Guys I have a BIG question for you, I want to make an educational software on a website which helps people to remove the errors from their code, for that I need a c++ compiler (someone can help me with that? i want to put it on the website), an auto-debugger...what means that? I want to process the code from a text-box (an html elemnt) like: if(a == b); the auto-debugger must show: correct sintax is: if(a == b) and you mistake is when you put ";". Someone can help me with that? My first necessity is the C++ compiler for an website, and the second is the auto-debugger pls help. :)) Here we can use HTML, PHP, MySql, Jscript, etc... I will post here the website after i finish those things, so stay tunned ;)
