我是C++领域的新手，面临着双指针。问题是如何在函数test中设置x=5？

#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);
}

这样做的方法是

(*pointer)->x = 5;
