C is one of the oldest programming languages that are still used by developers to write codes. C language is still used to develop system applications. It has been used for developing major operating systems including Windows, UNIX, and Linux. This is the reason most people who want to become a software engineers are taught the C programming language. C has features of both high-level and low-level languages. It can be used for low-level programming to write kernels and device drivers. It is also used to write software applications. If you are learning how to code in C, you need to install an IDE on your system that supports the C compiler. If you do not want to install anything on your system, there are several online C compilers. You can use these C compilers, to write and execute C codes online.
What is C?
C is a programming language declined ivy Dennis Ritchie at Bell laboratories for UNIX operating system. This programming language was initially released back in 1972. Most of the desktop operating systems, MySQL and Oracle are completely written in C.
What is an Online C compiler?
Online C compiler is a browser-based tool that lets you write and run C language codes online. Online C compilers are easy to use and really simple. You don’t need to install and configure a C compiler on your system for checking your C programming language codes.
You get a big Text area to write the code. When you are done, press the “Run” button to complete and execute it. Online C compilers also let you enter command-line arguments for console-based inputs or give text-based inputs.
There are several benefits of running C codes in the browser. Here’s a list.
- No IDE setup required
- Good for learning and tasing codes online
- Some services also let you collaborate with other people
- Backup your code on the cloud
- Online tools are accessible from any platform
