Example: Find Max and Min in Array in C

// Find Max and Min in Array
#include <stdio.h>

int main() {
    // Step 1: Declare and initialize an array
    int arr[] = {12, 5, 89, 3, 72, 1, 45};
    int n = sizeof(arr) / sizeof(arr[0]); // Calculate the number of elements

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

    // Step 3: Iterate through the array starting from the second element
    for (int i = 1; i < n; i++) {
        // Step 3a: Compare current element with max_val
        if (arr[i] > max_val) {
            max_val = arr[i]; // Update max_val if current element is greater
        }

        // Step 3b: Compare current element with min_val
        if (arr[i] < min_val) {
            min_val = arr[i]; // Update min_val if current element is smaller
        }
    }

    // Step 4: Print the maximum and minimum values
    printf("The given array is: {");
    for (int i = 0; i < n; i++) {
        printf("%d", arr[i]);
        if (i < n - 1) {
            printf(", ");
        }
    }
    printf("}\n");

    printf("Maximum element in the array: %d\n", max_val);
    printf("Minimum element in the array: %d\n", min_val);

    return 0;
