C++关于构造函数可向父类或者本类传参的讲解

#include <iostream>#include <cstring>using namespace std ; //英雄联盟类 class Hero{ private : int blood ;  string name ; public : Hero(int blood = 100, string name = "man wang") { this->blood = blood ;  this->name = name ; } ~Hero() { if(this->blood < 0){  cout << "Hero blood error!/n" << endl ;  return ; } cout << "Hero name is:" << this->name << endl ;  cout << "Hero blood is :" << this->blood << endl ;  } }; //德玛类，继承于英雄类 class Dema : public Hero{ private : int blood ;  string name ; public : Dema(int blood , string name); ~Dema();};//在实现子类的构造函数时，可以同时向父类的构造函数传参//例如这个例子的 : Hero(58,JS),相当于向父类的构造函数传参//当然，子类也可以给本类的的成员传参Dema::Dema(int blood , string name) : Hero(89 , "JS") , blood(58) , name("dema"){ this->name = name ; this->blood = blood ; }Dema::~Dema(){ if(this->name != "dema"){ cout << "This Hero are no dema!" << endl; return ; } if(this->blood < 0){ cout << "Dema blood error!/n" << endl ; return ; } cout << "Dmea name is:" << this->name << endl ;  cout << "Dema blood is :" << this->blood << endl ; }int main(int argc , char **argv){ Dema player1(79,"dema"); return 0 ;}
