C++面向对象编程，学生类案例

采用引用std简化

cpp 复制代码

#include <string.h>
#include <iostream>
using namespace std;

class Student{
	private:
		string name ;
		int age;
		string classname ;
	public:
		Student(string name,int age,string clsname ){
			this->age=age;
			this->name=name;
			this->classname=clsname;
		};
		Student(){
			this->age=18;
			this->name="susan";
			this->classname="2331";
		};
	
		void setName(string name){
			 this->name=name;
		};
		void show(){
		  cout<<"student name is "<<this->name+" classname"<<this->classname<<endl;
		};
		string getName(){
		   return this->name;	
		};
		
};

int main(){
	
	Student *s,s1("Lily",20,"2031");
   	s=new Student("Xiaoming",21,"2231");
    s->show();
    s= &s1;
    s->show();    
	s1.show();
	cout<< s->getName();
				
}

cpp 复制代码

//方案1，std采用静态类调用
#include <string.h>
#include <iostream>


class Student{
	private:
		std::string name ;
		int age;
		std::string classname ;
	public:
		Student(std::string name,int age,std::string clsname ){
			this->age=age;
			this->name=name;
			this->classname=clsname;
		};
		Student(){
			this->age=18;
			this->name="susan";
			this->classname="2331";
		};
	
		void setName(std::string name){
			 this->name=name;
		};
		void show(){
		  std::cout<<"student name is "<<this->name+" classname"<<this->classname<<std::endl;
		};
		std::string getName(){
		   return this->name;	
		};
		
};

int main(){
	
	Student *s,s1("Lily",20,"2031");
   	s=new Student;
    s->show();
    s= &s1;
    s->show();    
	s1.show();
	std::cout<< s->getName();
				
}

运行结果
