bool operator==(const MyAlloc& other) const const 元素 C++ 标准始终禁止 const 元素(如 vector<const T> 或set<const T>)的容器。 Visual Studio 2013 及更早版本接受此类容器。 在当前版本中,此类容器无法编译。 std::allocator::deallocate 在Visual Studio 2013 和早期版本中,std::allocator::deallocate...
Constructors and destructors also have a slight penalty associated with them. These special methods are guaranteed to be called each time an object of the type is created or goes out of scope, respectively. However, this small amount of overhead is a reasonable price to pay for fewer bugs....

(Simple) Every constructor should initialize every member variable (either explicitly, via a delegating ctor call or via default construction). (简单)所有的构造函数都应该初始化每个成员(可以明确地通过委托构造函数或默认构造函数) (Simple) Default arguments to constructors suggest an in-class initializer...
void set_bit3(void) { a |= BIT3; } void clear_bit3(void) { a &= ~BIT3; } 一些人喜欢为设置和清除值而定义一个掩码同时定义一些说明常数,这也是可以接受的。我希望看到几个要点:说明常数、|=和&=~操作。 访问固定的内存位置(Accessing fixed memory locations) ...
The current compiler correctly gives an error, because the template parameter type doesn't match the template argument (the parameter is a pointer to a const member, but the function f is non-const): Output Copy error C2893: Failed to specialize function template 'void S2::f(void)'note:...
