指针数组与数组指针

#include <iostream>#include <typeinfo>int main(){int n = 1;// intint array[2] = { 1, 2 };// int [2], 数组int *p = &n;// int *, 指针int **pp = &p;// int * *, 指针的指针int *parray[2] = { &n, &n };// int * [2], 指针数组int (*p2array)[2] = &array;// int (*)[2], 数组指针int (&ref2array)[2] = array;// int [2], 数组引用std::cout << "Declaration [int n = 1] type == " << typeid(n).name() << std::endl;std::cout << "Declaration [int array[2]] type == " << typeid(array).name() << std::endl;std::cout << "Declaration [int *p] type == " << typeid(p).name() << std::endl;std::cout << "Declaration [int **pp] type == " << typeid(pp).name() << std::endl;std::cout << "Declaration [int *parray] type == " << typeid(parray).name() << std::endl;std::cout << "Declaration [int (*p2array)] type == " << typeid(p2array).name() << std::endl;std::cout << "Declaration [int (&ref2array)[2]] type == " << typeid(ref2array).name() << std::endl;return 0;}
