Hello,

Iam very newbie in programming and i have a task which shown above. I am trying to sort entries and i dont know if I did right in using char to alphabetically arrange the saved entries. I dont understand why the logBook[0] doesn't work in case 3. I also tried to save a 'date' as one of the arrays but i cant get wrap my head around it.

I really appreciate any help I could get. Thank you in advance.
