Question

Описати функцію Even (K) логічного типу, яка повертає True, якщо цілий параметр K є парним, і False в іншому випадку. З її допомогою знайти кількість парних чисел в наборі з 5 цілих чисел.С++

Answer 1

Программа:

C++:

#include <iostream>

using namespace std;

int Even(int K) {

   if(K % 2 == 0) { return true; }

   else { return false; }

}

int main()

{

   int n, i, j, kolvo;

   kolvo = 0;

   cout << "Кількість цифр:";  cin >> n;

   for(i = 1; i <= n; i++) {

       cin >> j;

       if(Even(j) == true) { kolvo++; }

   }

   cout << kolvo;

}

Answer 2

To describe the function `Even(K)` in detail, it is a logical function that returns `True` if the integer parameter `K` is even, and `False` otherwise. This function can be used to determine the number of even numbers in a set of 5 integers.

To implement the `Even(K)` function, you can use the modulo operator `%`. The modulo operator returns the remainder when one number is divided by another. In the case of even numbers, dividing them by 2 will always result in a remainder of 0.

Here is an example implementation of the `Even(K)` function in Python:

def Even(K):
    if K % 2 == 0:
        return True
    else:
        return False

In this implementation, the function checks if the remainder of `K` divided by 2 is equal to 0. If it is, the function returns `True`, indicating that `K` is even. Otherwise, it returns `False`, indicating that `K` is odd.

To find the number of even numbers in a set of 5 integers, you can use the `Even(K)` function in a loop. Here's an example:

numbers = [1, 2, 3, 4, 5]
count = 0

for num in numbers:
    if Even(num):
        count += 1

print("The number of even numbers in the set is:", count)

In this example, the `numbers` list contains 5 integers. The `count` variable is initialized to 0. The loop iterates over each number in the list and checks if it is even using the `Even(K)` function. If a number is even, the `count` variable is incremented by 1. Finally, the program prints the total count of even numbers in the set.

Please note that this is just one way to implement the `Even(K)` function and find the number of even numbers in a set. There may be other approaches or variations depending on the programming language or specific requirements.
