Question

Чему будет равно значение целой переменной «a» после выполнения этого фрагмента программы? a = 2 for i in range(5): a += i Введите число: * 10 12 8 9

Answer 1

Ответ:

12

Объяснение:

цикл выполнится 5 раз

i будет принимать значения 0, 1, 2, 3, 4

а = 2 (начальное значение) + 0 + 1 + 2 + 3 + 4 = 12

Answer 2

Value of Variable "a"

After executing the given code fragment, the value of the variable "a" will be 4.

The code `a += i` is equivalent to `a = a + i`. Therefore, for each iteration of the loop, the value of "a" will be updated by adding the current value of "i" to it. Here's a breakdown of the iterations: 1. Initially, "a" is 2. 2. When i is 0, a = 2 + 0 = 2. 3. When i is 1, a = 2 + 1 = 3. 4. When i is 2, a = 3 + 2 = 5. 5. When i is 3, a = 5 + 3 = 8. 6. When i is 4, a = 8 + 4 = 12.

Therefore, after the loop, the value of "a" will be 12.
