Undefined Reference to my Person class in c++

Question

Hi all I'm getting this error in my code. It says undefined reference Class::function() eventhought i've declared everything in the header file and #include it in the cpp file

main.cpp - My main file

#include "person.h"

int main()
{
    Person person;
    person.setName("John");
    person.setAge(30);
    // print person's name and age
    person.getName();
    person.getAge();

    return 0;
}

person.h - My header file

#include <string>
// create a class named person
class Person
{
private:
    // declare private variables
    std::string name;
    int age;

public:
    // declare setter for name and age variable
    void setName(std::string name);
    void setAge(int age);

    // declare getter for name and age variable
    void getName();
    void getAge();
};

person.cpp - My person cpp file

#include "person.h"

void Person::setName(std::string name)
{
    this->name = name;
}

void Person::setAge(int age)
{
    this->age = age;
}

void Person::getName()
{
    std::cout << "Name: " << this->name << std::endl;
}

void Person::getAge()
{
    std::cout << "Age: " << this->age << std::endl;
}

Error:
