C++ 列表元素移动：将指定位置元素移至末尾

#include using namespace std;

int main() { int n, x; cin >> n; int arr[n]; for (int i = 0; i < n; i++) { cin >> arr[i]; } cin >> x;

int temp = arr[x-1];
for (int i = x; i < n; i++) {
    arr[i-1] = arr[i];
}
arr[n-1] = temp;

for (int i = 0; i < n; i++) {
    cout << arr[i] << " ";
}

return 0;

}
