C++子类继承父类的所有成员？私有是不继承还是被隐藏？

Question

今天学继承私有成员的时候，书上写父类的私有成员是无法被子类继承的。子类构造函数时要先调用父类的构造函数，那么当父类的构造函数有对父类的私有成员初始化时，子类创建一个对象，传入一个对应的原本该继承的私有成员的参数，那么这个参数有什么用？自己写了段代码测试下，结果这个参数改变了原有父类的私有成员。怎么会子类的参数反而改变了父类的成员？#include <stdio.h>class base{private: int baseprivate;public: base(int a) {        baseprivate=a; printf("父类构造...\n"); } ~base() { printf("父类析构...\n"); } void print() { printf("baseprivate=%d\n",baseprivate); }};class child :public base{public: child(int a,int b):base(b) {        childprivate=a; printf("子类构造...\n"); } ~child() { printf("子类析构...\n"); }private: int childprivate;};int main(){ base  obj1(1); obj1.print(); printf("父类创建完成//////////\n");    child obj2(1,2); obj2.print();    printf("子类创建完成//////////\n"); return 0;}这是结果 哪个大神告诉我下 怎么回事
