Insertar código de programas en Latex

Sin comentarios

Para insertar código en sus documentos latex, el documento debe de estar estructurado más o menos de la siguiente manera:

En este ejemplo todo el código y el cuerpo del documento está en el archivo principal, si ustedes lo desean lo pueden separar.
