C Program to Find Largest Element in an Array using Pointers

// C program for the above approach
#include <stdio.h>
#include <stdlib.h>

// Function to find the largest element
// using dynamic memory allocation
void findLargest(int* arr, int N)
{
    int i;

    // Traverse the array arr[]
    for (i = 1; i < N; i++) {
        // Update the largest element
        if (*arr < *(arr + i)) {
            *arr = *(arr + i);
        }
    }

    // Print the largest number
    printf("%d ", *arr);
}

// Driver Code
int main()
{
    int i, N = 4;

    int* arr;

    // Memory allocation to arr
    arr = (int*)calloc(N, sizeof(int));

    // Condition for no memory
    // allocation
    if (arr == NULL) {
        printf("No memory allocated");
        exit(0);
    }

    // Store the elements
    *(arr + 0) = 14;
    *(arr + 1) = 12;
    *(arr + 2) = 19;
    *(arr + 3) = 20;

    // Function Call
    findLargest(arr, N);
    return 0;
