I want to build a website for my app company, do you recommend any c++ built frameworks I can use? I currently only know console c++ and intermediate Cocos c++.
In what way do you think your C++ skills will matter in the development of your website? Is there something you can do in C++ that you couldn't do equally effectively and more quickly in a different way?
Since this is supposed to be a professional website where you'll (presumably) be trying to sell something, consider that, to your visitors, how you developed it is completely irrelevant. Part of using the right tool for the right job is not doing pointless work, which you would be doing if you try to develop a website in C++ just because.
> but I would like to apply my c++ skills to this, to make it matter
You'd better be damn good at input handling then if you want to avoid all those buffer overflow attacks, SQL injection attacks and all manner of other nastiness, that existing solutions with 1000's of man-years of effort have already solved.
