C++ 构造器问题 初始化对象的时候就赋值

Question

#include<iostream>

using namespace std;

class xiuzhenjie{

        public:// 构造函数
        xiuzhenjie(int a, int b){
        this->alter = a;
        this->geschlecht =b;
        }
        // 构造函数
        xiuzhenjie(int a){
        this->alter = a;
        }


        public:
        int alter;
        int geschlecht;
};

int main()
{

xiuzhenjie tianyuanyu(13,1); // 1
xiuzhenjie* daluotianyu = new xiuzhenjie(14,1);
xiuzhenjie* daxiahuangchao = new xiuzhenjie(13);
int talent1 = 0;
int talent2 = 0;
talent1 = (daluotianyu->alter)*(daluotianyu->geschlecht);
talent2 = (tianyuanyu->alter)*(tianyuanyu->geschlecht);

cout<<"此人的资质："<< talent1 << endl;
cout<<"此人的资质："<< talent2 << endl;
return 0;
        }

xiuzhenjie tianyuanyu(13,1); // 1

什么样的构造器才能实现这样直接赋值？

Answer 1

引用类型初始化，好像必须new去分配空间，
