سوال سوم: (برای آشنایی با دستور printf می توانید به این لینک مراجعه نمایید. اگر باز هم سوالی ماند در قسمت نظرات مطرح کنید.).

#include <iostream>
#include <iomanip> //setprecision
#include <cstdio> //printf

using namespace std;

class Cal{
    private:
        double _firstNum, _secondNum;
    public:
        Cal(double firstNum = 0, double secondNum = 0) : _firstNum(firstNum), _secondNum(secondNum) {} //intori neveshtan be tamiztar shodane code komak mikonad, faghat moshkel injast ke digar controli bar rooye meghdarDehi nadarim va inja niazi ham be aan nadarim
        
        double firstNum();
        double secondNum();

        void setFirstNum(double);
        void setSecondNum(double);

        double average();
        double sum();
        double multiply();
        double division();
};

double Cal::firstNum(){
    return this->_firstNum;
}

double Cal::secondNum(){
    return this->_secondNum;
}

void Cal::setFirstNum(double firstNum){
    this->_firstNum = firstNum;
}

void Cal::setSecondNum(double secondNum){
    this->_secondNum = secondNum;
}

double Cal::average(){
    return sum() / 2;
}

double Cal::sum(){
    return this->firstNum() + this->secondNum();
}

double Cal::multiply(){
    return this->firstNum() * this->secondNum();
}

double Cal::division(){
    return this->firstNum() / this->secondNum();
}

int main(){
    cout << fixed << setprecision(3);
    Cal* calculator = new Cal(1324.523251, 5465.2534);
    printf("First Number is %f And Second Number is %f.\nSum: %f\nAverage: %f\nMultiply: %f\nDivision: %f\n", calculator->firstNum(), calculator->secondNum(), calculator->sum(), calculator->average(), calculator->multiply(), calculator->division());
    return 0;
}

سوال چهارم:

#include <iostream>

using namespace std;

class Array{
    private:
        int* ar;
    public:
        Array();

        void set(int, int);

        int get(int);

        void sort();
};

Array::Array(){
    ar = new int[20];
}

void Array::set(int pos, int value){
    if (pos >= 0 || pos <= 20)
        ar[pos] = value;
}

int Array::get(int pos){
    if (pos >= 0 || pos <= 20)
        return ar[pos];
    else return -1;
}

void Array::sort(){
    for (int i = 0; i < 20; i++)
        for (int j = 0; j < 20; j++)
            if (ar[j] > ar[i])
                swap(ar[i], ar[j]);
}

int main(){
    Array* ar = new Array;
    for (int i = 0; i < 20; i++){
        int value;
        cin >> value;
        ar->set(i, value);
    }
    ar->sort();
    for (int i = 0; i < 20; i++)
        cout << ar->get(i) << " ";
    cout << endl;
    delete ar;
    return 0;
}
