#include <iostream>using namespace std;int main(void){ //const int a; Error,常量必须初始化 const int a = 100; //a = 200; Error,常量不能重新被赋值 int b = 22; const int * p; //const在*左边，表示*p为常量，经由*p不能更改指针所指向的内容 p = &b; //*p = 200; Error,常量不能重新被赋值 //int * const p2; Error,p2为常量，常量必须初始化 int * const p2 = &b;//const在*右边，，表示p2为常量 //int c =100; //p2 = &c; Error,常量不能重新被赋值 *p2 = 200; cout << b << endl; return 0;}
到底通向了什么样的远方呢？
