我已经在代码中创建了一些指针，但是结果却不是我期望的。

这是简单的代码：

int main(int argc, char const* argv[])
{
    int myInt = 23;
    int* ptr = &myInt;

    char* buffer = new char[8];
    memset(buffer, 0, 8);

    char** ptr2 = &buffer;

    std::cout << "ptr address is " << ptr << std::endl;
    std::cout << "buffer pointer is pointing to address " << buffer << std::endl;
    std::cout << "ptr2 pointer is pointing to address " << ptr2 << std::endl;
    std::cout << "Dereferencing ptr2 = " << *ptr2 << std::endl;
    return 0;
} 

这是运行代码的结果：

ptr地址是0x7ffde215a14c …
