Hi, I tried to run the code above (first 3 screenshots) but kept receiving the error message (last screenshot) which says "collect2.exe: error: ld returned 1 exit status." I've saved all files and included headers, why am I still getting that error.

First screenshot: header file

Second screenshot: cpp file

Third screenshot: main file

Fourth screenshot: error message

Thanks!
