Question

Начало N = 15; N = N + 12; N = N * 3; конец. Начало N =2; N = N * 25; конец

Answer 1

1. 15
2. 15+12=27
3. 27*3=81

1. 2
2. 2*25=50

Answer 2

Code Explanation

The given code consists of two parts. Let's analyze each part separately.

# Part 1: N = 15; N = N + 12; N = N * 3;

In this part, the variable `N` is initialized with a value of 15. Then, the value of `N` is updated by adding 12 to its current value. Finally, the value of `N` is updated again by multiplying it by 3.

Here's the step-by-step execution of this part:

1. `N = 15` (initialization) 2. `N = N + 12` (N = 15 + 12 = 27) 3. `N = N * 3` (N = 27 * 3 = 81)

Therefore, the final value of `N` is 81.

# Part 2: N = 2; N = N * 25;

In this part, the variable `N` is initialized with a value of 2. Then, the value of `N` is updated by multiplying it by 25.

Here's the step-by-step execution of this part:

1. `N = 2` (initialization) 2. `N = N * 25` (N = 2 * 25 = 50)

Therefore, the final value of `N` is 50.

Summary

To summarize, the given code initializes the variable `N` with different values and updates its value using arithmetic operations. In the first part, `N` is initialized with 15, then updated by adding 12 and multiplying by 3, resulting in a final value of 81. In the second part, `N` is initialized with 2 and updated by multiplying it by 25, resulting in a final value of 50.
