Question

Составить программу, которая вычисляет сумму и среднее арифметическое положительных чисел.

Answer 1

Для начала каких чисел?

Они вводятся или нет?

Ох, ладно

Допустим, вводятся)

Python

Я ввожу число и все положительные числа, которые входят в него будут проходить через программу...

n = int(input())

g = 0

l = 0

for i in range(n+1):

   g += 1

   l += i

g -= 1

print( l // g )

Пример

Ввод: 5

Вывод: 3

Как получилось:

1+2+3+4+5=15

кол-во цифр = 5

15 / 5 =3

Как-то так

Answer 2

#### Program to Calculate the Sum and Average of Positive Numbers Here is a program written in C++ that calculates the sum and average of positive numbers: ```cpp #include int main() { int n; std::cout << "Enter the number of elements: "; std::cin >> n; int sum = 0; int count = 0; for (int i = 0; i < n; i++) { int num; std::cout << "Enter number " << i + 1 << ": "; std::cin >> num; if (num > 0) { sum += num; count++; } } double average = static_cast(sum) / count; std::cout << "Sum of positive numbers: " << sum << std::endl; std::cout << "Average of positive numbers: " << average << std::endl; return 0; } ``` This program prompts the user to enter the number of elements and then asks for each number one by one. It checks if the number is positive and adds it to the sum if it is. It also keeps track of the count of positive numbers. Finally, it calculates the average by dividing the sum by the count and displays the sum and average of the positive numbers. Please note that this program assumes the user will enter valid integer inputs. If the user enters non-integer values, the program may produce unexpected results.
