推荐答案

类型。你会这样做：

void create() {
    int *obj1 = new int();
    int obj2;

    _obj1 = obj1;
    _obj2 = &obj2;
}

您认为这会有效吗？显然不是。
这很简单。你不能把指针传递给一个分配给堆栈的对象（根据经验，你不应该把指针传递给刚刚分配的对象，如果有人分配了一个对象， it）

Would you think this would work? Clearly not. It's very simple. You can't pass out the pointer to an object allocated to the stack (and, as a rule of thumb, you shouldn't pass out the pointer to an object you have just allocated. If someone allocates an object he is responsable to free it)
