Question

А ну-ка. 3.Определите, что будет выведено на экран после выполнения фрагмента программы:x := 6;y := x-5;y := y-1;if (y>=0) then writeln('Ola') else writeln('Hello');4. Что будет напечатано в ходе выполнения данной программы? var a,b: integer;begina:=5;b:=a-7;a:=a-b;while (a>0) do begina:=a-2;b:=b+3;end;write(b);end. ​

Answer 1

Решение:
3. Поскольку в результате выполнения вышеперечисленных операций y будет равен 0, то на экран будет выведено сообщение: Ola
4. Выполнение действий:( a:=5; b:=-2; a:=7; Поскольку (a>0), то продолжим: a:=5; b:=1; конец)
На экран выведено значение b:
1
Ответ: 3. Ola; 4. 1

Answer 2

Output of Program Fragment:

The given program fragment initializes variables `x` and `y`, performs some arithmetic operations, and then uses a conditional statement to determine the output.

The program fragment is as follows: ``` x := 6; y := x - 5; y := y - 1; if (y >= 0) then writeln('Ola') else writeln('Hello'); ```

The output of the program fragment will be 'Ola'. Here's the breakdown: 1. `x` is assigned the value 6. 2. `y` is assigned the value of `x - 5`, which is 1. 3. `y` is then decremented by 1, making its value 0. 4. The conditional statement checks if `y` is greater than or equal to 0. 5. Since `y` is 0, the condition is true, and therefore, 'Ola' will be printed to the screen.

Output of Given Program:

The given program involves variable initialization, arithmetic operations, and a while loop.

The program is as follows: ``` var a, b: integer; begin a := 5; b := a - 7; a := a - b; while (a > 0) do begin a := a - 2; b := b + 3; end; write(b); end. ```

The output of the given program will be '1'. Here's the breakdown: 1. `a` is assigned the value 5. 2. `b` is assigned the value of `a - 7`, which is -2. 3. `a` is then assigned the value of `a - b`, which is 7. 4. The while loop iterates as long as `a` is greater than 0. 5. Inside the loop, `a` is decremented by 2 and `b` is incremented by 3 in each iteration. 6. After the loop, the value of `b` is printed, which is '1'.
