c++ - 在局部范围内销毁对象

Question

假设我有以下代码:

void foo() {  
 {
    myclass object;
    object.do_something();
 }
 cout<<"hello"<<endl;
}

是 ~myclass() 保证 在本地作用域退出时调用，还是稍后调用时间(例如函数返回的时间)？

Answer 1

是的，这是有保证的:

[class.dtor] Destructors are invoked implicitly for ... a constructed object with automatic storage duration when the block in which the object is created exits.
