Volver a iterar
Publicado por Pedro (7 intervenciones) el 22/09/2022 09:39:30
Buenas, tengo el siguiente codigo, y quiero que, cada vez que insertas dos numeros y realizas una opercion, la consola te pregunte si quieres seguir operando o no. En caso de que si, te vuelve a pedir dos numeros, y en casod e que no pues nada se para la ejecución. He pensado que se tiene que hacer con un while o un if pero no se donde insertarlo para que funcione, ya que he probado varias cosas y he dejado la función en un bucle infinito
