    Compara dos asignadores predeterminados. Dado que los asignadores predeterminados no tienen estado, dos asignadores predeterminados siempre son iguales.

    1) Devuelve true .
    2) Devuelve false .

    El operador != es sintetizado a partir de operator== .

    		(since C++20)

    Parámetros

    lhs, rhs - asignadores predeterminados a comparar

    Valor de retorno

    1) true
    2) false
