Complexity:
Does not apply.
Execution:
Does not apply.
Solution:
// The class should have the following functions : class Box { private: int l=0; int b=0; int h=0; public: // Constructors: // Box(); Box() = default; // Box(int,int,int); Box(int len, int bre, int hei): l(len), b(bre), h(hei) {}; // Box(Box); Box(Box &other): l(other.l), b(other.b), h(other.h) {}; // int getLength(); // Return box's length int getLength() { return l;} // int getBreadth (); // Return box's breadth int getBreadth() { return b;} // int getHeight (); //Return box's height int getHeight() { return h;} // long long CalculateVolume(); // Return the volume of the box long long CalculateVolume() { return (long long) l*b*h;} //Overload operator < as specified //bool operator<(Box& b) bool operator<(Box& b) { return this->l < b.l || (this->b < b.b && this->l == b.l) || (this->h < b.h && this->b == b.b && this->l == b.l); } }; ostream& operator<<(ostream& out, Box& b) { out << b.getLength() << " "; out << b.getBreadth() << " "; out << b.getHeight() << " "; return out; }
