C++从双指针获取数据

Question

我是C++领域的新手,面对双指针.问题是如何设置x=5功能test？

#include <iostream>
using namespace std;

typedef struct _DoublePointer
{
    int x;
    int y;
} DoublePointer;

void test(_DoublePointer** pointer)
{

}

void main()
{
    _DoublePointer* pointer = new _DoublePointer;
    _DoublePointer** doublePointer = &pointer;
    test(doublePointer);
}

Answer 1

这样做的方法是

(*pointer)->x = 5;
