Online compilers are interactive IDEs that enable you to compile source codes and execute them online in several programming languages. An online compiler has the same basic functionality as a standard compiler. The one difference is that all of a project or application’s source code is stored and executed online via a web browser. This significantly reduces both the hardware and the software required by programmers when working on any given project, allowing programmers and development teams to quickly begin projects for a wide range of platforms, devices, and operating systems. Online compilers are capable of compiling and working with a variety of programming languages like C, C++, Python, Java, and many more.
On our personal computers, we use different compilers to run our codes like Dev C++, Visual Studio, Turbo C++, etc. But for using an online compiler, we simply need to connect to the internet, enter our code, and run it. On the client-side, the online-compiler is just a single webpage that takes the code written by the user as an input and sends a request to the server to compile the written code. When the server gets the request, it determines in which language this code needs to be compiled and it may have all the local setup required to run and compile the program in that particular language. It creates the file with the appropriate extension with the code sent from the client-side and runs it. When it gets the result, it sends the result as a response to the webpage.
Why we need Online Compilers
Online compilers make it easy to run any source code in a variety of languages without the need to download specific software for your laptop. They also allow you to work on any operating system, all you need is a working internet connection. You need to write your code in the provided textbox area and click on the run command. Online compilers have a user-friendly interface and it is not difficult to start working with them. They provide an uncomplicated and simple method to code even while you are on the go. They also work well on smartphones, though the screen size may make it difficult for you to have a comfortable working experience. The error lines are highlighted after typing the code. The editors also have features like highlighting the syntax and auto completing the code. Some sites also allow you to save your code and update existing codes.
A few famous online compilers are:
