nullptr_t is only convertible to bool as a direct-initializationIn C++11, nullptr is only convertible to bool as a direct-conversion; for example, when you initialize a bool by using a braced initializer-list. This restriction was never enforced by MSVC. MSVC now implements the rule under /...

断言,是宏,而非函数。assert 宏的原型定义在<assert.h>(C)、<cassert>(C++)中,其作用是如果它的条件返回错误,则终止程序执行。可以通过定义NDEBUG来关闭 assert,但是需要在源代码的开头,include <assert.h>之前。 使用 代码语言:javascript 代码运行次数:0 运行 AI代码解释 #defineNDEBUG// 加上这行,则 asser...

了解C++ 默默编写并调用哪些函数(编译器暗自为 class 创建 default 构造函数、copy 构造函数、copy assignment 操作符、析构函数) 若不想使用编译器自动生成的函数,就应该明确拒绝(将不想使用的成员函数声明为 private,并且不予实现) 为多态基类声明 virtual 析构函数(如果 class 带有任何 virtual 函数,它就应该拥有...
It means that the initialization of Base via the private default constructor happens directly, as part of the extended aggregate initialization rule. Previously, the Base private constructor was called via the Derived constructor, and it succeeded because of the friend declaration. The following ...
