Question

40 элементов массива найти сумму отрицательных элементов кратных 5

Answer 1

Var a:array[1..40] of integer;
i,s:integer;
begin
s:=0;
for i:=1 to 40 do begin
a[i]:=random(200)-100;
Writeln('a[',i,']=',a[i]);
if (a[i] mod 5=0) and (a[i]<0) then
s:=s+a[i];
end;
Writeln('Сумма отрицательных элементов кратных 5 равна: ',s);
end.

Answer 2

For i:=1 to 40 do begin   
if (a[i]<0) and (a[i] mod 5 =0) then k:=k+a[i];   
end;   
writeln;   
write('сумма ',k);

Answer 3

Finding the Sum of Negative Elements in an Array that are Multiples of 5

To find the sum of negative elements in an array that are multiples of 5, you can follow these steps:

1. Create an Array: First, create an array with 40 elements. This array will contain both positive and negative numbers.

2. Iterate Through the Array: Next, iterate through the array and identify the negative elements that are multiples of 5.

3. Calculate the Sum: Finally, calculate the sum of these identified negative elements that are multiples of 5.

Here's a simple example of how you might achieve this in JavaScript:

// Create an array with 40 elements
let array = [5, -10, 15, -20, 25, -30, 35, -40, 45, -50, 55, -60, 65, -70, 75, -80, 85, -90, 95, -100, 105, -110, 115, -120, 125, -130, 135, -140, 145, -150, 155, -160, 165, -170, 175, -180, 185, -190, 195, -200];

// Calculate the sum of negative elements that are multiples of 5
let sum = 0;
for (let i = 0; i < array.length; i++) {
  if (array[i] < 0 && array[i] % 5 === 0) {
    sum += array[i];
  }
}

console.log("The sum of negative elements in the array that are multiples of 5 is: " + sum);

This code creates an array with 40 elements and then calculates the sum of the negative elements that are multiples of 5.

Please note that the specific implementation may vary based on the programming language you are using.
