/* Robots producing candies in a candy factory have the following integer attributes: - Performance (P) - Endurance (E) - Cost (C) A robot can produce P candies per hour for E consecutive hours. After E hours, the robot will be able to produce only 1 candy per hour. The operation cost of a robot is C dollars per hour. Create a program that takes the following inputs and produces the corresponding output, optimizing the efficiency of the robots: Input N X: the number of robots and the maximum cost you can afford. The N next lines contain individual robot attributes: P, E, and C. Output The maximum possible number of candies that can be produced with the given robots and the given maximum affordable cost. */ #include #include #include #include class Robot { private : Robot( int performance, int endurance, double cost ): performance_( performance ), endurance_( endurance ), cost_( cost ){ id = "Cy"; id += ( 'a' + (performance/200)%21 ); id += ( '0' + (endurance/50)%10); } friend class Robot_Co ; public : void print(); //private : int performance_; int endurance_; double cost_; std::string id; }; class Robot_Co{ public : static Robot_Co& contact(){ static Robot_Co office; return office ; } Robot_Co( Robot_Co& ) = delete ; Robot_Co operator = ( Robot_Co& ) = delete ; std::vector buyProducts( int amount, int scale ); private : // std::vector robots_shipped; Robot_Co(){} }; class Factory { public : Factory()=delete; Factory( std::vector ); ~Factory(){} Factory( Factory& ) = delete ; Factory operator = ( Factory& ) = delete ; //void add( Robot& ); void add( std::vector ); void valuate( double fund ); void print(); private : void organize(); std::vector robots_; }; void Robot::print(){ std::cout << " - " << id << ": " << performance_ << " C/h, " << cost_ << " $/h, " << "E = " << endurance_ << " h"; } Factory::Factory( std::vector robots ) { add( robots ); } void Factory::add( std::vector in ){ robots_.insert( robots_.end() , in.begin() , in.end() ); organize(); } void Factory::organize(){ std::sort( robots_.begin() , robots_.end() , []( const Robot& a, const Robot& b )->bool{ return ( a.performance_ / a.cost_ ) > ( b.performance_ / b.cost_ ); }); } void Factory::print(){ std::cout<< "We have " << robots_.size() << " Robots:\n"; for ( std::vector::iterator it = robots_.begin() ; it != robots_.end() ; ++it ){ it->print(); std::cout<::iterator it = robots_.begin() ; it != robots_.end() ; ++it ){ if ( fund <= 0 ) break ; workTime = fund / it->cost_; if ( workTime > it->endurance_ ) workTime = it->endurance_; partialProd = workTime * it->performance_; partialCost = workTime * it->cost_; fund -= partialCost ; tot += partialProd ; std::cout << " => " << it->id << " : " << partialProd << " candy produced in " << workTime << " h, " << partialCost << "$\n" << "Remaining fund: " << fund << "$\n"; } if ( fund > 0 ){ std::cout<<"fund"; std::vector::iterator it = robots_.begin(); std::vector::iterator lessExp = it; it++; for ( it ; it != robots_.end() ; ++it ) if ( it->cost_ < lessExp->cost_ ) lessExp = it; partialProd = fund / lessExp->cost_; partialCost = partialProd * lessExp->cost_; fund -= partialCost ; tot += partialProd ; std::cout<< lessExp->id << " : " << partialProd << " candy at " << partialCost << " $\n" << "Cost x Candy : " << partialCost / partialProd << " $/C\n"; } std::cout<< " Final balance : " << tot << " candy produced, " << fund << "$ rested\n"; } #include std::vector Robot_Co::buyProducts( int amount, int scale = 0 ){ if ( scale < 1 ) scale = 1; else if ( scale > 20 ) scale = 20; if ( amount < 1 ) amount = 1; else if ( amount > 20 ) amount = 20; std::vector someRobots; for ( int i = 0 ; i < rand()%amount+1 ; ++i ){ int performance = rand()%1000 * scale +2; someRobots.push_back( Robot( performance, rand()%10 * scale+2, scale * performance /100.0+30.0 ) ); } return someRobots ; } #include int main() { srand( time( 0 ) ); Factory candy_co( Robot_Co::contact().buyProducts( rand()%30, rand()%30 ) ); candy_co.print(); std::cout<< "\n"; double funds = rand()%1000/12.34*511; candy_co.valuate( funds ); return 0; }
