反转c++中的数组

#include <iostream>

void reverseArray(int arr[], int size) {
    int left = 0;
    int right = size - 1;
    
    while (left < right) {
        // 交换左右指针所指向的元素
        int temp = arr[left];
        arr[left] = arr[right];
        arr[right] = temp;
        
        // 更新指针位置
        left++;
        right--;
    }
}

int main() {
    int arr[] = {1, 2, 3, 4, 5};
    int size = sizeof(arr) / sizeof(arr[0]);
    
    reverseArray(arr, size);
    
    for (int i = 0; i < size; i++) {
        std::cout << arr[i] << " ";
    }
    
    return 0;
}

#include <iostream>
#include <algorithm>

int main() {
    int arr[] = {1, 2, 3, 4, 5};
    int size = sizeof(arr) / sizeof(arr[0]);
    
    std::reverse(arr, arr + size);
    
    for (int i = 0; i < size; i++) {
        std::cout << arr[i] << " ";
    }
    
    return 0;
}
