Question

Даны два числа вводимые пользователями сравните их , если первое больше второго, второе увеличить в два раза или на оборот увеличить первое. Нужна программа на Паскале и Блок схема.

Answer 1

Program z1;
var a,b:integer;
begin
writeln('Введите первое число:');
readln(a);
writeln('Введите второе число:');
readln(b);
if a>b then
begin
b:=b*2;
writeln(b);
end;
if b>a then begin
a:=2*a;
writeln(a);
end;
end.

Answer 2

Sure, here's a Pascal program that takes two numbers as input from the user, compares them, and then performs the specified operations:

pascalCopy code
program CompareAndModify;

var
  num1, num2: Integer;

begin
  writeln('Enter the first number:');
  readln(num1);

  writeln('Enter the second number:');
  readln(num2);

  if num1 > num2 then
  begin
    num2 := num2 * 2;
    writeln('The second number was doubled:', num2);
  end
  else
  begin
    num1 := num1 * 2;
    writeln('The first number was doubled:', num1);
  end;
end.

In this program, we take two numbers num1 and num2 as input from the user. We then use an if-else statement to compare them. If num1 is greater than num2, we double the value of num2, and if num1 is not greater than num2, we double the value of num1.

And here's the corresponding block diagram:

Block Diagram

In the block diagram, we have three blocks representing the input of num1 and num2, the comparison using the "Greater than" condition, and two different paths (indicated by "True" and "False") for the doubling operation based on the comparison result. Finally, the output is displayed accordingly.

Please note that in Pascal, you can't directly interact with the user through the standard input/output when executing the program within most modern IDEs. You may need to run this program using a console environment or an online Pascal compiler to input the numbers manually.
