Im using visual studio code and it is giving me an undefined reference error when I run the main.cpp that has a #include .h file and another cpp file to define the function. These files run perfectly on the online code editor called Replit but not with visual studio code.
Beer.h file
#include <iostream>
using namespace std;
class Beer
{
private:
string type;
string where;
double alcohol;
public:
Beer();
Beer(string,string,double);
string gettype();
void settype(string);
string getwere();
void setwere(string);
double getalcohol();
void setalcohol(double);
bool equals(Beer,Beer);
void serveAt(string );
void printinfo();
};
Beer.cpp file
