Question

25. Given the array declaration double xyz [20]: which of the following statements are true? a. The array may hold up to 20 elements which may be accessed by the subscripts 0 through 20 b. The array may hold up to 21 elements which may be accessed by the subscripts 0 through 20 c. The array may hold up to 21 elements which may be accessed by the subscripts 0 through 19 d. The array may hold up to 20 elements which may be accessed by the subscripts I through 20 e. The array may hold up to 20 elements which may be accessed by the subscripts 0 through 19 26. Given the code segment void swap (int x, int y) { int temp = x; x=y; y = temp ; If the original value in num1 is 7and and the original value in num2 is 8, after the function call swap (num1, num2) 7 will be stored in num2 and 8 will be stored in num1. a. True, because it returns a void b. False because the function uses an invalid algorithm c. True, because that is what swap does d. False, because the function needs to use pass by value parameters for the interchange to occur e. False, because the function needs to use pass by reference parameters for the interchange to occur 27. An advantage of a sequential search is its a. b. c. requirement that the array be sorted speed simplicity d. complexity e. efficiency
