Changing Arduino Codes to WinAVR/Atmel Studio

Good afternoon, good people.
I'm still newbie about Arduino, so I'll thankfully for all who helped me with this case.
I'll make a project school and I found a code reference about project, but I still confuse about the code. My class is requested to make a code with WinAVR or Atmel Studio. Anyone can kindly help me? :sob:

Then you have no reason to move beyond the IDE. It is perfectly adequate for most projects.

My class is requested to make a code with WinAVR or Atmel Studio.

Why?

Have you installed either of those projects? Have you bothered to read the documentation that comes with them?

This is NOT a Programming issue.

And this isn't really the place to ask about Atmel Studio issues, note. The Arduino IDE and libraries
deliberately keep things very simple for the beginner - you may have a steep learning curve without it.
