If you are using a text editor without autosave, this can happen.

Try saving your code and running it again.

If you are using VSCode, I'd recommend enabling autosave.

Hope I could help!

This error occurs when we try to compile an empty file. Saving the file and then compiling it will help in this.

Problem statement:

Here we found the error in the program is that the code is working fine in the editor or online compiler, but i think you didnt save the code or any important thing is missing in the editor.

Alternate solution:

One more reason is even if you have written the main function but if you didnot save the .cpp file and try to compile it will give the same error.So make sure you have successfully saved the .cpp file and then compile and run your code.

Hope this will help since I have faced similar issue and I spent around hours to figure it out , Thanks.

I would like to add the code and its output for your reference. Code with Output picture in this link.
