Creating a class that takes in values like an array?

[javaisgood1]

I know operator overloading can assign an object of data type X into another object of the same datatype.
like int a=1; int b; b=a;

My question is if it's possible to do the following:

int array[3] = {1,2,4}

Then how do I program my class to do the same?

Maybe like this:

#include <initializer_list>

using namespace std;

class Object
{
public:
  Object(initializer_list<int> numbers)
  {
    // use numbers
  }
};


int main()
{
  Object obj = {1, 2, 3};
}

You may be looking for an "initializer_list".

#include <iostream>
#include <initializer_list>
using namespace std;

template <typename T>
class Array {
    T*     m_a;
    size_t m_size;

public:
    Array(initializer_list<T> il)
        : m_size(il.size())
    {
        T* p = m_a = new T[m_size];
        for (const T& n: il) *p++ = n;
    }

    ~Array() { delete [] m_a; }

    size_t size() const { return m_size; }

    ostream& print(ostream& os) const
    {
        for (size_t i = 0; i < m_size; i++)
            os << m_a[i] << ' ';
        return os;
    }
};

template <typename T>
ostream& operator<<(ostream& os, const Array<T>& a) {
    return a.print(os);
}

int main() {
    int a[]{1, 2, 3, 4, 5};
    for (int n: a) cout << n << ' ';
    cout << '\n';

    Array<int> arr{6, 7, 8, 9, 0};
    cout << arr << '\n';
}
