Using an online IDE just cuts through the hassle when you are not looking for any extra features except executing some code.Your C++ program is not running in Code::Blocks because you do not have a C++ compiler (a version of G++) installed, or if it is installed you have not configured the C++ compiler in the Code::Blocks compiler settings.

There are many online IDEs on the web, but this one is my favorite. Yep! You can compile all of your C code in your browser. And if you are not facing any problems and have successfully executed your HelloWorld code, don’t get too comfortable, the course is just beginning! Can I just skip this software and have an online IDE, please? Please comment below and I’ll be glad to help you out.

The icon has a yellow gear and a green play logo. Step 8: Write the code for Hello World and click the Build and Run icon located in the toolbar on the top. Step 7: Check the boxes shown below to include the files in the Debug folders. Notice how the default folder is the project folder we created in step 2. Step 6: Save the file with the extension ‘.c’ and your desired filename. Similarly, if you can’t see the Manager window on the left and the Log window at the bottom, you can select to view them from the ‘View’ drop-down. If you can’t see any toolbars, head on to the ‘View’ drop-down, select toolbars and select Main and Compiler, the toolbars should now appear on your screen.

Step 5: From the topmost toolbar, select the new file icon and create an empty file. Check the boxes as shown in the screenshot to create the debug files. Step 4: Make sure that the selected compiler is the one we just installed.
