What does it mean?
I am working on classes and this error comes when I run the implentation of my class file.

//Implimentation of class player1 (player.cpp)

{
std::cout << "Enter your first and last name seperated by a space. Respectively?\n";
std::cin >> first_name >> last_name;
}

string player1 :: Get_FName()
//Pre: string first_name has been updated in Set_Name
