Beginner C++ question here!

I'd like to create a file called "numbers.txt" in onlinegdb, and then in my Main function I would like to open the file and read the data into an array of integers.

I'm not sure if this is possible, and if so, how could I get the file to open successfully? So far my program is running but it is telling me that the file could not be opened.

In order to read a file from a program you need to include it in the same project.  For example, you can have the data in data.txt and your code in myCode.  You can add additional files to your project using Ctrl + M.  When you list your projects, you will only be able to see the projects names but not the file they contain.  If you want to do so, you can download the project to your computer and unzip it.
