Question

Составьте программу, которая заполняет массив б(1..10) случайными целыми числами в диапазоне от 1 до 10 и находит количество пар элементов с чётными значениями пример вывода Исходный массив : 10 2 4 1 3 5 7 8 количество пар чётных элементов = 2

Answer 1

#include <iostream>

 

int main()

{

 int b[10];

 for(int i=0;i<10;i++)

 { 

  b[i]=rand()%10+1;

 }

 int a=0;

 for(int i=0;i<9;i++)

 {

  if(b[i]%2==0 && b[i+1]%2==0)

   a++;

 }

std::cout<<"Чётных пар: "<<a<<std::endl;

system("PAUSE");

}

Program to Fill an Array and Find the Number of Pairs with Even Values

To accomplish this task, we can use Python to create a program that fills an array with random integers and then calculates the number of pairs with even values.

Here's a Python program to achieve this:

import random

# Fill the array with random integers in the range from 1 to 10
array = [random.randint(1, 10) for _ in range(10)]

# Count the number of pairs with even values
count = sum(1 for i in range(len(array)-1) if array[i] % 2 == 0 and array[i+1] % 2 == 0)

# Output the original array and the count of pairs with even values
print("Original array:", array)
print("Number of pairs with even elements:", count)

When you run this program, it will output the original array filled with random integers and the count of pairs with even values.

This program uses the `random` module to generate random integers and a list comprehension to fill the array. Then, it iterates through the array to count the number of pairs with even values.

This program provides a simple and efficient way to achieve the desired outcome.
