Yeah, I understand the first part, but why the && and not ||. Sorry I'm spanish and I dont understand things like this in english haha. I understood the first part, but the condition is var sexo must be one of these, i first thought in || but my teacher told me that the || is not correct and the while never ends, but in && it works, but i think the condition catch all and must be sexo = hHmM, all at same time in &&, and in || the sexo var with one of the condition breaks, but not...this is that i cant understand
