Why I get this random weird number C++ - c++

Question

I am new to using pointers with c++, so I am trying this small code but the problem is that when i try to print name i get this random weird number \364\277\357\376\326\241+\310\364\277\357\376\310. This is not the memory address, which is confusing and what confuses me more that when i replace name with getName() it works perfectly and prints the name! Thanks you!!
Person.cpp
#include "Pesron.hpp"
#include <string>
#include <iostream>
using namespace std;
Person:: Person()
{
}
Person::Person(string Name, int Age)
{
name=&Name;
age=Age;
}
void Person:: setName(string Name)
{
name=&Name;
}
void Person:: setAge(int Age)
{
age=Age;
}
string Person:: getName()
{
return *name;
}
int Person:: getAge()
{
return age;
}
void Person:: display()
{
cout<<*name<<" "<<age<<" ";
}
Person::~Person()
{
}
Student.cpp
#include "Student.hpp"
Student:: Student(string Name, int Age,int Grades, int ID):Person(Name , Age)
{
grades=Grades;
id=ID;
}
void Student:: setId(int ID)
{
id=ID;
}
int Student:: getId()
{
return id;
}
void Student:: setGrades(int Grades )
{
grades= Grades;
}
int Student:: getGrades()
{
return grades;
}
void Student:: display()
{
Person::display();
cout<<grades<<" "<<id<<endl;
}
main.cpp
#include "Pesron.hpp"
#include "Student.hpp"
#include "graduteStudent.hpp"
#include <iostream>
int main(int argc, const char * argv[]) {
// insert code here...
Student student("ZAID",21,2211,11);
student.display();
return 0;
}
Output
\364\277\357\376\326\241+\310\364\277\357\376\310 21 2211 11

Answer 1

Person::name looks like it is a std::string *. In Person::Person(string Name, int Age) you pass the paramater Name by value and then store the address of this local variable in name. When Name goes out of scope you have a dangling pointer.
(This also applies to void Person::setName(string Name))
Dereferencing Person::name is undefined behaviour, because the object it is pointing doesn't exist anymore. The solution is to simply store a std::string and not just a pointer to it.
So you get something like
class Person {
private:
std::string name;
int age;
public:
Person(std::string Name, int Age) : name(Name), age(Age) {}
};
