Problem: Find the maximum and minimum elements in an array.

Write a function that takes an array of integers as input and returns the maximum and minimum elements in the array.

#include <iostream> void findMaxMin(int arr[], int size, int& maxElement, int& minElement) {    maxElement = arr[0];  // Initialize maxElement with the first element of the array    minElement = arr[0];  // Initialize minElement with the first element of the array    // Traverse the array and update maxElement and minElement if necessary    for (int i = 1; i < size; i++) {        if (arr[i] > maxElement) {            maxElement = arr[i];        }        if (arr[i] < minElement) {            minElement = arr[i];        }    } } int main() {    int arr[] = {9, 5, 7, 2, 1, 6, 8};    int size = sizeof(arr) / sizeof(arr[0]);    int maxElement, minElement;    findMaxMin(arr, size, maxElement, minElement);    std::cout << "Maximum element: " << maxElement << std::endl;    std::cout << "Minimum element: " << minElement << std::endl;    return 0; }

In this example, we define the findMaxMin function that takes an array arr, its size size, and two references maxElement and minElement to store the maximum and minimum elements respectively. We initialize maxElement and minElement with the first element of the array. Then, we traverse the remaining elements of the array and update maxElement and minElement if we find larger or smaller values.

Finally, in the main function, we create an array, call the findMaxMin function, and print the maximum and minimum elements.

Feel free to modify and test the code with different arrays to practice further
