Online C++ Compiler
Build, Run and Test your code online with our online C++ compiler. You can quickly login from anywhere and start working. Getting into our online compiler is very simple and fast. Enter your code by using online C++ compiler and see the output now.
Online C++ compiler is a great tool to get started with C++ programming instantly. They allow you to run C++ codes on the fly in your favourite browser without the need to:
- Install C++ compilers and
- Set up a C++ development environment in your system.
Sometimes, it is a bit tricky, especially on Windows, to install C++ compilers such as MinGW (Minimalist GNU for Windows Files). The packages downloaded using the official installer can cause various errors such as:
- Corrupted files
- API endpoints are not available
On the other hand, using online C++ compilers relieves us from all these formalities. It allows us to focus on actual C++ programming. These online C++ compilers are super fast and can be used to:
- Build, run and share your C++ programs online
- Collaborate on C++ projects online using these platforms
- Share these projects on social media and gain contributors
- Download these projects as per the needs
Online C++ compilers allow private coding. It means your program file is not public and cannot be accessed by anyone. This feature is beneficial for competitive programmers.
Apart from these, for debugging c++ programs, we can also use online C++ compilers.
Working of the Online C++ Compiler
Coding Ninjas provides us with one of the best online C++ compilers that efficiently operate and support multiple programming languages. The online compiler provided by Coding Ninjas allows users to build, run and test C++ programs online. It uses the GNU C++ v5.4.0 compiler to build C++ programs.
Given below are the details of the various components of the online C++ compiler:
Write code in the code editor (with syntax highlighting for more code readability). The code editor has several valuable features. Some of them are:
- It supports an unlimited number of characters in the program code.
- You can switch between light and dark themes as per your choice.
- Reset code any time to start from scratch.
- Expand the code editor for better visibility and standard IDE experience (press Esc to roll back).
The output window provides the output of your C++ program on pressing the Run button. If your code has errors, the Output Window shows the errors on pressing the Run button. The output window is completely resizable for a convenient display.
Custom Input Window
The online C++ compiler allows the users to provide custom input to their C++ programs. This feature benefits competitive programmers by allowing them to test their code for various corner cases quickly. Similar to the Output window, this window is also resizable.
Benefits of using C++ Compiler
No need to install a C++ compiler and set up a C++ development environment in your local system
Quickly code, compile and run your C++ programs on your favourite browser
Verify your program's output on corner test cases using the custom input feature.
Inclusive IDE experience using switchable dark and light themes and full-screen code features.
Applications of C++ Compiler
Execute C++ programs: Code, compile, run and debug C++ programs online using the online C++ compiler.
Competitive programming: Beneficial for competitive programmers to code and test their C++ solutions online.
Compile and run the C++ programs online
To run a C++ program, a user can write the code in the Code editor.
If the C++ program needs any input for its functioning, provide it in the Custom Input Window (STDIN).
Finally, click on the Run Code button.
The compiler currently uses the GNU C++ v5.4 compiler to compile your program and convert it to machine code.
The output is displayed on the Output Window (STDOUT) if your code has no errors.
Otherwise, the Output Window displays the errors encountered.
