1. Which of the following is an illegal array definition?

Type COLOGNE:(LIME,PINE,MUSK,MENTHOL); var a:array[COLOGNE]of REAL;

var a:array[REAL]of REAL;

var a:array['A'..'Z']of REAL;

var a:array[BOOLEAN]of REAL;

2. Minimum number of interchange needed to convert the array 89,19,40,14,17,12,10,2,5,7,11,6,9,70, into a heap with the maximum element at the root is

0

1

2

3

3. A one dimensional array A has indices 1....75.Each element is a string and takes up three memory words. The array is stored starting at location 1120 decimal. The starting address of A[49] is

1167

1164

1264

1169

4. Size of the array need not be specified, when

Initialization is a part of definition

It is a declaratrion

It is a formal parameter

All of these

5. If S is an array of 80 characters, then the value assigned to S through the statement scanf("%s",S) with input 12345 would be

"12345"

nothing since 12345 is an integer

S is an illegal name for string

%s cannot be used for reading in values of S

6. If x is an array of interger, then the value of &x[i] is same as

&x[i-1] + sizeof (int)

x + sizeof (int) * i

x+i

none of these

7. What is the maximun number of dimensions an array in C may have?

Two

Eight

Twenty

Theoratically no limit. The only practical limits are memory size and compilers

8. For 'C' programming language

Constant expressions are evaluated at compile

String constants can be concatenated at compile time

Size of array should be known at compile time

All of these

9. O(N)(linear time) is better than O(1) constant time.

True

False

both (a) and (b)

none of these

10. Window NT

security model is based on the notion of user accounts

creates a security access token that includes the security ID for users

NT operates with client server model

all of these
