(Solved) : 2 Preconditions Postconditions 3 Points Following Functions Either Check Box Says Postcond Q44027972 . . .
2 Preconditions and Postconditions (3 points) For the following functions, either check the box that says the postcondition always holds when the function is given inputs that satisfy its preconditions or give a concrete counterexample: specific values of the inputs such that the preconditions (if there is one) holds and the postcondition does not hold. You don’t have to write any proofs. int fi(int x, int y) 1/@requires 0 < x && X <= y; 1/Censures result < 0; int f2(int x) //@requires x % 2 == 0; //@ensures X >= 0 || result > X; return x – y; return x / 2; @ensures always true? @ensures always true?
