Example: Largest Element using Iteration in C++

// Largest Element using Iteration
#include <iostream>
#include <limits> // Required for numeric_limits

int main() {
    // Step 1: Declare and initialize an array
    int arr[] = {12, 45, 9, 78, 23, 56};
    int n = sizeof(arr) / sizeof(arr[0]); // Calculate array size

    // Step 2: Initialize 'maxElement' with the smallest possible integer value
    // or with the first element of the array.
    // Using numeric_limits<int>::min() handles cases with all negative numbers.
    int maxElement = std::numeric_limits<int>::min(); 
    // Alternatively, for non-empty arrays, you can initialize with arr[0]:
    // int maxElement = arr[0];

    // Step 3: Iterate through the array
    for (int i = 0; i < n; ++i) {
        // Step 4: Compare current element with maxElement
        if (arr[i] > maxElement) {
            // Step 5: Update maxElement if a larger element is found
            maxElement = arr[i];
        }
    }

    // Step 6: Display the largest element
    std::cout << "The largest element in the array is: " << maxElement << std::endl;

    return 0;
