可以通过循环遍历数组，依次交换首尾元素的方式来逆序数组。具体代码如下：
#include <stdio.h>void reverseArray(int arr[], int size) { int temp; for (int i = 0; i < size / 2; i++) { temp = arr[i]; arr[i] = arr[size - 1 - i]; arr[size - 1 - i] = temp; }}int main() { int arr[] = {1, 2, 3, 4, 5}; int size = sizeof(arr) / sizeof(arr[0]); printf("Original array: "); for (int i = 0; i < size; i++) { printf("%d ", arr[i]); } reverseArray(arr, size); printf("\nReversed array: "); for (int i = 0; i < size; i++) { printf("%d ", arr[i]); } return 0;}运行结果：
Original array: 1 2 3 4 5 Reversed array: 5 4 3 2 1
