常量指针(pointer to constant)和指针常量(constant pointer) 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
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 constant objects. Or even both. What's the real difference?
