ubuntu C++ VScode 指针练习 字符串数组 改变字符串数组中的元素

定义一个字符串数组，通过指针把数组里的第三个元素更改掉

#include <iostream>
#define n 4using namespace std;//n = 5;
string Array_str[n] = {"a","b","c","d"};
string *pointer_str = NULL;int main()
{for (int i = 0; i < n; i++){pointer_str = &Array_str[i];//cout << "Array_str["<< i <<"]=" << Array_str[i] << endl;cout << "i=" << i << "," << "*pointer_str=" << *pointer_str << endl;if (pointer_str == &Array_str[2]){*pointer_str = "e";Array_str[2] = *pointer_str;}}for (int i = 0; i < n; i++){cout << "Array_str["<< i <<"]=" << Array_str[i] << endl;}
}
