What is wrong with this class?

[Guest_imported]

Hi, I have the following header file and than the accompanying file implementation, I am wondering if anyone can tell me what is wrong with it. The problem that is happening is that it runs withour errors but than it does not allow me to CIN the two numbers. Also do I need a main function? and if so what would it look like, i tried it below but it didn't work

*******************************************
//Formula.h
Class Formula{
private:
int pie, quad;
int AddSub();
public:
Formula(int const a, int const b); // constructor
};

*****************************************
// Formula.cc
int main()
{
return 0;
}

Formula::Formula(int a, int b){
pie = a;
quad = b;
Addsub()
}

void Formula::Addsub(){
cin >> a >> b;

int pieval = pie + quad;
int quadval = pie - quad;

cout << pieval << '/n' << quadval;
}
*********************

you haven't define an object in main(),I think.

Soo how do I define an object in main? What does it look like? thanks

int main()
{
int a, b;
cin >> a >> b;
Formula f1(a, b);
return 0;
}

void Formula::Addsub(){

int pieval = pie + quad;
int quadval = pie - quad;

cout << pieval << '\n' << quadval;
}
