雙指針逆置數組的實現思路如下：
下面是一個簡單的示例代碼：
#include <stdio.h>
void reverseArray(int* arr, int size) {
int* start = arr;
int* end = arr + size - 1;
while (start < end) {
int temp = *start;
*start = *end;
*end = temp;
start++;
end--;
}
}
int main() {
int arr[] = {1, 2, 3, 4, 5};
int size = sizeof(arr) / sizeof(arr[0]);
reverseArray(arr, size);
printf("Reversed array: ");
for (int i = 0; i < size; i++) {
printf("%d ", arr[i]);
}
printf("\n");
return 0;
}
運行以上代碼，輸出結果為：
Reversed array: 5 4 3 2 1
