Question

Написать программу на языке Паскаль, где пользователь вводит с клавиатуры 99 элементов массива, а программа рассчитывает сумму значений элементом при условии четности индекса элемента и значения этого элемента.

Answer 1

Решение во вложении, при условии, что все элементы массива - целые числа

Answer 2

Writing a Pascal Program to Calculate the Sum of Even-Indexed Elements in an Array

To write a Pascal program that calculates the sum of values in an array based on the condition of even-indexed elements, you can follow these steps:

1. Declare an array with a size of 99 elements. 2. Prompt the user to enter the values for each element of the array. 3. Calculate the sum of the values of even-indexed elements. 4. Display the sum to the user.

Here's an example of how the program could be written in Pascal:

program SumOfEvenIndexedElements;

var
  arr: array[1..99] of Integer;
  i, sum: Integer;

begin
  // Prompt the user to enter the values for each element of the array
  for i := 1 to 99 do
  begin
    Write('Enter the value for element ', i, ': ');
    Readln(arr[i]);
  end;

// Calculate the sum of the values of even-indexed elements
  sum := 0;
  for i := 2 to 99 step 2 do
  begin
    sum := sum + arr[i];
  end;

// Display the sum to the user
  Writeln('The sum of the values of even-indexed elements is: ', sum);

Readln;
end.

In this program, we declare an array `arr` with a size of 99 elements. We then use a loop to prompt the user to enter the values for each element of the array. Next, we calculate the sum of the values of even-indexed elements by iterating over the array using a loop that starts at index 2 and increments by 2. Finally, we display the sum to the user.

Please note that this is just one way to write the program, and there may be other variations or optimizations depending on your specific requirements.
