<iostream> cannot be found.

I am quite new to coding with C++ and I am trying to begin on my windows 10 PC for the first time. I downloaded VSC and downloaded the proper extensions be begin coding with C++. Following extensions are "C/C++" - "C/C++ Extension Pack" - "Code Runner". My code runs correctly when I write a proper line but no matter what I attempt, I keep getting #9018. I have done everything the quick fix recommends but can't seem to find a proper solution. If anyone can help me understand what I must do, you would be a life saver as this is part of my uni work.
I see multiple attmepts on trying to solve this issue and the person attempting to help says to provide a "Log Diagnostics command".
I have no idea what that is and will also require help with that if possible.

View->Command Palette->C/C++: Log Diagnostics is the command to run.

You should remove all the system headers from your includePath setting in c_cpp_properties.json and make sure your compilerPath setting is set to a valid compiler.
