Can someone help me with this error in my project on Microsoft visual studio c++? So I have two cpp files( shown in photos) and want to run one after the other, or separately, but this error code popped up in my second file after my first cpp file(second photo) worked correctly when previously tested. I'm unsure why it popped up, can anyone explain what it means and how to get my files to run properly? Also, how can I have multiple cpp files in one project without having to create multiple projects for each
