Top 10 online compiler site name:
1.) Ideone.com | Online IDE & Debugging Tool >> C/C++, Java, PHP, Python, Perl and 40+ compilers and interpreters
Online IDE & Debugging Tool
codepad.org is an online compiler/interpreter, and a simple collaboration tool. It’s a paste bin 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.
3.) Hackerearth Online Compiler
Compiles in the background, after every few keystrokes. The error lines are highlighted within a second after typing the code. Editor has syntax highlighting and autocomplete.
It supports C, C++, and Java, very close to real desktop IDE. It is super fast and easy to use. Suitable for students in classroom and assignments, practicing interview problems.
5.) Fiddle – jsFiddle – Online Editor for the Web
6.) JDoodle – Online IDE
Supports collaborative code.It just starts with a simple text area where you can paste code, and click run.
You can change the command line parameters and set the stdin before running the program.Best suited for many old languages that are not supported by new online editors, and you don’t want to install and configure each compiler for those languages.
7.) OnlineGDB | Online C, C++, Java, PHP Compiler
It supports C, C++, PHP and Java Compilers. The unique feature of OnlineGDB is, you can debug your code step by step. Once the code is written, it can easily be formatter to make it look nice.
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
This service is being provided as a convenience to users who need to be able to produce a small DOS program and do not have access to a DOS machine with a compiler on it.
