#include <stdio.h> void reverse_array(int *a, int n) { int *start = a; int *end = a + n - 1; while (start < end) { int temp = *start; *start = *end; *end = temp; *start++; *end-- } }

This code defines a function that reverses an array of integers by swapping elements from both ends toward the middle using pointers.

- The line `*start++;` increments the pointer but also dereferences it, which is not needed. The `*` operator is applied to the result of `start++`, which is the original pointer value, so the increment works but the dereference is unnecessary and confusing.
- The line `*end--` is missing a semicolon at the end, which will cause a compilation error.
