Question

_28. Using the following function prototype which statement about the argument passed to parameter Als true. void F(const int A[], int Cnt): A. The argument is modified when changes are made to parameter A in function F. B. The argument passed to parameter A must always have the same number of elements, every time function Fis invoked. C. Changes can not be made to parameter A in function F. D. Every element of the argument passed to parameter A must be initialized prior to invoking function F. _29 Given the declaration char Sentence[15]; and that the data entered from the keyboard is: The game is today what is the value stored into Sentence by the statement:cin>> Sentence; A. The B. The game is C. The game is tod D. None of the above. 30. The Newton-Raphson method algorithm for locating the root of a function is guaranteed to locate a root in a known number of iterations. A. TRUE B. FALSE 31. A better approximation of the area under a curve is by decreasing the trapezoid number used. A.TRUE B.FALSE 32. Which of the following is a disadvantage of the Newton-Raphson method? a. It converges more rapidly than many other methods. b. It requires you to be able to determine the derivative of the function which may not be easy to do. C. It may diverge if the guess is not close enough to the root of the equation. d. You have to guess many times to get a single root. 33 If a subscript in a C++ program is outside of the declared range for that array an error message specifying that the subscript is out of range will always be generated. A True b. False 34. Assuming the declaration statement char sentence[] = "Breath deeply"; the statement cout << sentence; will print the entire string Breath deeply. A. True B. False 35. Given the two-dimensional array declared by the following statement int myArray[4][3] = {{2,4,6},{1,8,10),(3,5,7),19,11,13}}; what is the value of myArray[1][2]? a. 4. b. 5 c. 8 d. 10

Answer 1

28) B

29) A ( it will store the characters upto its capacity but when space encounters it will print upto that value only ex:the pen return the only )

30) False (we can run infinite number of iterations to find perfect root for our function)

31) True

32) B (requires the calculation of derivative of function, which is not always easy )

33) False because c/c++ don't provide any specification which deal with problem of accessing invalid index

34) True

35) D (10) in array of array[1] contain {1,8,10} indexing start from "0" array[1][0]=1 array[1][1]=8 so array[1][2] stores value 10
