title: Parallel data to serial in C/C++ : Implementing a multiplex
body: <p>I began working on the implementation of a basic parallel to serial data converter (MUX) in C or C++. Basically, this program takes data from some files and shows them in serial in a single file. </p>
  
  <p>I started with this, I searched on the internet and I didn't find much information.<br>
  Is there any library that I can use? Or any suggestions or guides?<br>
  If you have some information, regardless of programming language, please share.</p>
