Visual Code C++ "No such file or directory" message when trying to compile

I just started to get into coding. I eventually got Javascript code to start working in Visual Studio Code.

But I am having significant trouble with C++.

The error message: error message and code

My tasks.json file: tasks.json

My launch.json file: launch.json

Could any explain to me, someone who's relatively new to this, how I can get this to properly work?
