Question

Create a class children, it should contain child’s name, last name and age as private variables. Class also should have constructor which allows initialization of all private variables of the class. Create 10 element array of objects from class children, where all objects should be initialized using the constructor. Create 10 element array of void objects from class children (use override), sort the initial array of objects according to the children age and write the sorted objects in the second, void array.

Answer 1

#include <iostream>
#include <string>
#include <algorithm>
using namespace std;

class Children {
private:
    string name;
    string lastName;
    int age;

public:
    // Constructor
    Children(string n, string ln, int a) {
        name = n;
        lastName = ln;
        age = a;
    }

    // Getter for age (needed for sorting)
    int getAge() const {
        return age;
    }

    // Display function
    void display() const {
        cout << name << " " << lastName << " - Age: " << age << endl;
    }

    // Operator override for sorting
    bool operator<(const Children& other) const {
        return age < other.age;
    }
};
