How to run C++ programs on the web inside a browser? [closed]

Question

Can one write a program in C++ and somehow make it run by someone else directly on the web, from a browser, without the other person having to download the .exe?

Answer 1

A few days ago I would've downvoted this to oblivion and left an unhelpful comment about how little sense that made. Yesterday, however, I read an article on /r/programming which has led me to now consider your question perfectly valid :). The technology is called Native Client (NaCl):

Native Client (NaCl for short) is a Chrome specific technology that allows developers to code in C/C++ and produce a .nexe file, a compiled native module. These run inside the NaCl sandbox in Chrome.

The article in question is here and is about browser game development, mainly using HTML5.

Answer 2

I suppose it depends on how complex a program you're talking about.

If you're referring to console applications which don't take too long to run, you can always use http://ideone.com/. For example: http://ideone.com/sGw5F
