Array Reversal with Pointers

Overview

Implement a function that reverses an array using pointer arithmetic. Use two pointers - one at the beginning and one at the end - and swap elements while moving them toward the center. Stop when the pointers meet or cross.

The function should:

• Take an array pointer and size as parameters
• Use pointer arithmetic to traverse the array
• Handle edge cases like empty arrays or single elements

Implement a function that reverses an array using pointer arithmetic.

void reverseArray(int* arr, int size) {
    // TODO: Implement array reversal using pointer arithmetic
