Online IDE & Debugging Tool
2.) codepad
codepad.org is an online compiler/interpreter, and a simple collaboration tool. It’s a pastebin that executes code for you. You paste your code, and codepad runs it and gives you a short URL you can use to share it. Paste the URL into chat or email to get help or to show someone how to do something. Or just try things out when you don’t have an interpreter handy. It works well on many phones.
codepad works like a compiler or interpreter, not like the read-eval-print loop of an interactive interpreter prompt. If you want to print the value of an expression, you need to use your language’s print command. If your language requires a “main” function, your program won’t work in codepad without one.

8.) GCC Explorer
An intuitive web based tool targeted at C++ programmers and useful for researching,debugging and optimizing code has been made available.
One of the things I spend a fair amount of time doing at work is compiling my C/C++ code and looking at the disassembly output. Call me old-fashioned, but I think sometimes the only way to really grok your code is to see what the processor will actually execute. Particularly with some of the newer features of C++11 — lambdas, move constructors, threading primitives etc — it’s nice to be able to see how your elegant code becomes beautiful (and maybe even fairly optimal) machine code.
Having crafted a web-based tool for exploring the output of the compiler under small tweaks of the code, compiler version and compiler flags, Matt was given permission by his company to open source it.
9.) DJGPP Public Access Cross-Compiler
