¿Has encontrado un error? ¿Tienes la solución? Deja tu correción ;-)

Antes de comentar: Gran parte de los ejercicios propuestos no tienen librerías debido a que Wordpress las eliminó al verlas como etiquetas HTML. Si sabes/tienes/conoces las librerías que hacen falta, déjalo en los comentarios. Y lo mas importante: Todos los ejemplos fueron realizados por estudiante con únicamente conocimiento básico del lenguaje, no de programación.

Punto importante: Si vas a sugerir un segmento de código en algún lenguaje debes hacerlo así:

  • Si es lenguaje C <code lang="c">Código en C</code>
  • Si es lenguaje Pascal <code lang="pascal">Aquí dentro el código de Pascal</code>.

De esta manera el código coloreas el código.
