一个指针可以操作两个实体,一个是指针值(即地址),一个是间访值(即指向的实体)。于是指针的常量性也分为两种:常量指针(pointer to constant)和指针常量(constant pointer)。 指针常量是相对于指针变量而言的,也就是指针值不能修改的指针。常量指针是指向常量的指针的简称。 定义指针常量还是常量指针就看const修饰,...

A null pointer constant can be used to initialize a pointer to null or to assign the null value to an existing pointer, it is one of the following values: An integer literal with value zero. A prvalue of type std::nullptr_t (usually nullptr). (since C++11)The...
can be cast to a reference to a type that is not const. The result is a reference to the original object. The original object was probably declared as const because it was to remain constant across the duration of the program. Therefore, an explicit conversion defeats this safety mechanism,...
