There are plenty of open source C/C++ compilers. They are fairly complex bits of code, so the notion of "debugged easily" depends on your notion of what is "easy". However, the information on how they work is well documented.

If you want to debug compilers, and you have skills with that, offer your services to the development team of one of the open source compilers.

The key parts of most compilers are written in C itself, or in ASM.

The open compilers are well documented, but compilers are generally very complex indeed.

Bullshit.

from my computer science book;

Then what are they written in ? MonkeyLanguage?

>Then what are they written in ? MonkeyLanguage?
You can write the lion's share of a compiler in any language you please. The only real restriction would be the code generator, where you need a language that can write to your target format.

i didnt say that you couldnt, i said "most compilers" which is true.
