Assume that month is an int variable whose value is 1 or 2 or 3 or 5 or 11 or 12. write an expression whose value is "jan" or "feb or "mar" or "apr" or "may" or "jun" or "jul" or "aug" or "sep" or "oct" or "nov" or "dec" based on the value of month. (so, if the value of month were 4 then the value of the expression would be "apr"
again, conditional operator so i need to : and ? .
(month==1)? "jan": (month==2)? "feb": (month==3)? "mar": (month==4)? "apr":
(month==5)? "may": (month==6)? "jun": (month==7)? "jul": (month==8)? "aug":
(month==9)? "sep": (month==10)? "oct": (month==11)? "nov": (month==12)? "dec":
isn't quite right for the compiler i am currently using.

Suppose there is a relation r(a, b, c) with a b+-tree index with search keys (a, b).1. what is the worst-case cost of finding records satisfying 10 < a < 50 using this index, in terms of the number of records n1, retrieved and the height h of the tree? 2. what is the worst-case cost of finding records satisfying 10 < a < 50 and 5 < b < 10 using this index, in terms of the number of records n2 that satisfy this selection, as well as n1 and h defined above? 3. under what conditions on n1 and n2, would the index be an efficient way of finding records satisfying the condition from part (2)?
