Debo haber perdido esta pregunta, así que aquí hay una versión que publiqué como respuesta en otro lugar. Es una versión basada en C quine. Compila y corre para obtener la siguiente línea de canción. Repita hasta aburrirse. Si el código dice "Hora de irse ...", ingrese la cantidad de cervezas la próxima vez que ejecute como argumento de línea de comando.
