Question

Program Primer; Var M,result : real; Begin Writeln('Введите значения переменной M'); Write('M='); Readln(M); Result := sqr((1+M)*3); Writeln ('sqr((1+M)*3)', result:8:0); Readln; End. Запусти Паскаль, введи данную программу, получи результат, если M=2.

Answer 1

Ну запустил)) ответ 81, это все?)

Answer 2

I'm sorry, but as an AI language model, I am unable to execute or run code directly. However, I can help you understand what the provided Pascal code does and how to manually calculate the result for a specific value of M.

Let's break down the provided Pascal code:

scssCopy code
Var
  M, result: real;

Begin
  Writeln('Введите значения переменной M');
  Write('M=');
  Readln(M);

  Result := sqr((1 + M) * 3);

  Writeln('sqr((1+M)*3)', result:8:0);
  Readln;
End.

Explanation of the code:

1. Var M, result: real;: This declares two variables, M and result, both of type real, which is used to represent floating-point numbers.

2. Writeln('Введите значения переменной M');: This line prints the message asking the user to enter the value of variable M.

3. Write('M=');: This line prints 'M=' and waits for the user to input a value for M.

4. Readln(M);: This line reads the user's input value and assigns it to the variable M.

5. Result := sqr((1 + M) * 3);: This line calculates the result using the input value of M. It adds 1 to M, then multiplies the sum by 3, and finally calculates the square of the result. The outcome is stored in the variable result.

6. Writeln('sqr((1+M)*3)', result:8:0);: This line prints the text "sqr((1+M)*3)" along with the calculated value of result. The ":8:0" format specifier ensures that the result is displayed with 8 characters, no decimal places.

7. Readln;: This line waits for the user to press Enter before the program exits.

Now, to manually calculate the result when M=2:

1. Substitute the value of M with 2 in the expression: Result := sqr((1 + M) * 3);
2. Calculate (1 + M) * 3: (1 + 2) * 3 = 3 * 3 = 9
3. Calculate sqr((1 + M) * 3): sqr(9) = 9 * 9 = 81

So, when M=2, the value of result will be 81.
