#include <iostream> #include <string> using namespace std;
//传入的参数是数组的指针,返回值是数组的指针 string (*fun(string (*s)[10]))[10] { return s; } //using str_arr = string (*)[10];
/*typedef string (*str_arr)[10];

*/
typedef string str_arr[10]; str_arr *fun1(str_arr *s) { return s; } auto fun2(string (*s)[10]) -> string (*)[10] { return s; } string d[10]; decltype(d) *fun3(decltype(d) *s) { return s; } int main(int argc, char *argv[]) { string s[10] = { "1", "2", "3", "4", "5", "6", "7", "8", "9", "1"}; //decltype(s) *ds = fun(&s); decltype(s) *ds = fun1(&s); //decltype(s) *ds = fun2(&s); //decltype(s) *ds = fun3(&s); (*ds)[1] = "han"; for (const auto &a : s) { cout << a << endl; } cout << endl; return 0; }
运行结果如下:
