Find Maximum Element Using Pointer Walk

Code

#include <stdio.h>

int find_max_element(int *ptr, int n) {
    // Your logic here
    int maxelement, i, *p;
    for (i=0, p=ptr, maxelement=*ptr; i < n; i++, p++) {
        if (*p > maxelement) {
            maxelement = *p;
        }
    }
    return maxelement;
}

int main() {
    int n;
    scanf("%d", &n);

    int arr[100];
    for (int i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
    }

    int result = find_max_element(arr, n);
    printf("%d", result);

    return 0;
}

Solving Approach

use a pointer to scan the array from top to bottom 

start by assuming maxelement is the first item. update as you scan
