When do we call function as function(object); and whn as object.function(); in object oriented programming in c++.

Question

when to use

Answer 1

Let's say you have a function in a class:

class ValentinHacker
{
public: void function (int test)
{
cout << test;
}
};

// in your main function:

int main()
{
ValentinHacker obj; // declare object of class
int num = 0;

obj.function(num); // prints num

return 0;
}

------- -------

The 'obj' in obj.function() is the class object to specify that function() belongs to the class.

The 'num' in function(num) is a variable which is passed into the function.
