How can I check for a return value from base class fucntion to inherited class function ?

For example ,

class X{

public:

int makecups(int cups){

if (cups > 0)

//code

return 1;

else

return 0;

};

class Y : public X{

public:

int makecups(int cup){

// here i dont how to check for return values of 1 or 0 from base fucntion to continue code?

}

};
