Homework Statement


I am totally lost with this assignment. I don't even know what to study in order to do it. I posted a file with the main feature of the assignment, so I am just wondering if you can orient me little bit. Any advise would be useful

First of all, what is a scanner and how does it relate to this assignment?

Thread is locked until @SuperSusanoo can send me a message showing some effort on this problem. The scanner part of a compiler is pretty straightforward if you read the textbook or other study materials...
