Online C++ Compiler

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:

1. Install C++ compilers and
2. 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:

1. Corrupted files
2. 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:

1. Build, run and share your C++ programs online
2. Collaborate on C++ projects online using these platforms
3. Share these projects on social media and gain contributors
4. 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.

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:

Code Editor

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).

Output Window

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.

• 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.

• 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.

• 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.
