Question

Что будет выведено на экран в результате выполнения фрагмента программы: a := 12; b := 8 + a / 2; a := a - b / 2; write (a);

Answer 1

Ответ:

5

Объяснение:

a = 12

b = 8 + a / 2 = 8 + 12 / 2 = 8 + 6 = 14

a = a - b / 2 = 12 - 14 / 2 = 12 - 7 = 5

Answer 2

Code Explanation

The given code fragment is written in a programming language, which appears to be JavaScript. Let's break down the code and understand what it does.

a := 12;
b := 8;
a := a / 2;
a := a - b / 2;
write(a);

Code Execution

1. The variable `a` is assigned the value `12`. 2. The variable `b` is assigned the value `8`. 3. The value of `a` is updated by dividing it by `2`. So, `a` becomes `6`. 4. The value of `a` is updated again by subtracting `b` divided by `2` from it. Since `b` is `8`, `b/2` is `4`, and `a` becomes `6 - 4 = 2`. 5. Finally, the value of `a` is printed to the screen using the `write()` function.

Output

The code will output the value of `a`, which is `2`.

Please note that the code provided is not valid JavaScript syntax. The `:=` operator is not used in JavaScript for variable assignment. Instead, the `=` operator is used. Additionally, the `write()` function is not a standard JavaScript function for outputting values. It is possible that the code is written in a different programming language or is using a custom implementation of the `write()` function.
