#include <iostream>

    double cheese;
public:
    Burger();
    double getPatty();
    double getBun();

    void setPatty(double p);
    void setBun(double b);
    void setCheese(double c);
    double hamburgerCalc(Burger b);

yum.setPatty(patty1);

cout << "A double cheeseburger will cost: $" << val3 << endl;
cout << endl << "Programmer: <snip>" << endl;

}


double Burger::getPatty()
{
return patty;
}

double Burger::getBun()
{
return bun;
}

double Burger::getCheese()
{
return cheese;
}

void Burger::setPatty(double p)
{
patty = p;
}
void Burger::setBun(double b)
{
bun = b;
}
void Burger::setCheese(double c)
{
cheese = c;
}

I am trying to run this program by typing:
g++ burgerClass.cpp -o burgerClass.o
but i keep getting this:
burgerClass.cpp: In function ‘int main()’:
burgerClass.cpp:78: error: ‘hamburgerCalc’ was not declared in this scope
burgerClass.cpp:79: error: ‘cheeseburgerCalc’ was not declared in this scope
burgerClass.cpp:80: error: ‘dcheeseburgerCalc’ was not declared in this scope

Anyone know what the issue is? thanks.

Your first problem is you delcare a constructor (in your .h file) but you don't reference it in the class functions (.cpp)... So put this:

Burger::Burger()
{

}

Your other problem is the fact you don't tell the compiler where the functions are (in which class) you declare an object of "yum" so use it..

double val1 = yum.hamburgerCalc(yum);
double val2 = yum.cheeseburgerCalc(yum);
double val3 = yum.dcheeseburgerCalc(yum);

I don't understand your code. You have a main, then more class functions.. I hope this isn't all in one file.
