I was asked to write a code in C++ for a simple integer class that stores two variables, object1 and object2, and adds them into a third variable, object3.

Here was my initial code:
cpp
class obj1 {
    public int val = 1;
    return val;
}

class obj2 : obj1 {
    public int val1 = 2;
    return val1;
}

class virtual obj3 : obj2, obj1 {
    public int val3;
    val3 = obj1.val + obj2.val1;
    return val3;
}
I realized my approach was incorrect as I used inheritance instead of a single Integer class. My code had several issues, including incorrect class declarations, inappropriate use of return statements, and improper inheritance syntax. Here’s an improved version:

cpp
#include

class Object1 {
public:
    int val;
    Object1() : val(1) {} // Constructor to initialize val
};

class Object2 {
public:
    int val1;
    Object2() : val1(2) {} // Constructor to initialize val1
};

class Object3 {
public:
    int val3;
    Object1 obj1;
    Object2 obj2;

Object3() {
        val3 = obj1.val + obj2.val1; // Adding values from obj1 and obj2
    }

int getVal3() const {
        return val3;
    }
};

int main() {
    Object3 obj3;
    std::cout << "Value of val3: " << obj3.getVal3() << std::endl;
    return 0;
}
However, the correct approach should have been a single Integer class:

cpp
#include

class Integer {
private:
    int object1;
    int object2;

public:
    Integer(int obj1, int obj2) : object1(obj1), object2(obj2) {}

int add() {
        return object1 + object2;
    }
};

int main() {
    Integer obj(5, 10);
    int object3 = obj.add();
    std::cout << "The result of adding object1 and object2 is: " << object3 << std::endl;
    return 0;
}
I learned a lot from this experience and appreciate the opportunity to improve my skills.
