Functions

Inside-Class Function

• When a member function is declared inside the class body, it is called an inside class function

• inline by default

class A{
    public : 
    void show(){
        cout<<"Hello";
    }
}

Outside-Class Function

• When a function is declared inside the class but defined outside, it is called an outside class function

• not inline by default

class A{
    public :
    void show();
}

void A::show(){
    cout<<"Hello";
}

inline functions : This means the compiler may expand the function at the point of call to reduce function call overhead
