本文通过实例详细解析了C++中不同类型声明的方式及其含义，包括基本类型、数组、指针及引用等，有助于理解复杂声明。

#include <iostream> #include <typeinfo> int main() { int n = 1; // int int 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; }
