Creat a class with name students this class sould inherit the students name and three data members (opp,math,English) from a class called subject which has a method to calculate the sum of the students degrees further the derivied class can acess a method student to calculate the students average in class called student average.

حل السؤال بالصيغة الصحيحة :

#include <iostream>
using namespace std;

class subjects
{
protected:
    string name;
    int oop;
    int math;
    int english;
    public:
    subjects(string name,int oop ,int math,int english){

       this->name=name;
       this->oop=oop;
       this->math=math;
       this->english=english;
    }

int sum()
{
      return oop + math + english;
}
};

    class studentavrage{
public:

void avrage(double s){
        cout << "Average: " <<s/3 << endl;
    }
};
class student:public subjects,public studentavrage{
    public:
student(string name,int oop,int math,int english):subjects(name,oop,math,english){}
};
        int main() {

            student s1("yas",90,77,56);
             double a= s1.sum();
            s1.avrage(a);

Ex1 :
Design a health care application to check the blood pressure of a patients. The application has a struct called patientPressure with a member variable (name, age, gender). Implement a method to issue the following message:

1- “name your blood pressure is high” if the systolic blood pressure is over 120mm Hg.
2- “name your blood pressure is normal” if the systolic blood pressure is between (100-120) mm Hg.
3- “name your blood pressure is low” if the systolic blood pressure is less 100 mm Hg.

Note: Instantiate an object called patient of type patientPressure.

#include <iostream>
using namespace std;

struct patientPressure {
    string name;
    int age;
    string gender;
    

    void issue(int pressure) {
        if(pressure > 120) {
            cout<< name << " your blood pressure is high " << endl;
        }

        if(pressure >= 100 && pressure <= 120) {
            cout<< name << " your blood pressure is normal " << endl;
        }

        if(pressure < 100) {
            cout<< name << " your blood pressure is low " << endl;
        }
    }
};


int main()
{
    patientPressure patient1 = {"salam", 34, "male"};
    patient1.issue(110);
    return 0;
}

EX2 :
A health care application, that specializes in tracking the weight of persons, has a class called personWeight with three variables (name, gender, and weight). Implement a method to give an appropriate message according to the following conditions:

1- “name you are overweight” if the person is male and his weight more than 80 kg else “you
are fit”.
2- “name you are overweight” if the person is female and his weight more than 60 kg else
“you are fit”.

Note: Instantiate an object called person of type personWeight. Use constructor to initialize the variables.

#include <iostream>
using namespace std;

class personweight {
    protected :
    string name;
    float weight;
    string gender;
    
    public : 
    personweight ( string n, float w, string g ) {
    name = n;
    weight = w;
    gender = g;
    }
    
    void printStatus() {
        if ( (weight > 80 && gender == "male") || (weight > 60 && gender == "female") ) {
            cout << name << " you are overweight" << endl;
        } else {
            cout << name << " you are fit" << endl;
        }
    }
};


int main() {
    personweight person1 = {"am_kean", 56, "female"};
    personweight person2 = {"abo_kean", 89, "male"};

    person1.printStatus();
    person2.printStatus();

    return 0;
}

are fit”.
2- “name you are overweight” if the person is female and his weight more than 60 kg else
“you are fit”.

Note: Instantiate an object called person of type personWeight. Use setter function to initialize the variables

#include <iostream>
using namespace std;

class personweight {
    protected :
    string name;
    float weight;
    string gender;

    public :

    weight = w;
    gender = g;
    }

    void printStatus() {
        if ( (weight > 80 && gender == "male") || (weight > 60 && gender == "female") ) {
            cout << name << " you are overweight" << endl;
        } else {
            cout << name << " you are fit" << endl;
        }
    }
};


int main() {

    personweight person1;
    person1.setinf ("am_kean", 56, "female");

    personweight person2;
    person2.setinf ("abo_kean", 89, "male");

    person1.printStatus();
    person2.printStatus();

    return 0;

Ex10 :
Design an application to calculate the area of any rectangle shape. The application should contain a class called Shape with two variables (length, width). Then generate a class with name (Rectangle) that publicly inherits the attributes of the other class, and has a method to calculate the area of any rectangle.
