Como cerrar una matriz si no se encuentra el numero q se buska o al dar enter ¿Como imprimir la ubicación de un numero de una matriz y finalizar si no esta o si se da enter en blanco se cierra el programa? Se como imprimir la ubicación pero al momento de ponerle la sentencia de que no es el numero me manda el mensaje para decir que no esta el numero todas las veces hasta que encuentra el numero... AQUÍ ESTA EL CÓDIGO ES EL INICIO DE UN TRABAJO PERO NO SE COMO AYUDA PARA PODER ENTENDERLO....
