What different between main.cpp and dialog.cpp?

I'm going to use it to use raspberry pi interfacing with ADC. Which part I should make? Thanks

Sorry? What is the question? Are you asking how you should name your file? Name it whatever you like, you can even name it "mysuperprogramfile.cpp".

I know it might seem not nice to say it like this, but if you do not know that you should first learn C/C++.
