	int* get_pointer_to_sum() const
	{
		return _sum;
	}

int main(){
        // is  this operation is right?

_sum.

The operations are valid, assuming an appropriate add_sum function exists, that you actually call the function on an object and that _sum points to a valid int instance and is not a member array.
Dereferencing the pointer after the last line would no longer be valid.
