Seg Fault when using ->GetString(" ") which is in a separate class - c++

Question

I'm practicing some basic C++ right now, and decided to create a class in a header file and the constructor, GetString, etc functions in a separate file.
When I create my object using
"Person Bob" and use "." the code works fine, but if I do Person* Bob, the SetName(x) function seg faults, when I use ->SetName(x, with x being a "abc" string or a string variable
Main.cpp
#include <iostream>
#include <string>
#include "namevalue.h"
using namespace std;
int main(){
Person Bob;
string temp = "bob";
Bob.SetName(temp);
Bob.SetMoney(3000);
cout << Bob.GetName() << " " << Bob.GetMoney() << endl;
return 0;
}
Person.h
#include <iostream>
#include <string>
#include <cstdlib>
#include <ctime>
using namespace std;
class Person{
public:
Person();
Person(int money, string name);
void SetName(string y);
void SetMoney(int x);
int GetMoney();
string GetName();
private:
int money;
string name;
};
Person.cpp
#include <iostream>
#include <string>
#include <cstdlib>
#include <ctime>
#include <array>
#include "namevalue.h"
using namespace std;
Person::Person(){
name = " ";
money = 0;
}
Person::Person(int x, string y){
SetName(y);
SetMoney(x);
}
void Person::SetMoney(int x){
money = x;
}
void Person::SetName(string x){
name = x;
}
int Person::GetMoney(){
return money;
}
string Person::GetName(){
return name;
}

If you declare a pointer variable, you need to populate it first with a valid instance. Otherwise, it is pointing to invalid memory and you will get the memory fault you are experiencing.
This should work.
Person* Bob = new Person();
Bob->SetName("Bob");
Bob->SetMoney(3000);
When you're finished, free the memory.
delete Bob;
