else
    write('друга більша');
end.

You can find more examples and explanations of how to work with digits of a number in Pascal on these websites. I hope this helps you with your homework. Have a nice day!
