#include "myqueue.cpp"
Don't include source (*.cpp) files, only include header (*.h;*.hpp) files.
Thanks that handled some errors. But now I'm having issues with myqueue.cpp file.
You forgot the return types on some of the functions (isEmpty and isFull).
It would be incredibly easy if you just read the error messages that your compiler is giving you.
