This is a topic that always confused me since the beginning: it's time to figure it out for good. In C and C++ you can have pointers that point to objects. But also constant pointers to objects. Or pointers to
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,...
Pointer to Constant As evident from the name, a pointer through which one cannot change the value of variable it points is known as a pointer to constant. These type of pointers can change the address they point to but cannot change the value kept at those address. A pointer to constant ...

例如对于内置类型而言,也就是(C-Like)Pass-by-value(通过值)通常要比Pass-by-reference(通过引用)要高效的多,然而,你从Cpart ofC++移动至Objecrt-Oriented,由于用户自定义(User-defined)构造函数以及析构函数的存在,Pass-by-reference-to-const(通过指向常量的引用)往往更好。

The implementation mechanism is simple: when it predicts a production, the parser pushes all of the right-hand side onto the stack, including terminals (to be matched), nonterminals (to drive future predictions), and pointers to action routines. When it finds a pointer to an action routine ...
在C 语言中,常量指针(Constant Pointer)是一种特殊的指针类型,它用于表示指针指向的数据是常量,即不能通过该指针修改所指向的数据。常量指针有助于保护数据不被意外修改,增强代码的安全性和可读性。 常量指针的定义 常量指针有两种形式: 指向常量的指针(Pointer to Constant): ...
