Example: Find Min Max in Array (Simple Iteration) in C

// Find Min Max in Array (Simple Iteration)
#include <stdio.h>

int main() {
    // Step 1: Declare and initialize an array
    int arr[] = {12, 5, 89, 3, 27, 45, 9};
    int n = sizeof(arr) / sizeof(arr[0]); // Calculate the number of elements

    // Step 2: Initialize min_val and max_val with the first element
    int min_val = arr[0];
    int max_val = arr[0];

    // Step 3: Iterate through the rest of the array (from the second element)
    for (int i = 1; i < n; i++) {
        // Step 4: Compare current element with min_val and update if smaller
        if (arr[i] < min_val) {
            min_val = arr[i];
        }
        // Step 5: Compare current element with max_val and update if larger
        if (arr[i] > max_val) {
            max_val = arr[i];
        }
    }

    // Step 6: Print the results
    printf("Array elements: ");
    for (int i = 0; i < n; i++) {
        printf("%d ", arr[i]);
    }
    printf("\n");
    printf("Smallest element: %d\n", min_val);
    printf("Largest element: %d\n", max_val);

    return 0;
