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,...
Constant Pointer to a Constant If you have understood the above two types then this one is very easy to understand as its a mixture of the above two types of pointers. A constant pointer to constant is a pointer that can neither change the address its pointing to and nor it can change ...

this points to the memory location of the current object. If there is a name conflict between a parameter and a member variable, this can be used to differentiate the member variable from the local parameter. the "this" pointer is constant (const), meaning it cannot be modified. Since this...
