标签：inter out assign col c++ ons int ann ssi 按英文的字面意思就比较好理解了： 常量指针：pointer to const 字面意思：指向常量的指针 指针常量：const pointer 字面意思：指针本身是个常量 看一段代码： 常量指针和指针常量 C / C++ 标签：inter out assign col c++ ons int ann ssi 原文地址：https://www.cnblogs.com/harrypotterisdead/p/14504864.html char hello[6] = "hello";
char world[6] = "world";
const char *p2const = hello; // pointer to const
char *const constp = hello; // const pointer
p2const = world; // value of p2const is "world"
// constp = world; // constant pointer cannot be reassigned
constp[0] = ‘y‘; // value of constp is "yello"
// p2const[0] = ‘y‘; // pointer to constant, cannot change the value
cout ‘ ‘ // "world yello"
