If you ask for a software recommendation, then your question is off-topic on this site. If you ask if anyone can implement this software for you, then no, since SO is not a coding service. Please make your question more specific and show what you have tried to answer it. — DYZ 18 secs ago

it sounds like your asking more of an architecture question. I would try posting this question on the software engineering stack exchange. Stack overflow is more of specific problems with a little bit of code. Software engineering is more for whiteboard problems. — Rico Kahler 40 secs ago

For anyone else, I found out this link explaining RAII better: tomdalling.com/blog/software-design/… — addons_zz 1 min ago

Unfortunately, questions asking us to recommend or find a book, tool, software library, tutorial or other off-site resource are off-topic here. However, you may find better luck SoftwareRecs.SE.

@VincentSavard in addition to what gnat said, you would be better off recommending users to search another site before posting. This question would likely be closed on Software Engineering as a duplicate of, well, take your pick from 64 similar questions. — Snowman 44 secs ago
