I work with erlang
I want to make a function that will check if the Cin and Id is not null
I tried with:
if Cin /= null && Id/=null -> {ok,Cin et Id sont différents de null};
true -> {nok,Cin et Id sont null}
end.
I know that the notion of '&&' does not exist in erlang
but I can not find the equivalent of this notion in erlang
