Question

Попытайтесь понять эту программу. Чему будет равен Х после её выполнения? У:=10//Пояснение: теперь У равен 10. Х:=10+У. У:=У-1

Answer 1

Если ты правильно переписал, то 20.
y:= 10;
x: = 10 + y;
то есть
x: = 10 + 10 = 20;
y:= y - 1;
то есть
y: = 10 - 1 = 9;
но это никак не влияет на x, т.к. эта операция идет уже после выполнения вычисления переменной!

Answer 2

Understanding the Program

The given program is written in a programming language, but it is not specified which language it is. However, we can still try to understand the program based on the provided code.

The program consists of three lines of code: 1. `У := 10` - This line assigns the value 10 to the variable У. 2. `Х := 10 + У` - This line assigns the value of the expression `10 + У` to the variable Х. The expression adds the value of У (which is 10) to 10, resulting in Х being assigned the value 20. 3. `У := У - 1` - This line subtracts 1 from the value of У and assigns the result back to У. Since У was initially assigned the value 10, subtracting 1 from it gives У the new value of 9.

Value of Х after Execution

After executing the given program, the value of Х will be 20. This is because the value of Х is assigned as the sum of 10 and У, which is 10. Therefore, Х will be equal to 10 + 10, which is 20.

To summarize: - У is initially assigned the value 10. - Х is assigned the value 10 + У, which is 10 + 10 = 20. - У is then updated to У - 1, which is 10 - 1 = 9. - Therefore, the final value of Х is 20.

Please note that the programming language used in the given code is not specified, so the interpretation of the code may vary depending on the language. The above explanation is based on the assumption that the code follows a typical programming language syntax and semantics.
