- in C++ Create a class person having 5 data members.• Name• Address• Cnic• Gender• AgeAll data members should be hidden by the use of the data hiding concept. These values will beinitialized using the child class constructor. For getting the values of these data members gettermethod will be created for all data members in the parent class i-e Person.class gene { public: gene( ); gene(string n, string cl); string get_genename( ); //required the user to input the gene name. void print( ); private: string name; string chromosomal_location; }; a. Define the class gene. b. What kind of function overloading is achieved in this code? c. Define the constructor gene(string n, string cl) in such a way that user will input the name of the gene, which will be assigned to the variable “name”. d.Run this complete program on your computer and paste the screenshots of the output. e. Are the following two constructor functions possible in this class code? i. gene(string n); ii. gene(string cl);C++ coding (do this in C++ programming)1. Implement the following using JAVA :- a. Design a class named Person and its two subclasses named Student and Employee. b. Make Faculty and Staff subclasses of Employee. Please note that, A person has a name, address, phone number, and email address. A student has a class status (freshman,sophomore, junior, or senior). You can define the status as a constant. • An employee has office & salary. • Afaculty member has office hours and a rank. • A staff member has a title. c. Draw a UML diagram of the system.
- C++ programing. In nature, scientists have determined there are two types of bees: friendly bees and mean bees. A friendly bee will only sting a mean person if they refuse to become nice when asked and will never sting people that are not mean. On the other hand, a mean bee stings everyone. Given the following classes, main and sample run, create classes that represent these bees. Use the given Bee class. class Person{ public: bool mean; //true means they are mean, false they are not meanbool stung; //true means they got stung, false means they did not get stung Person(bool mean) {this->mean=mean;stung=false; //all people start out not being stung } }; Main (sample run below): int main(int argc, char** argv){ Person p(true);Person p2(false);Person p3(true); class Bee{ public:virtual bool sting(Person &p)=0; }; Person p4(false); cout<<"p: mean-"<<p.mean<<", stung-"<<p.stung<<endl; cout<<"p2: mean-"<<p2.mean<<",….
