Shifting an Array §

#include <iostream>
#include <cmath>
#include <chrono>
#include <thread>
 
int main()
{
    // caleb b
    // shifting an array
 
    int array[8];
    for(int i = 0; i < 8; i++)
    {
        std::cout << "Enter a number: " << std::endl;
        std::cin >> array[i];
    }
    std::cout << "Original Array: " << std::endl;
    for(int i = 0; i < 8; i++)
    {
        std::cout << array[i] << ", ";
    }

Harmonic Mean of an Array §

#include <iostream>
#include <cmath>

#include <thread>
 
int main()
{
    // caleb b
    // harmonic mean of an array
 
    double array[8];
    for (int i = 0; i < 8; i++) {
        std::cout << "Enter a number: " << std::endl;
        std::cin >> array[i];
    }
 
    double sum = 0;
    for (int i = 0; i < 8; i++) {
        sum += 1 / array[i];
    }
 
    std::cout << "Harmonic mean: " << 8 / sum << std::endl;
