Queue management part 2

Question

We continue to develop our Queue management system that we made in the previous module.
You are asked to add a new functionality: adding two queues together. The result should be a new queue, where the elements of the first queue come first, followed by the second queue's elements.
Given the Queue class, overload the + operator, so that the code in main works and successfully adds two queues.
Please explain the code below thanks

Answer 2

#include <iostream>
using namespace std;
class Queue {
int size;
int* queue;
public:
Queue() {
size = 0;
queue = new int[100];
}
void add(int data) {
queue[size] = data;
size++;
}
void remove() {
if (size == 0) {
cout << "Queue is empty"<<endl;
return;
}
else {
for (int i = 0; i < size - 1; i++) {
queue[i] = queue[i + 1];
}
size--;
}
}
void print() {
if (size == 0) {
cout << "Queue is empty"<<endl;
return;
}
for (int i = 0; i < size; i++) {
cout<<queue[i]<<" <- ";
}
cout << endl;
}
//your code goes here
};
int main() {
Queue q1;
q1.add(42); q1.add(2); q1.add(8); q1.add(1);
Queue q2;
q2.add(3); q2.add(66); q2.add(128); q2.add(5);
Queue q3 = q1+q2;
q3.print();
return 0;
}
