Your program will calculate the occupancy rate for a hotel (the percent of rooms that are occupied). you are given the file occupants. txt which details which rooms in the hotel are occupied. each row of the file represents a floor in the hotel. you do not know ahead of time how many floors there are in the hotel (in other words, your program must work with an input file of this format that has an arbitrary number of rows). each room is represented by a single digit. if the value of the digit is 1 the room is occupied, and the digit is 0 if the room is not occupied. because each floor can have a different number of rooms, the sentinal value -1 is used to indicate that the end of data for that floor has been reached.

What is the output of the following program? #include using namespace std; class bclass { public: void print() const; bclass(int a = 0, int b = 0); //postcondition: x = a; y = b; private: int x; int y; }; class dclass: public bclass { public: void print() const; dclass(int a = 0, int b = 0, int c = 0); //postcondition: x = a; y = b; z = c; private: int z; }; int main() { bclass bobject(2, 3); dclass dobject(3, 5, 8); bobject.print(); cout < < endl; dobject.print(); cout < < endl; return 0 ; } void bclass: : print() const { cout < < x < < " " < < y < < endl; } bclass: : bclass(int a, int b) { x = a; y = b; } void dclass: : print() const { bclass: print(); cout < < " " < < z < < endl; } dclass: : dclass(int a, int b, int c) : bclass(a, b) { z = c; }
