Assume that ip , jp , and tp have all been declared to be pointers to int and that result has been declared to be an array of 100 elements . assume further that ip has been initialized to point to an element in the first half of the array and that jp has been initialized to point to an element in the second half of the array .write some code that makes jp point to the element that ip was pointing to and that makes ip point to the element that jp was pointing to. instructor notes: here, you are swapping the pointers, not the values they point to.

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)?

The program below has been generalized to read a user's input value for hourlywage. run the program. notice the user's input value of 10 is used. modify that input value, and run again. generalize the program to get user input values for workhoursperweek and workweeksperyear (change those variables' initializations to 0). run the program. monthsperyear will never change, so define that variable as final. use the standard for naming final variables. ex: final int max_length

Create a console project in c#. 1. create an interface "imyinterface.cs" - add a method "string imessage()" 2. create a class named "c1.cs" - add 4 private data members, create property for each data member double loanamnout=0.0; double years=0.0; double interests=0.0; double interestrate=0.0; 3. - add a constructor with parameters to assign values to loanamnout, years, interestrate with values that user entered. 4. - add one method “payinterests()” to return the interests interests = loanamnout * interestrate * years 5. - inheritate "imyinterface", implement the method " imessage()", return string "be ready! ” 6. in program.cs, have users to enter loanamnout, years, interestrate. - call method payinterests() to display total interests. - call imessage() to display "be ready! ”
