Question

Создать одномерный числовой массив из 6 элементов и вывести результат на экран. Затем элементы, стоящие на нечетных местах уменьшить на 2, подсчитать сумму этих элементов и вывести эти значения на экран с пояснениями

Answer 1

Program n1;
const n=6;
var a: array [1..n] of integer;
sum,i: integer;
begin
sum:=0;
for i:=1 to n do
begin
a[i]:=random(15)+1;
write(a[i],' ');
if i mod 2<>0 then sum:=sum+a[i];
end;
writeln;
writeln(sum/2);
end.

Answer 2

Creating and Modifying an Array in JavaScript

To create a one-dimensional numeric array with 6 elements and display the result on the screen, you can use JavaScript. Here's an example code snippet that accomplishes this:

var array = [1, 2, 3, 4, 5, 6];
console.log("Original array:", array);

In this code, we declare an array variable named `array` and initialize it with 6 elements: 1, 2, 3, 4, 5, and 6. We then use `console.log()` to display the original array on the screen.

Modifying Odd-Indexed Elements and Calculating Their Sum

To modify the elements at odd positions (indexes) in the array by subtracting 2 from them, and then calculate the sum of these modified elements, you can use a loop. Here's an example code snippet that accomplishes this:

var sum = 0;
for (var i = 1; i < array.length; i += 2) {
  array[i] -= 2;
  sum += array[i];
}

console.log("Modified array:", array);
console.log("Sum of modified elements:", sum);

In this code, we declare a variable `sum` and initialize it to 0. We then use a `for` loop to iterate over the odd-indexed elements of the array. Inside the loop, we subtract 2 from each odd-indexed element and update the `sum` variable by adding the modified element to it. Finally, we use `console.log()` to display the modified array and the sum of the modified elements on the screen.

Example Output

When you run the above code, you should see the following output:

Original array: [1, 2, 3, 4, 5, 6]
Modified array: [1, 0, 3, 2, 5, 4]
Sum of modified elements: 6

In the modified array, the elements at odd positions (indexes 1, 3, and 5) have been reduced by 2. The sum of these modified elements is 6.

Please note that the code provided is a basic example to demonstrate the concept. You can modify it according to your specific requirements.
