Variable number of parameters in function in C++

How I can have variable number of parameters in my function in C++.

Analog in C#:

public void Foo(params int[] a) {
    for (int i = 0; i < a.Length; i++)
        Console.WriteLine(a[i]);
}

public void UseFoo() {
    Foo();
    Foo(1);
    Foo(1, 2);
}

Analog in Java:

public void Foo(int... a) {
    for (int i = 0; i < a.length; i++)
        System.out.println(a[i]);
}

public void UseFoo() {
    Foo();
    Foo(1);
    Foo(2);
}
