41. A declaration "short int" is used for variables

which have a short duration in a program

which have short names

which may require less storage than normal integers

all of these

42. The declaration "unsigned u" indicates u is a/an

unsigned character

unsigned integer

character

none of' these

43. An external variable

is globally accessible by all functions

has a declaration

will be initialized to 0 if not initialized

all of these

44. Consider the declaration char street[10] = "abcdefghi"; Choose the correct remark(s)

&street and street will have different values

&street is meaningless

&street+1 and street+1 will have the same values

None of the above

45. A file is preferable to an array of structures because

file lives even after the program that created it terminates

memory space will not be wasted

there are many system tools to manipulate files

All of the abone

46. Choose the correct statements

Array stores data of the same type

Array can be a part of a structure

Array of structure is allowed

All of the above

47. Pick the correct answers if x is an one dimensional array, then

&x[ i ] is same as x + i - 1

*(x + 1) is same as *(&x [ i ])

*(x + i) is same as x[ i ]

both (b) & (c)

48. While sorting a set of names, representing the names as an array of pointers is preferable to representing the names as a two dimensional array of characters because

storage needed will be proportional to the size of the data

execution will be faster

swapping process becomes easier and faster

All of the above

49. If arr is a two dimensional array of 10 rows and 12 columns, then arr (5) logically points to the

sixth row

Fifth row

fifth column

sixth column

50. A set of names can be represented as a

two-dimensional array of characters

one-dimensional array of strings

one-dimensional array of pointers to character

All of above

51. Choose the correct statements

Strictly speaking C supports 1-dimensional arrays only

An array element may be an array by itself

Array elements need not occupy contiguous memory locations

Both (a) and (b)

52. Choose the statement that best defines an array

It is a collection of items that share a common name

It is a collection of items that share a common name and occupy consecutive memory location

It is a collection of items of the same type and storage class that share a common name and occupy consecutive memory locations

None of the above

53. If n has the value 3, then the statement a [++n] = n++ ;

assigns 3 to a [5]

assigns 4 to a [5]

assigns 4 to a [4]

what is assigned is compiler-dependent

54. C does no automatic array bound checking. This is

true

false

C's asset

C's shortcoming

55. The following program main() { static char a[3][4] = {"abcd", "mnop", "fghi"}; putchar(**a); }

will not compile successfully

results in run-time error

prints garbage

none of the above

56. If a two dimensional array is used as a formal parameter, then

both the subscripts may be left empty

the first (row) subscript may be left empty

the first subscript must be left empty

both the subscripts must be left empty

57. Under which of the following conditions, the size of an one-dimensional array need not be specified?

when initialization is a part of definition

when it is a declaration

when it is a formal parameter and an actual argument

All of the above

58. The maximum number of dimension an array can have in C is

3

4

5

compiler dependent

59. Consider the statement int val[2] [4] = { 1, 2, 3, 4, 5, 6, 7, 8} ; 4 will be the value of

val[0 ][ 3]

val[0][4]

val[1][1]

none of the above

60. The parameter passing mechanism for an array is

call by value

call by value-result

call by reference

none of these
